ISR 3945 second power supply...

... is plugged in, cable is connected to the power socket, and CLI output still shows:
SYSTEM POWER SUPPLY STATUS
==========================
Internal Power Supply 1 Type: AC
Internal Power Supply 1 12V Output Status: Normal
Internal Power Supply 2 Type: Unknown
Internal Power Supply 2 Input Status and 12V Output Status: Fail
I never dealth with physical aspects of Cisco devices before, and I`m not sure is there anything specific that needs to be done except plugging in the second PSU?

Hi Milos im having the same problem than you, I have two C3945 and both of them presents the problem.
The power supply is power on and connected in both sides of the cable (green led), but in CLI it shows fail status. It occurrs in the second power supply.
Did you solved the problem? Could you help me please
SYSTEM POWER SUPPLY STATUS

ISR 4451-x power supply 4500W holdup time

Hi, folks.
I'm experiencing an issue with an automatic transfer switch (AP7723) and the ISR 4451-X power supply.
When switch is transferring a power the ISR is falling to restart process (with no correlation if one or two power supply installed).
Recent specification for the ATS says that a maximum transfer time is 18ms, typical time 8-12ms
I couldn't find any reference for the holdup time for the power supply PWR-4450-AC, only those for the 4500 series (http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/hardware/catalyst4500e/installation/guide/Eseries/0aspecs.html)
Please, advice
Thanks in advance,

Second power supply - dangerous?

Dear all,
Please dont answer if you really dont know - but in my quest to find out what the problems are with my 6600GT - I'd like to know if I can hook a second power supply to give juice to the graphics card molex without hurting my computer or the card.
Specifically - will this cause problems with having a second ground between the actual motherboard and graphics card?
Anyone who really knows will be a great help - I have a feeling its my power supply (crappy antec) thats the culprit of my problems...
Thanks for any help,
Dan

So, I did a lot of googling and used one of my electronic engineer friends who said 'dont be a pussy, get it on. They are all grounded using the same power strip so its a common ground anyways.'
I also took some advice from here:
http://www.absoluteinsight.net/21
Where its a little explicit about what you need to do to get a second power supply up and running (the short of the pins is crucial to get it activated)
What happened?
Well, after all the things i mention here NV6600GT VTD128 Hangs
I tried the 2nd power supply, and was vastly dissapointed with EXACTLY THE SAME RESULT - the MSI 6600GT simply hangs after about a minute.
So, I go to the Asus site, and I download a BETA BIOS for my machine. I flash. I cry. The machine no longer posts.
Back to the shop for a new motherboard, new RAM, new hard disk, and a replacement card.
Good news is, a second spare power supply is a good way to determine if you have issues with your power supply, so yes, it seems the Antec is in no way to blame for the issues here.
Tomorrow my good friend Damien will attempt to use the card in his machine - and see if it was compatibility issues with my nforce2 machine.
Thanks to all for their posts and help, time for some RMA action.
Cheers,
Dan

G4 mini Random Shutdown; Now Won't Power On, Power Supply Problem?

Twice now, my G4 mini has simply turned off randomly. The first time, it eventually restarted, and all was good until today, when it did it again. This time, it simply won't power on, much less boot. I wanted to run this by someone else (no Mac people here but me) before I bought a second power supply.
What I've noticed:
*If I plug a cold power supply into the wall, and then into the mini, the mini lights up for maybe half a second, then turns off again.
*Then, leaving mini plugged in to the PS, if I uplug the PS from the wall, wait ~3-5 minutes, plug it back in, the mini will light up for 1/2 second again.
*If I then unplug the PS from the mini (but leaving the PS plugged into the PS), wait ~3-5 min again, then plug the PS back into the mini, nothing happens. No lights, fireworks, nada.
I have repeated every possible combination of plugged/unplugged mini/PS in several outlets throughout my building. It seems that if I have a "hot" PS the mini will not light up no matter what. If the PS is "cold", and has sat for a few minutes, the machine will try to boot.
All I can think is that something in the mini is tripping a safety on the PS, or the PS is just tripping on its own.
Bad PS?

It's possible the previous power supply failed in a way that caused damage to the system, or of course for another fault to have developed with these symptoms.
It's interesting that it worked, apparently properly, because that tends to suggest the fault is something new, or that you have power issues of another kind external to the Mac.
I would suggest you try and reset the PMU since this controls the power management functions of the system.
- Unplug all cables from the computer, including the power cord.
- Wait 10 seconds.
- Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
- Let go of the power button.
- Press the power button once more to start up your Mac mini.
This may not help much, but it's well worth trying.

Replacement Sawtooth G4 power supply - Specs?

Hello!
Well, a couple of months back, I discovered that the power supply fan in my 400mhz AGP (Sawtooth) G4 had stopped running. My interim fix? A powerful case fan, attached via Velcro to the outside of the case (sucking air out of the G4) with the power cable running through an empty PCI slot door. The open door and edges of this fan are sealed with strips of duct tape...
Needless to say, this is not an optimal way to run the G4. After some looking online, I discovered that it's possible to buy refurbished/used G4 power supplies for around $90, but I'd rather not spend that much on a used power supply, particularly since this is actually the second power supply fan failure on this G4 - the first when the G4 was only a year old - so I'm not thrilled about buying the same model Apple PSU!
On a visit to my local Fry's store, I noticed they had a large assortment of power supplies, and that they seem to be pretty much the same as the one inside the G4 now - makes sense.
-My basic question is, can I use one of these basic PC power supplies in the G4? What, specifically, do I need to check to ensure that I don't blow anything out?
-Also, is the "power plug" on the G4's logic board a standard configuration, or is it wired differently than the ports on other PC logic/mother boards?
-The PSU inside the G4 says that it has a maximum output of 237 Watts and 32 Amps. I assume I need to purchase one that's very similar in output - how large of a difference between this PSU's power rating and the new PSU's rating is too large?
-Finally, what kind of screwdriver do I need to pull the existing PSU out of the G4?
Again, I have a 400 mhz "Sawtooth" PowerMac G4 from 1999, with a 16 MB AGP Rage 128 video card, and many upgrades. (DVD burner, more RAM, new HDDs, USB 2 card)
Thanks a bunch,
-Dan

According to the linked Forum Topic, the SilenX brand fan (80mm x 25mm = 80mm square x 25mm thick) plugged directly into the power supply's circuit board without splicing wires. Even if you need to splice wires, you just leave enough of the original fan's wires intact by cutting them off close to the fan itself, then joining them to the identical wires on the new ones. Any store having electronic supplies will probably have the mini-wire connectors, that you slide over the spliced wires and crimp in place. Electrical tape doesn't hold up as well in hot environments. Don't leave any excess wire length laying about inside the power supply, touching some of the hot components. Use a small nylon wire tie to gather the excess wire together, and hold away from the circuit board's components. The power supply housing has two halves, that can be separated enough to access the fan, after removing some phillips machine screws. A Google search may provide a page with photos of the procedure. The case fan is 120mm square x 25mm thick. If you want to use the same connection point as the original, you may need to cut the wires close to the original fan and splice them to the new ones. Otherwise, those fans typically have a standard molex power connector, that readily plugs into an available power lead. When buying replacement fans, be sure to get ones that provide a high airflow (CFM rating) for the given speed (RPM) and noise level (db rating). The noise level is important, because even a new fan can be loud.

IMac 27" Power supply problems?

I'm on my second power supply on my iMac 27" about 6 months old. Wouldn't wake up from sleep (twice now). Luckily, it's still under warranty, but I'm wondering if anyone else is having the same problem or if I got a "lemon" iMac? It's a bummer being without a machine for a week every few months. Will Apple replace it or do I have to go through this every few months?

If you haven't already I would STRONGLY recommend buying Apple Care. On a computer that is covered by AppleCare if the same thing happens 3x Apple will replace the computer. If you aren't familiar with AppleCare it:
1. Extends the one year warranty to 3 total years from original date of purchase.
2. Offers AppleCare telephone support. This can be very useful if you are new to OS X or Macs.
You can buy AppleCare directly from Apple or you can frequently find it discounted from authorized Apple Resellers such as Amazon or LA Computer Company.
Also I don't know how good the power is to your area of the islands. If the machine is plugged into the wall or inexpensive power strip power fluctuations could be damaging the computer. I would recommend getting a UPS which will provide emergency power in the event of a full power loss, enough to do an orderly shutdown. It will also provide consistent power and finally almost all come with insurance in the event your machine is damaged by a power related problem while connected. In other words it offers another layer of peace of mind. Personally I have had good luck with APC products, you can find those at your local Costco, Office Supply store or computer store.

Can i use an external power supply to power second graphics card?

hello. i currently have an ATI 5870 in my 2010 Mac Pro. I want to throw a Quadro 4000 in there as well, but i need one more 6-pin power cable. can i plop the quadro into the second PCI slot, buy a PC desktop power supply and just let it sit on the outside next to my Mac Pro, and then just run a 6-pin power cable from the power supply into the Quadro? i realize that the Mac Pro door would could not be placed back on...but i could figure out some way to cover up the opening so that dust doesn't enter.
would this work? anyone tried?

Hi,
Just want to ask a question that is not clear on everything that I have read. If you don't switch off the external power what do you take the risk for? Could you burn something or the card will just continue to work (spin the fan) after you turn off the Mac Pro? Where is the dangerous part?
Thanks!

Power supply freezes after running vi second time

Hello,
I am just starting my adventures in brave new world of LabView and I run into a problem with my first serious vi which is controling CPX400DP power supply and DPO4104 oscyloscope.
What my vi should be doing:
First it sets current levels of both channels of power supply (e.g. 5V on first, 0V on second) and size of the jump (e.g. 0.5V). Then vi should change both current levels by size of the jump and repeat till the current levels of both channels would be reverse to the start value (in this case, 0V on first channel, 5V on second). Also before every current change the vi would save to file mean of measurements out of the waveform from oscyloscope.
What my vi is doing:
At first run it seems that it's doing everything in order (new text file with resonable numbers is created). However, when I try to run the vi a second time my power supply freezes short after few current changes. I can stop the execution of the vi in LabView (it does take a while though) but to successfully run the vi again I must reset my power supply (turn it off and on).
I tried to go around this problem by modyfing the vi in a way that it would do what I want multiple times during running the vi only once but unfortunately that didn't work.
If anyone would have any suggestions about what I am doing wrong or how to help fix this problem feel free to share I don't bite... much But seriously, I'm stuck with this problem for over a week and I'll be glad for any tips
Thanks!
Waldek.

Thanks for a suggestion Bill but could you elaborate a bit on "try inserting ;*OPC? after every setup command"? I understand what that would do, concept wise, but as a new user I don't know how to do that in LabView. And Good Uncle Google doesn't say anything about " ;*OPC? " and insist on talking about OPC servers instead.
I'm sorry - I was looking at the manual and failed to realize that the missing subVIs from your code were actually drivers for your power supply, so you may not be able to implement this (unless the drivers themselves have the "Operation Complete" capability - hopefully the drivers came with documentation). Else, you may be stuck having to hardcode waits after each command.
If you wrote your own drivers, this is how you would send the command to set output 1 to 1 Volt:
V1 1;*OPC?
The V1 1 sets your voltage to 1 Volt. To tack on another command, you use the semicolon. The *OPC? command forces it to return send a "1." SInce the commands are acted upon sequentially, the power supply can't send the "1" until it is done processing the command to set it to 1 Volt. After that command is complete, the "1" is sent, you read the 1 out of the buffer and move on. This avoids issues where you pile on too many commands at once. I checked the manual and it supports this feature.

No power supply cable for second hard drive

Hard drive in PC is crashing mechanically. Want to ghost a second hard drive before first drive crashes completely. Bought duplicate of existing hard drive, but there is no power supply cable/connector for it. Have SATA plug, but cannot power up second hard drive. What do I do?
This question was solved.

LB1815, welcome to the forum.
If I understand your problem correctly, this is the connector that you need. It converts a single SATA power cable to two connectors. This allows you to connect two drives with on cable. There are many other brands available on Newegg. This is just one example.

Power supply dead? Can I get at the Hard drive?

I recently had a storm which blew one of my external firewire drives (it goes on but won't mount) and when I tried using my older G4 (Quicksilver, with OS10.3.9, and Classic) to boot up in OS9 and try my Norton Utilities, the G4 froze. It did it several times. I eventually pulled the power cord. When I plugged it back it, there was a spark (at the plug in point on the G4, not the wall outlet. Since then, it won't power up.
I tried booting it up in firewire disk mode and using my Intel MacPro, but no dice.
I did a search and have seen discussion on what sounds like my same problem. I hold the power button and the light goes on, but goes right off as soon as I let go.
I tried pressing the PMU; I saw a lot of discussion about the CUDA button but it seems these are one and the same thing. I removed the small battery and tried to get a replacement but have not succeeded as yet. Though I don't think that's the problem. It might be the power supply.
Anyway, here's my question: can I use the power supply and/or battery from an even older Mac, a PPC 8600?
And, whether or not that works, can I yank the hard drive from my G4, along with a second internal drive I put in (slave) in order to get data of it? (I'll give up trying to fix the G$ itself if I can just get my files off it.
*While I'm at it, can I take apart the external firewire drive that won't mount, and get at the files on that in some way. I tried Data Rescue ll but the drive still would not mount so that was useless.
Any help on any of these will be greatly appreciated. (Yes, I do have a nice big powerful UPS but the G4 and the external were no plugged in to it).
Thanks

Hi-
To recover your hard drives and data (including the external) get yourself a housing, and insert a drive, and move data to a different computer.
You'll want a firewire external housing with the Oxford chipset. I can recommend any of the FW or FW combo housings by OWC on the following page:
http://eshop.macsales.com/shop/firewire/add-ons-and-hubs/enclosure-kits
You will need a QS power supply-others won't work.
If you end up wanting a power supply for the QS, check eBay, or the following:
http://www.mac-resource.com/store.php?item=6612513.PART
http://hardcoremac.stores.yahoo.net/pog4quposu34.html
As for the battery, as long as it is the same 3.6v and form factor, any will do:

Power supply fan dead - help? (400mhz AGP G4)

Hello!
Unfortunately, my PowerMac G4, a 400mhz, AGP Sawtooth model, has a dead fan.
Over the last few weeks, I've noticed that my G4 has been running quite hot. I figured it was due to the hot dorm room that it's being used in. Then, I noticed that when it booted up, it would occasionally make a vibrating, or rattling noise - I figured the fan was wobbling. Since air was comming out of the fan opening at the top, I didn't worry about it.
Today, I used the "Temperature Monitor" widget to check the temperature of my SMART Hard drive (the G4 itself is not sensed). It was 133 degrees!!! This is the bay on the back-right, just under the CPU fan. I looked at the fan again - not much airflow. I pulled out a flashlight and pointed it in, and the Fan that's inside the power supply unit is dead.
So, how can I fix it? It's far far too hot, so it's not usable until I can cool it off. The first idea I had was to take a particularly powerful desk fan, and make a paper "tube" that connects both to the G4 and back of the fan - so it'll pull the hot air out. Needless to say, this is not a good log-term plan as it's easy to fall apart and will have leaks, but it works for now. I realize you can buy power supplies, but for ~$100, it's far too much for the old G4.
Second idea: The fan is inside the "non-user servicable" power supply, but it's also next to the back of the G4 - right inside what appears to be a panel that holds the power supply in. At the very least, I'd like to make sure that the cable is attached and not loose, but I have to open the back. Is that possible or safe? If so, can I replace the fan?
My third idea was to attach an extra fan to the inside of the G4, on the outside of the power supply - pushing in. Unfortunately, the IDE cable from the DVD drive is in the way, and there's not much room for a fan. Plus, there's no fan power supply. Is it possible to convert an ATA power plug (there are 7!) to a fan-power supply? I'd require a small circuit and a lot of resistors, obviously! If so, what would I need to do to convert it?
Thanks a bunch,
-Dan
15" 1.67 Powerbook G4 (Jan 2005), 400 mhz AGP Sawtooth G4 Mac OS X (10.4.8) 4G Clickwheel and 5G Vid iPods, 2G iPod shuffle

Thanks!
Interesting, this "Piggy back power adapter" will allow me to plug the fan into one of the ATA/IDE cables? Or do you mean the extra port on the power supply? (it has one plug for the outlet>G4, then another to support something like a monitor or similar) The G4 has a DVD burner, but no ZIP drive, so this is quite do-able if it uses the ATA power.
When you say "lower rear", do you mean at the bottom? Below the power supply, to the right of the PCI slots? If so, this is the inflow for the CPU fan! I can understand mounting it outside the current outflow-vent for the dead power supply fan, although I'm not sure the best way to proceed with attaching the fan.
Another question: what tools and supplies will I need? I may need to remove the plastic cover on the back of the G4 - the one that is outside the power supply - as there's a gap between the gray plastic and metal chassis that lets air from outside the machine come in. The screws for this cover use a funky, hexagonal screwdriver. If I need to take this cover off, what kind of screwdriver will I need? Also, should the fan not include screws/etc, what's the best method to attach it? Glue?
Secondly, to cut a hole in the G4, will I need some variety of drill? I don't have one, so i'll have to borrow one... Since there's nothing in the ZIP slot, I can run a cable out through here (assuming it's long enough), and make a new bezel to keep the airflow inside intact.
Ah! One other (somewhat related) question: my USB 2 card includes a power adapter, for use when several un-powered devices (flash drives) are attached. It works just fine with a flash drive and a small media reader, but it's slow to sense the drives - I think it's low on power. Unfortunately, this power plug uses the same variety of plug as the floppy disk drives found on many win-boxes - of which the G4 possesses none. Is there an adapter/cable for this purpose?
Thanks, this is a HUGE help, I appreciate it.

Power Supply blows a fuse, Ext Soundcard power outages, Time Machine.

Power Supply blows a fuse, Ext Soundcard momentary power outages. Time Machine won't backup.
Ok here's my setup
Mac Book Pro 13" APRIL 2011 latest firmware. 8GB RAM. Surge Protected mains connection..
M-AUDIO FIREWIRE SOUNDCARD AUDIOPHILE most recent drivers and powered by the MacBooks Firewire Out using a NEET Pro Lead,
The M-Audio has 2 x Firewire Ports and I take one to a 2TB 7800rpm Iomega iMedia Drive which daisy chains to a 1TB FireWire Seagate HardDrive and yes both are Pre Powered and formatted for Time Machines exclusive use.
The M-Audio Firewire module can be pre powered but isn't for this reason, the FireWire Out from the Mac IS pre powered, and I'm using a good quality NEET lead that powers the Audiophile ok over the last few months. I have been warned by the manual if I add a power supply to a pre powered firewire chain I could damage equipment, I'm now running the the screen as low as possible and the backlit keys off to minimise power drain, I also use an Acer 24" Monitor with a NEET DV mini port to HDMI adaptor and it's been working great but this must be more power drain on the power supply, One of the USB ports goes to an Native Instruments Maschine Sampler Module, the other goes to a Pre Powered 4 Port USB Hub and that has been fine, it has 1 Axiom 25 USB Midi Keyboard, 2 Pre Powered Hard Discs 1 Portable USB Drive. Now the problems started with Time Machine it can't backup and I get Hard Disk Unsafe Disconnects and Failed Time Machine Backups and Now my Soundcard does the same in that it momentarily disconnects and reconnects in a second, in Settings under ENERGY SETTINGS I've set hard drives to Never Shut Down, and the Screen also, it's been more frequent, then a fuse blows in the Power Supply without tripping up my Surge Protector Socket pfft! just great, well it is only a 3AMP Fuse in the Plug Socket but it saved my MacBook!, ok checks Mains, yes it's old, and I've started using the Central Heating alot now and when it turns on it could be causing a power surge, same with the FridgeFreezer. Things i've tried, on the Seagate pre powered FireWire Hardisc I have switched the Firewire lead to its second FW port, I got no errors with Time Machine this time, not 100% it's done yet, Soundcard resets in Logic 9 ****, I do have 2 lower quality Firewire Leads that go from the Soundcard to the 2 harddrives will need upgrading ASAP, thats next, I recon its time to upgrade the Soundcard as well for a Focusrite or similar as all my M-Audio Soundcards would literaly loose there minds on PCs and Macs, flakey drivers would just drop out of the Audiophole Firewire Card, more than I care to mention, so if that happens it could explain why the Time Machine drive drops out also, hmmm, and there was me thinking if I used a Mac it would all be ok. wrong. Would apreciate any qualified input, thanks.

Ok some updates I see, 6 in total including a firmware and security upgrades, also two Native Instruments Updates, Reaktor and Kontakt. I will be testing, this. Before the Updates I managed to peak the CPU load in Logic 9 and was only using 14 tracks, will need to bounce the Synth Plugs and drum tracks and run all the source samples from the Local internal drive a Hitachi 5400rpm drive hmmm :/ will experiment, anyway my Iomega FW drive froze up the Iomega Mac Companion is the correct name for it 2TB 7800rpm but it met it's match or was is the processor? Still sussing it all out. Firewire leads upgrade in effect. testing.. bleep. .

Power Supply Isn't Charging the Battery

This is a rather tricky issue. It's happened before, a few weeks ago, but it had seemed to work itself out and began functioning normally. As I was playing Neverwinter Nights today, the iBook went to sleep. I had the Power Supply plugged in whilst I was playing, assuming that it was charging the iBook. As it was going to sleep, I would try to wake it up only for it to sleep again after a few seconds. I managed to save and exit the game, and I noticed it's at 0%. So I unplug the adaptor and replug it. It continues to go to sleep, so I shut the iBook down.
After a few hours of fiddling with it and checking for information online on my iMac, I managed to get it to charge to about 15%. At this point, I turned the iBook back on and tried to get it to continue charging, but it's slowly been working its way back down to 8% or so ever since.
What's strange is that the 'ring' on the plug lights up as Orange, but it doesn't charge. I've noticed if I leave the iBook and Power Supply plug alone, the charge indicator will sporadically change between 'Battery Life Indicator' to 'Battery Charge Indicator'. It's not like it flickers between the two, but every few seconds or so, it will change from one to the other, but it still steadily drains the battery. I've tried resetting the PMU, but it doesn't seem to have done anything with the situation. I also tried to diagnose if my Power Supply is bad by reading Apple's information pages on it.
One of the troubleshooting documents shows images of bent metal rings on the connector. I looked at mine, and the metal ring is separated at the tip ever so slightly, nowhere near as bad as in the images. I can't figure out what's wrong. Could anybody give me some help?

I have the very same problem - you could try someone else's charger if possible
did not work for me though
If you get any luck could you forward the reply to [email protected]
cheers
