3845 Router redundant power supply question

Is it possible to swap out a bad redundant power supply on a 3845 router without powering down the router?

The FAQ at this URL indicates that they ARE in fact hot-swappable. Please review it here, under "System Power (AC/DC)".

Adding Redundant Power Supply

Hi,
I was wondering if I am able to add a redundant power supply to an asr 1001 router that is in production without losing connectivity or causing any diruption to the Users - is it hotswappable?
Thank you, Pat.

Hi Pat,
Yes, the power supplies are indeed hot swappable. Check out the quote from the following link :
"All system components are hot-swappable. They are designed to be removed and replaced while the
system is operating without presenting an electrical hazard or damage to the system."

Monitoring 3750x and 3560x Redundant Power Supply and Fans

I need help for monitoring the redundant power supply of my switches (3750x and 3560x)
I have configured my snmp on my switches and is able to monitor interfaces, temperature and etc.
The problem is when I am monitoring the redundant power supply and fans.
I am using two Cisco C3KX-PWR-350WAC Modular Power Supply per switch.
The OID I use to monitor the PSU are the following:
Power Supply 1
.1.3.6.1.4.1.9.9.13.1.5.1.3 Instance: 1003
Power Supply 2
.1.3.6.1.4.1.9.9.13.1.5.1.3 Instance: 1004
When I do an SNMP walk, the value is showing (1) which means normal.
When I simulate a power outage on power supply 1 or 2 by unplugging the power source, the value doesn't change and is still (1).
Values: normal(1), warning(2), critical(3), shutdown(4), notPresent(5)
As for the Fans:
When I remove the fan module, I am able to get a notification that the fans are down, but when I plug back the fan module it is now using a different instance.
Below is my config for SNMP:
snmp-server community XXXXXXXXXXXXXX RO
snmp-server location XXXXXX
snmp-server contact XXXXXX
snmp-server chassis-id Cisco3560X
snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart
snmp-server enable traps transceiver all
snmp-server enable traps tty
snmp-server enable traps license
snmp-server enable traps cpu threshold
snmp-server enable traps syslog
snmp-server enable traps vlancreate
snmp-server enable traps vlandelete
snmp-server enable traps port-security
snmp-server enable traps envmon fan shutdown supply temperature status
snmp-server enable traps errdisable
snmp-server enable traps vlan-membership
snmp-server host X.X.X.X version 2c XXXXXXXXXXXXXX
Note: This problem is the same for all of my 3560X switches and 3750X switches. I am not sure if I am monitoring the wrong OID.
Thanks in advance

Hi ,
You are running an old IOS code , definitely you are hitting a BUG .
there is no workaround or I would say unfirtunetely you will not be able to get the correct power supply status via SNMP.
you need to use command line for this.
I mean "show env all "
**** if you want to know the Excat BUG that your code is hitting ,please contact TAC.
Thanks-

Hi Senthil,
What are the LED status on RPS. It looks like RPS may have gone faulty. How many switches are connected to it? Possibly a reset of RPS could fix this issue, else replace it.

Does "dual power supply" mean "redundant power supply"?

Does Cisco7301 "dual power supply" mean "redundant power supply"?
If unplug one power socket, 7301 continues operating?

On a 7301, I believe it does act as a redundant power supply, and this is often true for many Cisco devices with dual power supplies, but there can be exceptions. For example, on the 6500 chassis, you might use dual power supplies in combined mode, i.e. failure of a power supply would leave the chassis short of necessary power. The 3560X/3750X might also have insufficient power if a power supply fails when running on two (this issue may arise when using PoE).

CNA & "switch redundant power supply"

Just configured trunking between these switches:
2950T-48-SI
3508G-XL
3548-XL
The traffic appears to be flowing correctly through both the default VLAN and also my additional VLAN.
Now, ALL of the 2950 switches on my network display this message: "switch redundant power supply failed" when I connect to them using the Cisco Network Assistant.
Seems like the error message must be related somehow to the VLAN configuration I did.
In a nutshell, I configured all connected Gigabit ports this way:
switchport mode trunk
switchport trunk encapsulation dot1q
I only configured SOME of my switches for the trunking and additional VLAN - must all of them be configured the say way, even if I don't anticipate needing the additional VLANS on those switches?
Thanks, Susan

Hi Susan,
Do you have redundant power supplies connected to the 2950s?
If not, you are probably running into a cosmetic bug, CSCee96721.
We can confirm this by issuing a "show env" in the CLI.
You should see something like this:
"switch#sho env all
FAN is OK
Internal POWER supply is OK
RPS is NOT present
RPS is FAULTY"
Note that the last line indicates that the RPS is faulty, even though the line above it indicates that no RPS is present.
If that applies to you as well, then you are hitting this bug. CNA is polling the same information, which is why you are seeing "switch redundant power supply failed" in CNA.
The fix is in 12.1(22)EA3 and later.
HTH,
Bobby

Redundant Power Supply

Hi everyone,
I would like to know if the SG500-28 supports redundant power supply (means 2 power inputs) ?
Thank you.

Thank you for your response Mr. Lewis.
In fact, I need to know either if the native hardware of the SG500-28 switch supports the power redundancy or not.
P.S : I don't really know when did I create this account, but it is certain that I was harry So thanks for reminding me to change this awesome nickname

975X power supply questions

Hello,
I'm building my first box(!) so I am a bit of a newb with some things, but otherwised an experienced tech. for the life of me I can't figure out power supplies.
My system:
975x Platinum mobo (I don't think it's v2)
Intel Core 2 Duo 6600 CPU
HIS ati 1800GTO IceQ PCIe x16 GPU
2 x 1GB ASUS PC4200 sticks
2 x 250 GB harddrives
as you can see I am building a good but not blazing machine. Here are my power supply questions:
1. what model power supply exactly does this mobo need? the 8pin CPU is an EPS12V model? would any ATX12VEPS work, or does that 8pin need to be a dedicated 12V?
2. my GPU has a PCIe power slot, and the mobo has a molex power connector for the PCIe. Do I use both? Do I just use the one on the card?
3. does the CPU require any other funky new technology in power that I need to look for?
4. (is it just me, or does is kind of information very hard to find? I can't find any details in the manual
I went ahead and bought as Ultra 500W X-finity with the 8-pin, PCIe x2, dual 12V rails. hopefully it will be fine.

i dont know why they put 8
but check out this pic:

there is cover on 4 of the pins so they are not used.

Redundant power supply for 3900 router series

Dear support,
does the spare power supply PWR-3900-AC= include a power cable?
best regards

The 5B01 backplane itself requires no current, just the individual modules. 1A should suffice well then. Personally, I use separate low noise linear regulated supplies for the backplanes in my designs.
Here's a couple links to assist:

Adding third party video card to P700 - no power connectors? New Power Supply Question...

Hello,
I have a new P700 30A90012US with a 650W PSU and that didn't come with a video card. I am planning to use it as a DAW and for occasional gaming via a dual boot.
I wanted to put in a third party video card like a nVidea 970 but there aren't ANY connectors for video cards that I can find inside. The monitor I have is a 3440x1440 monitor. I have ordered a second 2609 Processor and RAM from Lenovo and have the following questions:
Once I install the second processor, how much wattage for a video card is available to me?
I understand that the 3rd party video card isn't supported but how do I attach power to it?
If it is required that I have to replace the 650 power supply with an 850, does it come with the required cable? I only see a 4 pin connector on the mobo that is unused (and I believe it is for additional hdd)
I tried searching but I am at a loss.
Thanks,

Your config isn't really power hungry (and the 85W CPUs help a lot). Though technically outside of the official spec, I think you could easily go to a 225W card for graphics if you had the connectors available to support it. I'll double check the current when I get a chance, but it's probably really low risk if you want to convert your single 6-pin connector to dual 6-pin or a single 8-pin (via a dongle) to get to 225W TDP if you wanted to.
The PSU design is very modular, but unfortunately it's the aux power cable drops that kept it from being an easy field upgradable part. I always recommend that people buy the larger PSU if they ever think they'll be doing any upgrades in the future just to make sure they are covered.
And like I said if you're comfortable working inside the system, it's not impossible to upgrade that cable drop on your own if you want to go up to the 850W. You'd have to get the cable and PSU, but after that it would require removing the motherboard and PSU, cutting some cable ties and routing the new cable, then getting everything routed correctly such that the motherboard reinstalls cleanly.

Cisco 3850 Redundant Power Supply Reporting Issue

We have deployed several Cisco 3850's. Several are showing the following symptom
ont2-tc3-es01#sh env power
SW PID Serial# Status Sys Pwr PoE Pwr Watts
1A PWR-C1-715WAC DCB1702G0QU OK Good Good 715
1B PWR-C1-715WAC DCB1702G0G6 No Response Good Good 715
Every single switch at this particular location has the same status on the B power supply. The problem was there on the previous code level (3.2.2) and we recently upgraded to 3.3.5 to resolve some SNMP bugs on the switches we also expected the latest Assurewave version to fix this issue also. So couple questions:
1. Anyone else seeing this?
2. Anyone found a fix for it?
Thanks!
Marty

Hi Zabeel,
                   I did talk with TAC - per the engineer there are two bugs that cause the issue and one was fixed in 3.3.5 - so we upgraded all our 3850's to that code level. Unfortunately for us, that still didn't fix the issue. TAC suggested that it may be fixed in rev 3.7.0, but that has not officially been confirmed by Cisco's developers.
         We're waiting for the official "fix" before going through another round of switch upgrades.
        TAC did suggest reseating the power supply if you still have the issue after the upgrade to 3.3.5 - but that's not really an option for me since my switches are geographically spread out.
   HTH

Power supply question or Firewire issue

Hi
I have a workhorse Dual g4 with three internal video drives, three self powered Firewire drives and an internal Gina audio card. Recently I added a USB2 internal card and swapped my Viewsonic LCD for an Apple where the power is coming off the video cable. For the last 2 days my Firewire drives got balky. They mount but when I try to open them I get the interminable spinning beach ball. So far I am able to connect the FW drives to my G4 laptop and they seem to mount ok.
Am I asking too much from the power supply or is this a fair load?
Could the Firewire have failed.
Last week I had a high whine and lockup (heat related?) It's been funny ever since.
Is there an app that gives the status of the hardware?
Sorry lots of questions
Thanks
Enio

The XServe power supplies (like most modern systems) are rated for 100-240V, so will accept any input voltage in that range.

P6N SLI / power supply question

I have a question to pose to the experts. I am building a computer for a friend. He brought me the parts to work on. The motherboard is the MSI P6N SLI and the power supply he brought me is a KWi KingWin Model AP-450 with the following specs:
+3.3V - 22A
+5V - 35A
+12V - 15A
-12V - .8A
-5V - .5A
+5VSB - 3A
Total - 450W
The system will contain 2 hard drives, one Seagate Barracuda 7200rpm 80GB SATA the other a Seagate Barracuda 7200rpm 40GB IDE.
It will also have a SATA DVD burner and a XFX GeForce 8600 video card which does not have a power input.
CPU is an Intel 925 dual core chip.
In your opinion, will the 450W power supply be good enough to keep this system stable?

Total watts is pretty useless these days. It is more important that each rail has current reserve beyond what is attached to that rail. A poster in another thread had a 1000W power supply with 4 rails that he spent nearly $300 on. Each individual rail was spec-ed lower than the minimum for the motherboard almost all the excess power was on the drive connectors not the motherboard connectors and the 4 +12V rails were not helping the motherboard since only 1 rail was supplying the +12V to the motherboard. So in this instance a 500W supply that only has 1 rail that is 25A on the +12V is more powerful than the 1000W supply. In this case, the 500W power supply would be fine for powering up the motherboard alone, that particular 1000W supply would not.
Lesson here:
You can't just throw Watts at your system without determining where those Watts are going.
It only takes 1 leg of your power supply to be too weak, for the existing setup, to make things act weird. Doesn't matter how much reserve power you have on the other legs. 1A too weak and any chip can power down in the middle of things doesn't matter if you have a 2000W supply that cost $1000.
The components in your computer do not care about how cool your power supply looks. They don't care if it has LED fans or UV connectors or braided sleeves. It doesn't matter how much it costs. Once you find a list of power supplies that will work for your system, then look for adequate cooling, enough of the right connectors, etc. The 2nd to the last in the decision process should be glossy paint and lastly the price. Of course you may want to purchase that clear case power supply with 3 color LED 120mm fan. It may just be a conversation piece sitting on the shelf if it won't work in your system.
Good examples:
The first one may in-fact be the best one for a particular motherboard. The last one may not even power up a basic quad core system business workstation. You must research what you are buying. Don't just look at how cool it is.
This one has 25A on the single +12V rail. 550W
http://www.newegg.com/Product/Product.aspx?Item=N82E16817170011
This one has 16A on the +12V1 and 18A on the +12V2 rails. 500W
http://www.newegg.com/Product/Product.aspx?Item=N82E16817148003
This one has 7 +12V rails, several of them at only 20A. 2000W has 2 power cords and I want to know what case it fits in. I see feet on it and they are calling it a modular supply. There are other ways of doing things. Not everything has to be forced into one system.

W510 135w Power supply questions? Differences...

Hi,
Recently I purchased a new 135w power supply for my w510 off of amazon. (http://www.amazon.com/gp/product/B0038LYW8O/ref=oh_details_o00_s00_i00)
When I got the power supply in the mail I plugged it in. Within only 5 minutes it got VERY hot and then just stopped working.
When I compared it to my old power supply I noticed slight differences. I attached some images below. Can someone give me some insight to this? Did I get a knock off or incorrect power supply?
The left side is the new one, the right is the original shipped with my laptop.
Link to picture
The first thing I noticed was the icon on the bottom left is yellow on the new one, it's not on the original. What does that mean?
Also different sized text, PIN's and icons in the center.
The other big difference was the plugs that go into the power outlet. Again... New on the left, original on the right.
Link to picture
I have no idea if anything makes a difference that I mentioned. I'm just trying to figure out if I should exchange the one I got for another or get a refund. Hopefully someone can help. Thanks!
Moderator note; picture(s) totalling >50K converted to link(s) Forum Rules

I don't believe it's a copy.
Both the different FRU numbers are listed on this site and match the 135W adapter FRU numbers. I would suggest that the difference is source manufacturer, Lenovo doesn't rely on one source for particular components alone; it would be too risky.
