1410 ethernet uplink LED is off on power injector

I have a pt-to-pt wireless bridge consisting of two 1410 bridges operating over a 7 km link. It worked great until after approx. 2 weeks of operation it suddenly went down. The ethernet uplink led on the root's power injector was off with green injector status and ethernet activity led's. Tried power cycling, hard reset to factory defaults, and swapping injector and ethernet cables, power injectors, and radios with no luck. The consistent point of failure was the root bridge radio.
After receiving replacement 1410, the link operated for about 3 weeks, but now the same thing has occurred (dark uplink activity light with green status and ethernet activity lights on power injector).
Seems a bit unlikely that the same hardware error (if this was really the initial problem) would occur again. Any suggestions would be appreciated.

A 7Km link I'm guessing is outdoors. The same radio in the same spot only lasting a couple of weeks...my first guess would be weatherproofing.
How do you have the bridges set up physically?
Are they outdoors or do they run low loss cable up a tower? Are they grounded to the common earth ground? Lightning arrestors (Static Arrestors!) things like that.
What weather proofing has been done if any?

Computer does not turn on, power LED goes off when power button is pressed

My Pavilion 17-e078nr has stopped working, it will not power on. When you push the power button, the power LED next to where the plug is goes off and takes several minutes before it comes back on. I've tried removing the battery and get the same results and with the batter in and AC disconnected the power button does nothing. I've also tried the hard reset with no luck. As far as I know, nothing has happened to the computer since last time it worked. My two theories are either the AC power is bad, or there is a problem internal to the laptop. The AC power is providing the 19.5V, I measured it using a multi meter, I'm just not sure if it's providing the required wattage, or if the connection to the laptop is secure, it feels a little loose, but at the same time the LED comes on, so I know it's getting a connection. Only thing I can think to try is go to a store that sells this type of computer and see if I can use one of their power supplies to power my computer, and/or plug my supply into one of their computers. Don't know how willing any store would be to allow me to do that though. Any one have any additional thoughts or advise?

Hi! I have the exact same problem... the LED on adapter, is very, very dim when connected.
At first I tried connecting my macbook to my roommate's adapter and had the same problem. then tried taking out the battery, and still had the same problem. I did the same thing with my roommate's macbook, but hers did actually turn on! it operated without the battery. Figured out it was problem with mine.
I kept on trying combinations battery, computer and adapter. turns our that my battery (which I thought at first was the problem) charges perfectly on my roommates mac, but wont charge on mine. her adapter won't work either on my computer. What I've been doing is charging my battery on her computer, then placing it on my mac, and it works. only thing that won't work is the adapter.
Went to a mac store, and they told me that the problem was a small cable o wire that went from the Magsafe point into the mac and that the LED was very dim because no energy was being drawn from that spot because of this little wire being broken. they gave me the name of this wire... very technical stuff so, completely forgot cause I didn't have anything near to write on.
I'd like to know if anyone has gone through this same ordeal, and had this wire replaced without any problems. When it comes to opening up my mac, I'm a bit skeptical, since warranty is expired and wouldn't want for a solution to become a bigger problem.

Power & Wireless LEDs turn off on WRT54GX2

Over the past week, this has happened 6 times: the power and wireless LEDs turn off, the ethernet(1) and internet LEDs flicker like mad. While it's like that, all LAN and WAN traffic is disabled. It is connected to a DSL modem and the LEDs there appear normal. If I cycle power on the router, it returns to normal. I have not yet connected this behavior to any special events on my LAN. Does anyone have a suggestion?

You should Upgrade your router's firmware...
Download Firmware 3.70 MB...Firmware Ver.1.01.22...
Follow these steps to upgrade the firmware on the device : -
Open an Internet Explorer browser page on a computer hard wired to the router...
In the address bar type - 192.168.1.1...Leave the Username blank & in Password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Now reset your router :
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

Power LED Turns Off and pc Hangs

Hi,
During the last few weeks i've been having some problems with my system.
1. While playing games at a certain time (not always the same time) my power led turns off but my system does not turn off. Instead it just runs very slow and any audio, software and the mouse pointer is constantly lagging until i restart it.
2. After problem 1 while restarting it takes a lot of time to shutdown and hangs at the Windows is Shutting Down screen, so then i'll have to press the reset button.
3. The system also rarely instantly turns of without going trough shutdown and even more rarely it resets while scanning the RAM at the BIOS.
Thanks in advance for all your help!

Yeah well my PSU is ok cause i just baught a new one and i hope i dont have a short.
Do you think that maybe the graphic card isnt compatable or something cause these things started happening when i changed my graphic card and this only happens while i'm playing games cause not even if i have loads of software running it still wont do it.
And does anyone know of software which i can use to check my RAM?
Thanks.

UMI "V" LED off when power is applied

Hello all,
Has anyone seen the "V" LED go off after a successful power-up of a UMI-7744? We power our encoders from the UMI so we lose feedback when this failure occurs. Both "Viso" and "V" are powered from the same supply at 24v. The "V" LED goes off ("Viso" stays on) and power is not supplied to the individual axis connections as it should be, when I measure the voltage supplied to the UMI (Viso & V) it's at 24v as expected. I'm guessing that the UMI has an over-current trip inside and switches power off when too much current is demanded, then does not switch on again until a power cycle. Or maybe we have a faulty UMI? Has anyone seen anything like this before?

Hi Martin
If you read the UMI-7774 manual, which is the device I assume you were talking about, in chapter 2 Installation the following is listed:
Required Materials
The following items are necessary for installing and getting started with
the UMI-7774/7772:
UMI-7774 or UMI-7772
24 ±10%; VDC power supply (10 W minimum)
5 to 30 V isolated power supply (10 to 60 W minimum, depending
on I/O requirements)
From what you have written in your message I would suggest you get another power supply between 5-30V and attach that to Viso.
Hope this help
Kindest Regards

Problem in Cisco 1410 Bridge - Install LED in solid amber all the time

Hi, have anyone encountered during power up of Cisco Aironet 1410 (with integrated antenna), the Install LED status is solid amber all the time?
At Bridge LEDs
Install LED - solid amber
3 LEDS - none
At power injector
Uplink - Off
Injector - Blinking Green
Ethernet - Off

Two things.
1. Did you assign the role of that bridge? Root, non-root, etc.,
2. Check for "install" mode on the GUI itself and that may lead to finding the problem.

IMac 20" won't start. l led 1 is on, but led2 flashes, led 3 off. Why?

My wife's original iMac 20" suddenly today went fans full on. She turned it off by holding the on/off button for some time. Now it won't start up. With the back off led 1 if on, and led 2 is flashing. I've found reference to led 2 off and led 2 on, but not flashing. I've reset the SMU several times and the led went off, but after several seconds started flashing again. Can anyone suggest why?

It's likely that your power supply has failed, but ake sure that there is no dust clogging the fans or vents.

Power Injector AIR-PWRINJ1500-2 LEDs Continously blinking

Hi,
I am facing a strange problem with the AIR-PWRINJ1500-2.
At times the injector behaves perfectly fine but once Switched Off & again Powered On, all 3 LEDs, never become stable & blink continuously.
Has someone seen such a behavior ? Pls, share.
Thanks in advance.

Hey Ahmed,
My understanding is the power injector is not supported for the 1552CU and your only powering options are the following:
1552C/1552CU
• 40-90 VAC, 50-60 Hz, quasi-square wave, Power over Cable
• 12 VDC

All of a sudden, the radio signal LEDs went off and node went dead

In order to change the I/O variable data type of my node from single to array of single, I simply press and hold the rest button on WSN-3202 for 7seconds. At the end of it, the radio signal LEDs went off and node went dead. All attempt to bring it back to life proof abortive. What should I do?
Blessing

Hi Blessing,
If you've tried everything to get it working, including a fresh set of batteries or direct power from an adaptor, then you should contact your local NI branch regarding the repair process. The contact information for your branch can be found on http://sine.ni.com/apps/utf8/nicc.call_me.

Led On/Off .control

Hi Folks.
I am having trouble keeping certain Led's on at certain times. The power on and off turn eachother on and off as required. However when I press any of the other buttons the Power On/Off Led goes off. I have set up an event structure to handle the different button presses. Is there a way to keep the current value when the other buttons are pressed?
Also but not very important now. Is there a way to implement the led's in the actual buttons themselves without having to use extra components?
Thanks,
Mark.

The problem with this is that I need the On button to turn the Off Led off and vica versa. I need off and on to influence on another.
My comment was just to note that there is another solution after what paul_cardinale mentioned if you don't need mutliple event cases to interact with the indicator(s).
MarkGreally wrote:
Is it possible to set them up to hold previous value if unwired or something like thta?
No, but you can store values in memory in places other than indicators. The While Loop structure supports a shift register for this.
A common solution to your situation is to save state information on a shift register of the loop and update indicators from that. For example:

Now it won't start up. Have a Replacement on order. Is there a bigger issue or does a battery need to be in the compartment to boot up? Appreciate any help. Thanks.

Working battery needs to be in for the computer to function.

Hi Fred,
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
