Odd power supply fault callhome emails on Cisco 2232 FEXs?

We recently enabled smtp callhome for our ucs pod a few days ago. Since then, we've received more than a dozen email bursts about power supply failures in each of the four Cisco Nexus 2232TP FEXs in our pod. In each case, we get a "Recovered" email within a minute or two, and we're not seeing power supply failure emails for any other devices within the UCS pod.
Here's a sample email burst from this morning, showing the subject lines within my email inbox:
System Notification from atl01-ucsf01a-A - environment:major - 2012-10-23 06:01:27 GMT-00:00 Recovered : Power supply 2 in fex 6 operability: inoperable

If we were seeing this from just one fex, I'd suspect a hardware issue. If any of the other UCS devices (rackmount/blade servers, fabric interconnects, etc) reported similar issues, I'd suspect a power feed problem within the DC.
But this has me baffled. If it helps, the UCS pod is running firmware 2.0.3c
Cheers,
Paul

Thanks Paul,
It is known ( cosmetic ) issue with power supply model.
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtz84683
The above is resolved in recent version of Nexus 5K switch software. New defect to port the fix to UCSM has been submitted today
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCuc87547
It will take a while to get published on web site.
Even though they are cosmetic, I would suggest you open a TAC SR with UCSM, FEX tech support and above bug IDs so that we can track the resolution.

C3750X - Power supply OIDs problems

Hello,
We are trying to monitor two stacks of CISCO WS-c3750X running IOS 12.2.(58)SE.
We can get the state of the power supplies, but after a power cycle or reboot of the switches the identifier of ONE of the Power supplies ALWAYS change. The OIDs for the rest of the PS do not vary. The problem happens in the two stacks.
Any idea or work around?
Kind regards
Mark

Hi,
I'm trying to determine if the issue addressed in this post is a match with the following symptom:
As you can see from the output below - the switch 2 power supplies appear to be healthy:
SWITCH#show env power switch 1
SW PID                 Serial#     Status           Sys Pwr PoE Pwr Watts

2B C3KX-PWR-350WAC     AZS161707FZ OK              Good     Good     350/0
Yet, the snmpwalk output shows a Sw2 PS2 power supply fault:
              snmpwalk -v1 X.X.X.X -c READONLY .1.3.6.1.4.1.9.9.13.1.5.1

SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.2035 = STRING: "Sw2, PS2 Faulty, RPS NotExist"
Do my symptoms match with the issue addressed in this post ?

Cisco power supply and APC UPS question

Good afternoon, I am running a 4507 with the Power Supples PWR-C45-2800ACV
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps4324/product_data_sheet09186a00801f3dd9.html
Can I plug this power supply into this UPS unit?
http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=SMX3000RMLV2UNC&tab=models

Jason:
My guess is that 2800w power supply is looking for two legs of AC in to make the DC stable on the switch.   I've installed a lot of 45XXx over the years but I never have more than 100 ports of active POE on them as most buildings have lots of computers and printers and a few VOIP phones and access points.
Now, those power supplies are pretty fault tolerent and well built. They can take (probably) swing voltage from 40-240V and 50-60Hz.    You can wire up the L6-30 into the TWLK cable and only have 20A of 120V on one leg from the output of your UPS.     You just have a single 30A hot, neutral and ground and a dead leg for hot into the power supply.   You use half the power supply.
The capacitors on the power supply will just have to absorb that and deal with it.   That's their job. Short term batteries.
One thing you need to realize is that you don't have to have two full-capacity 2800w circuits for the switch.   The 2800 is a reference number and that's based on a lot of inneffiencies in the entire system.
You've got at max a 2800w load and either 1 or two power supplies will feed it.    Two power supplies will be slightly less efficient than one but you're not pulling 5600w.
If you could, answer the questions above on the number of POE devices you've got and we can work a solution to solve the power to the switch and to your nodes.
You've got a lot of expensive, quality gear and the best solution isn't always to double up and re-buy what you've got.
I am going to recommend a metered PDU so that you can watch the amperage as when you approach the limit of what your wires can haul, you need to pay attention to the national electric code.
If you can PM me, do.

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.

Cisco Power Supply error

What does out of regulation limits means ?
1 red "OUTPUT FAIL," normally is off but illuminates when power supply outputs are out of regulation limits
Thanks
Rosa

Hi,
Seet this:
LED
Meaning
INPUT OK
AC-input power supplies:
•Green—Source AC voltage is OK. (Input voltage is 85 VAC or greater.)
•Off—Source AC voltage falls below 70 VAC, is not present, or the PEM is turned off.
DC-input power supplies:
•Green—Source DC voltage is OK. (-40.5 VDC or greater.)
•Off—Source DC voltage falls below -33 VDC or is not present at the PEM.
FAN OK
Green—Power supply fan is operating properly.
Off—Power supply fan failure is detected.
OUTPUT FAIL
Red—Problem with one or more of the DC-output voltages of the power supply is detected.
Off—DC-output voltages within acceptable margins.
Note For proper operation of the OUTPUT FAIL LED, systems with single power supplies must be configured with a minimum of one fan tray and one supervisor engine. Systems with dual power supplies must have a minimum configuration of one fan tray, one supervisor engine, and one additional module. Failure to meet these minimum configuration requirements can cause a false power supply output fail signal.
This is for 6500 switches but apply to almost all models.

Cisco 3850 Dual Power Supply - One No Response

Hey Guys,
I am getting multiple switches on my network showing "power supply failure" from Solarwinds.
I am running Cisco 3850s running v 03.02.03.SE cat3k_caa-universalk9 iOS, and they all have dual power supplies. When i do the sh env power, I get this output.
SWITCH1#sh env power
SW PID Serial#     Status Sys Pwr PoE Pwr Watts
1A PWR-C1-715WAC       xxxx OK Good     Good 715
1B PWR-C1-715WAC       xxxx No Response   Good     Good 715
SWITCH2#sh env power

1A PWR-C1-715WAC xxxx   OK Good     Good 715
1B PWR-C1-715WAC xxxx No Response     Good     Good 715
When I physically go down to look at the switches, they have green lights, so they are receiving power, but I keep getting the PSU failure alerts.
Do you think it is an iOS issue, and should I upgrade? Or has anyone else seen this?

Hi,
I think below Bug could match with your issue.
"power supply B is not responding" reoccurring on Catalyst switches

And we can see workaround of this issue is HW workaround.

Ciscoview Cisco 6509 VSS power supply LED indicators incorrect

Hello all
i am experiencing the following problem.
In the Ciscoview, the LED indicators of the power supply of Cisco 6509 VSS are represented incorrectly. All power inputs and fans are okay actually. however, in the ciscoview, there is only 1 green "INPUT OKAY" for each power supply. And "FAN OKAY" LEDS are off on Active chassis.
Any assistance would be greatly appreciated.

Cisco 12008 Power Supply Fan Tray Hot Swappable? 09/10/14

Hello,
I have a power supply fan tray [PART NO. GSR8-PWRBLOWER(=)—Power supply fan tray ] for a EOL Cisco 12008.
Q: This hot swappable while 12008 is online/powered on?
Thanks,
Kent C.

Typically, when "hot swappable" is mentioned, it means that these items can be replaced while not impacting the operation of the system.
When an optics module is pulled, traffic will be impacted. Depending upon the system's configuration, the traffic will need to re-converge.
The optics modules can be installed or removed while the system is powered up.
Hope this helps.

Is power supply 3k-X 715W AC hot swappable on Cisco 3750X?

Is power supply 3k-X 715W AC hot swappable on Cisco 3750X?
Thanks
Diego

Sorry, found the answer http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/hardware/installation/guide/3750x_3560x_HIG/HIGFRU.html
The power supply is hot-swappable. In some configurations, such as full PoE+ or power sharing mode, removing a power supply causes powered devices to shut down until the power budget matches the input power of a single power supply. To minimize network interruption, hot swap the power supply under these circumstances:
–The switch is connected to an XPS 2200 and sufficient power is available.
–The switch is in StackPower mode and sufficient power is available (Catalyst 3750-X only).
–The switch is powered by other switches in a power stack, and no active backup is in progress.
For the switch commands for displaying the available power budget, see the Catalyst 3750-X and 3560-X Software Configuration Guide.

Really odd behavior on startup and power supply

Hi there,
I am using MAC book pro and have X v.10.6 Snow Leopard installed couple months ago. One day several weeks ago, there was a long single beeping while I was surfing the internet and the system shut down by itself. After that, there is no way to boot the system up again. I tried to take the battery down and only have the magsafe connected to the machine, still no good to boot up the system. I tried everything I can do: reset SMC and NVRAM, change magsafe. Still no good. Last week, don't know why, I succeed in booting the system with the battery connected but it shown that the battery was in very low power. After that, the system never boot up again. I put the battery back and try to charge it via magsafe, no good, flashing alternatively with green and orange lights. I left the machine alone with magsafe and battery on for two days. Today, I tried to power on the machine, the familiar sound comes again, and the battery seems fully charged (I check by another MAC). However, there is a progress bar appears on the grey boot screen, after it has been fully filled, the spinning wheel seem runs forever and the system doesn't really boot up and no login box shown. Since my machine have both Mac OS X and windows 7 installed with bootcamp. I pushed down the power button and ALT to load the windows 7, no problem at all. But when I come back to MAC OS, same problem appears again. The system's startup process takes forever to finish. So
1) What's going on with the power supply? Since the problem lasting for too long, I assumed the logic broad must be damaged and I am ready to change a new one. But why it suddenly heals itself? And how come the battery fully charged? Weird!
2) How to solve the problem of 'forever loading' on startup?
I tried to boot from DVD by holding ALT and select DVD ROM on starting. The system shut down automatically after the DVD began to be loaded. And after that, I also tried to boot the system without DVD and the system automatically shut down in 10minutes.

Hi, Kurt. What you're seeing with the ringlight on the adapter is normal behavior for an adapter connected to a noisy or "dirty" AC power line. It's not an adapter fault, and is nothing to worry about except that it may impact other devices, such as your iPod, that are connected and drawing bus power when the adapter shuts down. See item 2 in this article for a brief explanation and suggested remedy:
http://docs.info.apple.com/article.html?artnum=302461
This is off the main subject, but since you mentioned it, I'm very interested to hear that your iPod Touch works normally when connected to your IOGear USB 2.0 card. Does the card draw bus power from one of your built-in USB 1.1 ports or from its own AC adapter, or is it supplying sufficient power all on its own to run the iPod?
Many people have posted here about troubles getting USB 2.0 devices, and iPods in particular, to work when connected to USB 2 cards in Tibooks. It seems that many such devices need more power than these cards can supply without auxiliary power. If the IOGear card can somehow pass along more power than others (which seems unlikely), or if the the iPod Touch doesn't need as much power as other iPod models (which also seems unlikely), those would be useful things to know.

Power supply of Cisco WVC210 Camera with batteries

I want to use my new WVC210 Wireless-G PTZ Internet Video Camera on my wheeled robot, so I would like to provide a separate power source for this camera.
Can I use 4 "D" batteries for it? They give 6 V DC, not 5 V as written on the camera.
I've measured the voltage coming out from the power supply, which came with the camera. In Switzerland it outputs 5.39 V DC.
I am afraid 6 V DC may damage the camera. Or is it OK?
If 6 V is not OK, then another possibility is 4 x 1.2 V DC researchable batteries. But it gives only 4.8 V DC.
Can camera be supplied with only 4.8 V DC? Or is it better to use 6 V DC?
Or I shall build DC-DC converter outputting exactly 5 V?
In specifications for the Cisco WVC210 it is written: "5V DC 2.0A switching power supply". But how tolerrant is the switching power supply? Will it work safely with 6 - 5.8 V?

I'm afraid we can't recommend using any power source other than the AC adapter included with the camera. Using anything else would likely void your warranty also.
