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.

C3750X get power supply errors

Hi, I got a problem with some phones connected to a C3750X-48PS. Phones are Polycom SoundPoint 560. Ports most critical: gig 1/0/9 & 1/0/31.
Actually, the C3750X belongs to a stack, with the IOS: 12.2(55)SE3. The environment conditions: power supply working ok, temperature level: ok. (show env all). Physically the LEDs are in green, and the room does not have temperature issues.
Also, the phones present a humming noise (high pitch). The noise keeps happening even if the phones are plugged in other ports of a stack. It was attempted to connect the phones directly to the stack ports instead of the ports in the cubicules, and the issue keeps happening.
The Stack presents also sudden fan to spin up / spin down for a couple of minutes, and within a couple of minutes from working on and off.
Customer has another facility with the same switches but with IOS12.2(55)SE1, in there the same phones were tested and they are working fine.
A reboot was performed, but now the C3750X show these messages:
%ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi1/0/9: Power Controller reports power Tstart error detected
%ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi1/0/31: Power Controller reports power Tstart error detected
Thanks!

I've found it! In case anyone is wondering, a lot of server information is available by querying with the iLO xml tag "GET_EMBEDDED_HEALTH".
This returns, buried way down in the results, information about power supplies (section POWER_SUPPLIES).
While there doesn't seem to ask for just information on the power supplies, this works!

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.

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.

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 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

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.

Always getting errors when trying to control YOKOGAWA 7651 power supply on Labwindows/CVI

Hi,
I'm trying to set the voltage on the YOKOGAWA 7651 power supply through labwindows/cvi. I've set up a numeric slide on my userinterface with callback function "yoko7651dcvolts" and constant name "YOKO7651DCVOLTS".
I always get this error when I run my program:
"FATAL RUN-TIME ERROR: "DcSource.c", line 53, col 65, thread id 0x00001F3C: Invalid argument type: found 'pointer to double', expected 'pointer to int'."
This error points to the third argument of the GetCtrlVal function below. The program/compiler wants me pass the variable "yoko1volts" as integer, but I want to (and should) be able to set voltages as floating numbers.
Plus, even when I declare "yoko1volts" as integer, it stills doesn't work. All I get is zero, zero, and zero...on the power supply meter everytime I press the numeric slide.
This is the section of the C code that is problemic:
int CVICALLBACK yoko7651dcvolts (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
double yoko1volts;
switch (event)
case EVENT_COMMIT:
GetCtrlVal (yoko76511Panel, YOKO7651_1_YOKO7651DCVOLTS, &yoko1volts); // to read the values entered on the numerical meter on the user interface
yk7651_set_volts (yoko76511Panel, yoko1volts); // set the entered values as voltage on the instrument
break;
return 0;
This is the related h-file:
#define YOKO7651_1 4
#define YOKO7651_1_YOKO7651SWITCH 2 /* control type: binary, callback function: yoko7651switch */
#define YOKO7651_1_YOKO7651DCVOLTS 3 /* control type: scale, callback function: yoko7651dcvolts */
Please help, how can I fix this issue?
All the drivers (including the YOKOGAWA 7651 power supply) are properly installed and mounted. As a matter of fact, I can successfully turn the power supply on and off with the code below:
int CVICALLBACK yoko7651switch (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
int yoko7651switchstate;
switch (event)
case EVENT_COMMIT:
GetCtrlVal (yoko76511Panel, YOKO7651_1_YOKO7651SWITCH, &yoko7651switchstate);
SetCtrlVal (yoko76511Panel, YOKO7651_1_YOKO7651SWITCH, !yoko7651switchstate);
yk7651_output (yoko76511Panel, !yoko7651switchstate);
break;
return 0;
It's just setting the voltage on the power supply that is very problematic. Any help is appreciated...Thanks.
Solved!
Go to Solution.

I second Al opinion of a disconnection between the UIR and the variable that holds the panel handle.
As a side note, I noted that the problematic line is reading the value of the controll whose callback is executed:
#define YOKO7651_1_YOKO7651DCVOLTS 3 /* control type: scale, callback function: yoko7651dcvolts */
int CVICALLBACK yoko7651dcvolts (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
double yoko1volts;
switch (event)
case EVENT_COMMIT:
GetCtrlVal (yoko76511Panel, YOKO7651_1_YOKO7651DCVOLTS, &yoko1volts); // to read the values entered on the numerical meter on the user interface
yk7651_set_volts (yoko76511Panel, yoko1volts); // set the entered values as voltage on the instrument
break;
return 0;
In a situation like this, I would try using GetCtrlVal (panel, control, &yoko1volts); instead, that should get rid of all problems in panel handle / control ID.
Despite this solution is working, in any case I would deep into the problem as an incorrect panel handle can lead to erratical behaviour in other places of the program.
Proud to use LW/CVI from 3.1 on.

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.
