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
SWITCH2#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
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
https://tools.cisco.com/bugsearch/bug/CSCun41735/?reffering_site=dumpcr
And we can see workaround of this issue is HW workaround.
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.
Thanks,

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

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-

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."
http://www.cisco.com/en/US/docs/routers/asr1000/install/guide/asr1routers/asr1higV8.pdf
Hope that helps,

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)".

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.

Hi,
i have cisco 7603-S router with 1500W DC power supply. As per documentation, there is one input per power supply. I want to know the Electrical Cable specification (thickness of the cable in Sqmm)for the 1500W DC power supply, also type of lugs if required.

HP DV7-1020US (Power supply/battery issues) Please help diagnose!

Hi everyone,
I've read a lot of forum information about power issues/problems with this model laptop.
But have finally decided to post this question up here for some real HP support.
The problems started with the battery not being able to hold a charge. Shortly after, my brick started making a strange beeping
noise. I purchased a matching brick. I was able to get a few good minutes of charge and then every time after the laptop wouldn't power-up
at all. I'd just get flashing lights on the front (HD, Lightning bolt, Power). The lights would stop blinking after resetting the battery. I did some
research on laptop batteries and found that not allowing it to drain and then be recharged could cause it to go bad.
I purchased and received my new battery in the mail today. I am currently in the process of charging the new battery but have noticed
that the little lightning bolt light in the front of the laptop is NOT lighting up as it should when it's charging.
Is it NOT lighting up because both the battery and brick are after-market products?
I am going to allow the laptop with the new battery and brick to charge for 16 hours without attempting to turn it on.
I'm concerned that the system board or internal power supply might be having problems as well.
Has anyone encountered these type of power issues with this particular laptop?
Should I be able to run the laptop without the battery? That option has not worked for me.
Any assistance/guidance from you pro's out there would be greatly appreciated.
Thanks!
JUST WANTED TO ADD:
Laptop has been charging with new brick and battery for 8 hours straight and now, the battery indicator light is blinking.
I've tried removing the battery and reseating it but as soon as I plug the power back into the laptop the blinking begins again.

Hi people!
I started having the same problem with my 1020us. Battery isn't charging (it's 91% available, when the battery reaches 35% the laptop power-off). The battery led in front panel blinks too when laptop is plugged in to AC adapter).
Another problem with HP. I am so disappointed. =\

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.

Check the PS at the back, is there a light? If there's no light, then you need to RMA the PS as it could be faulty.
If there's a light on the PS, then you need to RMA the switch.

New battery not charging and no power supply reported

The battery for my G4 17inch powerbook had expired and a new one was needed. A brand new battery has been purchased and inserted into the machine. With the old battery the charger would go green then quickly amber before going off. With the new battery the light never comes on and in the battery info in the operating system it is listed as a new battery with 1 charge but the power supply section is not listing the power as connected. However with no batterys inserted the power supply will power and run the machine.
Can anyone offer any advise of something I could try or is it likely to be a dead laptop / charging circuit?
Thanks

There's 4 components in the charging circuit: power adapter, DC-in card, battery, and logic board. If you can run on power without the battery, and does not run when you insert a battery, that suggests that the DC-in board may be OK. So ... power adapter works, assume DC-in card works, new battery assume it works ... if you accept those assumptions, then you have a logic board issue.
