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 advanceHi ,
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-
Afroz

Kindly help me on how to fix this issue and what to do next?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,

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

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). -

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)".

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."

My HP DV 2025 TU model laptop start automatically as soon as i switch on power supply from power adaptor (Note : as my battery is totally gone so always need to start from power supply with power adapter)
OS : XP SP3
BIOS : F.39
Please help me by providing solution.Suspend has always been problematic under Linux. It seems to be hit or miss for the most part, but here are some things you can try:
Use an LTS kernel, tuxonice, pm-utils, etc. See Suspend and Hibernate
Try a different graphics driver
Tweak the driver module parameters or build your own driver.
Unfortunately I don't have experience with the radeon driver, so I can only give you ideas. -
When my macbook is fully charged, does the charger switch the power supply off, or does it continue to 'charge'?
(If I leave my laptop to charge whilst I'm out and it reaches 'fully charged' but is still switched on, will this continue to 'charge' my laptop? Or will it destroy my batter over time?)When the charge cycle completes, the pilot light on the MagSafe connector changes from orange to green. At that point the battery will be kept in standby mode, and the computer will be kept running with electrical power from the charger. If you want to keep an eye of where the power is coming from, get the latest release of the Coconut Battery utility: http://www.coconut-flavour.com/coconutbattery/

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!
MartyHi 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.

Do all Sun Servers come with switch-mode power supply?
I was posted this question by my customer and i was dumb founded. Can anyone help me on this? Thank you!
I'm not absolutely certain I understand the term "switch-mode".
If they are referring to a power supply that can auto-sense the input voltage, such as whether it can function with 115VAC versus 230VAC, then the answer is "maybe".
Recent workstation systems will have that.
Smaller server systems will have that.
Mid-sized servers may or may not have that.
An example: Sunfire V480's were auto-sensing, whereas the V490's require a nominal 200-240VAC.
Another example: the Ultra 5 and Ultra 10 workstations had power supplies that required you to slide a selector switch.
You are going to have to provide specific models, to get accurate answers.
Alternatively, just look it up in the Sun System Handbook. -
Redundant power supply for 3900 router series
Dear support,
does the spare power supply PWR-3900-AC= include a power cable?
best regardsThe 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:

I have finished installing 2 new BE6K's a week ago and they are in production now. I just received the secondary power supplies for both so can I install them while in production without causing service interuption or do I need to schedule down time to install?
Hi,
No you don't need to power down the server, just insert the new supplies.
