Cisco Switching/Routing :: 2960g-24tc-l Internal Power Supply Pinout / Voltage Check

Feb 25, 2013

I had a bad power surge yesterday that took out a 2960g switch and the APC UPS that it was connected too. when plugged in the fan comes on and the syst light stays amber and the rps, stat, duplex. and speed light stay lit and the port lights for ports 21-24 stay lit. plugging it into the console on boot I cant even see rommon, so i dont think its even booting. I would like to find a pinout and voltage guide for the connector comming off the power supply so I can check the voltages coming off the power supply to tell if it is a bad PSU or if it took out the main board.

Cisco Switching/Routing :: 2960S - Internal Power Supply Show Unavailing When Running Off RPS?

Feb 13, 2012

I have a 2960S connected to an RSP 2300.  The 2960S is currently running off of the RPS, and I would like to switch it back to the internal power supply.  Can I just run "power supply 1 on"?  Will this cause the switch to reboot?  Also I am concerned because when I do a show env power it shows: [code]
 
 Is it normal for the internal power supply to show Unavail when running off RPS?

Cisco Switching/Routing :: Stack-power 3750x / FRU Power Supply Is Not Responding

After stacking two 3750X switches, with four equal power-supply's, with StackWise and PowerStack , still got the next message every few hours %PLATFORM_ENV-1-FRU_PS_ACCESS: FRU Power Supply is not responding (gn4m-rt1p08-04-2)( note that the message revers to the second switch in the stack ) although the stackwise and powerstack on the switches is oke and are working correctly. !
 
Config  : Stack-power in power-sharing mode/strict With CLI on the switch : All the power supply's and stack-power details, prio look OK.
 
Only: LMS prime /inventory/cisco-view/configure/power supply status  result :  some power supply's are marked as disabled.with the command  > power supply 2 slot a off/on I manage to get the status back to "normal", but after a few hours some power supply's are again marked as "disabled".

Cisco Switching/Routing :: 3750X Stand Alone Secondary Power Supply Act As Pool Of Power

Apr 4, 2012

In a stand alone 3750x switch configuration, can the secondary power supply only act as a redundant power supply (active/standby), or can it become a "pool" of power similar to power sharing mode for StackPower (somewhat active/active)?  I understand there is no stack involved here but I'm curious if this functionality is possible.

Cisco Switching/Routing :: Finding Specification For 3750x PoE Power Supply?

Jul 11, 2012

Looking at the specs for the 3750 power supply - is the WS-C3750X-48P-S model with the 715W power supply referring to the amount for both power supplies per switch or just one power supply per switch? Meaning, is the 715 a accumulative number or, just the watts of one power supply. I would like to purchase a 3750x PoE switch with redundant power supplies. If this model is not the correct one?give me the model that offers 48 port PoE with redundant power supplies?

Cisco Switching/Routing :: 4506E Switch Power Supply Upgrade

Dec 8, 2012

I would like to check if it may be possible to hot-upgrade/swap the 4506E power supplies? Based on the configuration guide; I have summarized the steps as follows:

1. Switch has 2 existing power supplies to be upgraded

2. Remove right side/bay 2 power supply and install new power supply

3. At this point; the new power supply will be in err-disabled due to different power supplies on the switch

4. Remove the left side power supply and install new power supply

For item 4; during the removal of the old power supply in bay 1/left side and installation of the new power supply; I am wondering if the switch would lose power even though the new power supply is installed in bay 2?

Cisco Switching/Routing :: Power Supply Compatibility From 4500 To 6500

can I plug power supply from 4500 to 6500? more specifically we have power supply PWR-C45-1300ACV. And we need to place some power supply to 6500, which has only one active module. So 1300 should be enough for it. But we dont know if they are physically compatible, if it is possible to plug. I didnt find this power supply to be officially?

Cisco Switching/Routing :: 7606s Power Coming From Single Supply

Apr 6, 2012

Having a strange issue here with an 7606-s chassis equipped with two sup720's, and two regular line cards. There is only one power supply, PWR-2700-AC. I recently builded this setup and powered it on last week for the first time. It ran fine for about 20 minutes while suddenly the chassis powered down.
 
I've checked the back of the chassis and noticed that the power supply had it's 'input ok' and 'power fail' led lit. I toggled the power switch and waited half an hour to power it on again. This time only 1 minute of joy. My first idea was the PSU due to the power fail led so I had it swapped by the supplier for another. Unfortunately, when I powered it on today, it didn't change a thing, still unexpected power downs.
 
So I've checked the following documentation: [URL] and followed the suggestion to power the chassis on without any modules in the slots. So I did that and it ran for 8 minutes only. However, the fan tray did respond properly when I removed the small thermal module in the upper right by increasing the fans to full speed.
 
Following above documentation, it points to the chassis (there is not much left). Now the real question comes, isn't there anything else that could be the cause of this?

Cisco Switching/Routing :: Catalyst 3750X With PoE Secondary Power Supply Options?

Jul 21, 2012

When quoting a Catalyst 3750X with PoE (WS-C3750X-48P-E) the Dynamic Configurator Tool allows to include as the secondary power supply option the Catalyst 3K-X 350W AC Secondary Power Supply (C3KX-PWR-350WAC/2), but the default included primary power supply is the Catalyst 3K-X 715W AC Power Supply (C3KX-PWR-715WAC). My questions are the following:
 
1. Will this combination of power supply work?

2. Will the C3KX-PWR-350WAC/2 be able to power up the switch if the primary power supply of 715W fails?

3. Will the PoE will be lost if the primary power supply fails and only the secondary power supply of 350W keeps working?

4. If this secondary power supply of 350W is not suitable for PoE, why it is available as a secondary power supply option in the Dynamic Configurator Tool for a PoE switch?
