PoE issues Summit x460


Stack consists of the three Summit devices: two x460-48p & one x460-24p (#'s 1, 2 & 3 respectively)

When I try to connect a POE device to the 2nd switch, there is no power except for 2 of the 48 ports. The other two switches in the stack are fine. The command "show inline-power slot 2" returns a response "Timeout occurred while retrieving information from hardware." Switches #1 & #3 respond "properly" with their respective power info.

I have rebooted, in turn, each slot. I have also rebooted the stack-topology with no change to the error message noted above. Everything looks & operates fine when a non-PoE device is connected on switch #2.

Despite 2 of the ports delivering power on slot-2, "show log messages nvram" output contains this error: Slot-2: poePlusInit: Initialization failed

Stack, version, and switch output included below.

Any feedback is appreciated.

You will need to contact GTAC to proceed further with this issue. This switch may need to be replaced if there is valid entitlement/warranty. Here is an article that provides more information:

Based on the link, will any of the commands below cause a disruption of service?
  • run diagnostics extended
  • run diagnostics extended slot n (if running on stack or Black Diamond)
  • show diagnostics

run diagnostics extended will take down the network and reboot the switch. But it will be necessary for GTAC to begin the RMA process.

I believe I know this answer, just dotting the i's and crossing the t's. Stack topology is a Ring. If I "run diagnostics extended slot 2", will the remaining slots continue their normal operation?

Or am I better off running diags on the whole stack?

The rest of the stack should function normally. If you would like to be safe you can disconnect the stacking cables from slot 2 and login manually to run diagnostics.

Diagnostics will cause an interruption on the switch you run it on. It is best to do this during a maintenance window.

What is the average time for the extended diagnostics to run on a specific 48p slot?

I would allot about 15-20 minutes for the diagnostics to run fully.
Guessing this will be a GTAC call...

Thanks for the assist
