So how many of you have done a "show power" and looked at what your fan module is reporting back to you?
We recently updated a number of our older 7606 chassis to the newer 7606-S chassis and upgraded the fan assemblies as well.
When we performed a show power on the new boxes they reported our fan assemblies as being the older FAN-MOD-6HS units instead of the actually installed FAN-MOD-6SHS units.
I am curious if anyone else has seen or experienced this to date? We have opened a TAC and it looks as though we will be swapping fan modules, once again in hopes to remedy this issue.
We do have the newer fan modules as they are grey as opposed to the Cisco green (or whatever that color is) and upon closer inspection the part number tag reflects the new fan module assembly number.
This is happening on at least 4 of our 7606-S routers in our lab. We are just about to install these 7606-S routes into our operational network and I am pretty sure they will also reflect the same incorrect information.
I've just checked on a device that has been shipped as a 7606-S and it is fine:
router#sh power | inc FAN
1 FAN-MOD-6SHS 180.18 4.29 OK
router#sh ver | inc image
System image file is "bootdisk:c7600rsp72043-advipservicesk9-mz.122-33.SRC.bin"
What sh inventory provides to you?
sh inventory | inc FAN
NAME: "FAN-MOD-6SHS 1", DESCR: "High Speed Fan Module for CISCO7606-S 1"
PID: FAN-MOD-6SHS , VID: V01, SN: DCH11494015
if this show provides the correct output you have a way to check the presence of the correct FAN type
Hope to help
If I remember right, we experieinced and issue similar to this. I believe the fix was a firmware upgrade for the router. Part of the problem we also experieced along with this was the router reporting the wrong fan speed. Hope this helps.
