Over the last couple of months we have experienced about 5 Ethernet card failures, with another three happening late last year. The problem results in all Cisco IP phones on the card losing power (the phones are powered over Ethernet) and the PCs attached to the phones becoming disconnected from the network. More worryingly the most recent occurrence resulted in two components (capacitors??) on the card burning out when we tried reseating the card in the chassis.
In all but one of the occasions we have had to replace the cards as neither a hw-module reset or a physical reseating do not clear the problem
The only indication we get that there is a problem is when you examine the Show Logs:
%PM_SCP-SP-2-LCP_FW_ERR_INFORM: Module 3 is experiencing the following error: Inline Power Module - PS volatage bad
All our User Access Switches are Cisco WS-6509-E chassis, with 2 Supervisor Engine 32 cards. All of the installed Ethernet modules used are 48-port 10/100/1000 RJ45 EtherModule "WS-X6148A-GE-45AF". And we are currently running 12.2(18)SXF4 IOS (s3223-ipbasek9-mz.122-18.SXF4)
The fault has proven to be very random, on every occasion the fault has occurred in different module slots on different chassis located in different parts of the building.
I would be interested if anyone could comment on our problem as we are struggling to ascertain what the root cause is and we are becoming more and more concerned due to the frequency that this problem is happening.
Thanks for the pointers. Did you also remember such problem causes NIC cards that are connected to the line card to be damaged? Our customer has 3 X31 IBM notebook damaged (the NIC cards) when connected to the line card. They mentioned that they observed smoke coming out of the NIC card.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
