Hello:
We ran into a strange issue 2 days ago on the PowerConnect M6348. The switches are installed in a M1000e chassis. It lost connectivity for one minute. It then reconnected after one minute. When the switch was "down" during that minute, we lost connectivity to the machines that are connected to it.
After the recovery, the M1000e chassis web screen shows "A failure is detected on IO module A1". I tried to access the switch via the http web gui. But that is no longer available. The only way I can get into the switch is through ssh.
I ssh to the switch and issued "show logging", I saw the followings:
NOV 18 04:23:34 172.17.0.7-2 TRAPMGR[317029568]: traputil.c(637) 892 %% Stack Port Link Up: Index: 200 Unit: 2 Tag: 0/51

NOV 18 04:22:36 172.17.0.7-2 TRAPMGR[315273680]: traputil.c(637) 887 %% Unit 2 identified a link failure in the stack. 0/51
NOV 18 04:22:36 172.17.0.7-2 TRAPMGR[317029568]: traputil.c(637) 886 %% Stack Port Link Down: Index: 200 Unit: 2 Tag: 0/51
I am trying hard to find out why the stack port link went down briefly. But I got nothing so far. Another strange thing is, when I issued command "show system", I notice the switch said one of the power supply has error. As far as I know, there is no power supply in the blade switch. I posted the "show system" & "show version" output below.
Can anyone give me some pointers as to how to identify the reason behind the "Stack Port Link Down"?
Thanks in advance.
Eric
