I currently have four ex4200 switches run in their own virtual chassis with 11.4R2.14 firmware.
Today all clients connected to member 03 LC in the chassis lost connection to the network. When i looked at the switch in the server room the LCD screen reported no alarms and it looked fine, except there were no lights on the ports that the clients connect to.
To fix this i had to reboot the switch but i'd like to know if anyone has ever come across this issue? There is nothing in the show log messages to indicate what happened. Is there any other logs i could look at to try and find out what happened?

Unfortunately there isn't any support on this switch to log a call. I'm going to swap it out tonight.
After more digging i found the following error in the log "/kernel: Buffer management parity error detected in mpfe1, value 0, re-init the PFE".
