For some reason, ExtremeXOS doesn’t have a simple command to display the boot time or uptime for switches comprising a stack. However, one of their support techs, posted a command in their support forums that gives you the power-on date and time. To view it for all stack members, run the following command after connecting to the ExtremeXOS console on the stack’s master switch-

debug hal show platform cardInfo | i "Slot:|PowerOn"

You’ll be presented with the “PowerOnDate” for each stack member.

Note: Depending on a number of variables, you may see more than one “PowerOnDate” per slot.
