Finding EPS Power Supply Status on Brocade ICX Switches

It took me a while to figure this out, so here it is:

To find out how your chassis is doing on your Brocade ICX type the show chassis command.

The stack unit 1 chassis info:

Power supply 1 (NA - AC - Regular) present, status ok
Power supply 2 (NA - AC - Regular) present, status ok

Fan ok, speed (auto): [[1]]<->2

Fan speed switching temperature thresholds:
        1 -> 2 @ 69 deg-C
        1 <- 2 @ 64 deg-C

Sensor B Temperature Readings:
        Current temperature : 29.5 deg-C
Sensor A Temperature Readings:
        Current temperature : 38.0 deg-C
        Warning level.......: 66.0 deg-C
        Shutdown level......: 76.0 deg-C
Boot Prom MAC : cc4e.24xx.xxxx
Management MAC: cc4e.24xx.xxxx

If you only care about the power supply status type:
sh chassis | incl Power

Power supply 1 (NA - AC - Regular) present, status ok
Power supply 2 (NA - AC - Regular) present, status ok
Power supply 1 (NA - AC - Regular) present, status ok
Power supply 2 (NA - AC - Regular) present, status ok
Power supply 1 (NA - AC - Regular) present, status ok
Power supply 2 (NA - AC - Regular) present, status ok

This is the output for my switches which are 3 ICX 6450s stacked. 6450s only have a single built-in power supply, so "Power supply 2" in each case is the EPS. In my setup I have one EPS powering two switches and another one powering the last switch. There's no way to know what "Power supply 2" is with a command, as far as I know.
