EX4200 virtual chassis and PoE

Post #1 of 4 (677 views)

Dear Colleagues,

Do I need to know anything special to configure PoE in a virtual chassis
environment? For some reason PoE devices on ports ge-1/0/2 and ge-1/0/3 do
not get power while the same device in port ge-0/0/2 does. All details
below.

I've just tried another pair of identical EX4200s in a virtual-chassis,
and PoE on the second FPC works fine. Seems like a hardware problem on
the second chassis of the first pair.

Hello Victor,

I don't know if it's the case, but POE does not work on EX4200 with DC power supplies.
Need to use AC power supplies instead.

Regards.

All my EX4200s are identical with two AC power supplies.

Anyway, an EX4200 with DC power supplies would not probably display the
kind of "show poe interface" I had posted.
