Maybe, maybe not.

NAV will populate the list of power supplies and fans from
ENTITY-MIB::entPhysicalTable. If this table is not supported, or not
fully populated by Brocade's implementation, NAV will not find any PSUs
and fans.

If Brocade does, you may get a list of these entities - but, you won't
get their status. NAV currently only supports proprietary MIBs from
Cisco and HP to get the actual status of the collected fans and PSUs.

If you know which MIBs can provide this information for Brocade devices,
that's the first step to actually implementing support for it.
