ED-64M Director Operating Features

Out-of-Band Management
High-Availability Pairs of critical FRUs installed in the director provide redundancy in
case a FRU fails. When an active FRU fails, the backup FRU takes
over operation automatically to maintain director and Fibre Channel
link operation. (This process is called failover.)
UPM cards do not automatically fail over and provide link operation after a
failure. Fiber optic cables from the failed UPM card must be disconnected
and reconnected to ports on a functional card to continue operation.
Standard redundancy is provided through these components:
◆
Power supplies — The director contains two power supplies that
share the electrical operating load. If one power supply fails, the
other supply handles the full load. Separate receptacles at the rear
of the director provide facility input power to each supply. For
full redundancy, input power for each receptacle should come
from a different source.
