Introducing the HP 5400R zl2
Switches
can be installed in the back of the 5400R zl2 switches. To provide redundancy,
each power supply should be connected to different AC power sources. Then,
if one AC power source fails, the switch will continue to run.
Note Any combination of J9828A, J9829A and J9830A power supplies can be used
in the same switch. However, HP recommends to only use like supplies in a
unit for more deterministic behavior in event of a power supply failure.
Caution The switch redundant power supply is hot swappable, but, as indicated by the
caution statement on the power supply, it must be disconnected from AC
power before being installed or removed.
CAUTION:
.
.
Disconnect AC power from the power supply BEFORE installing or
removing the supply. Otherwise, damage to the equipment may result.
.
Refer to the installation guide for proper power cord selection
Because the switch can run on a single supply, removing a redundant supply
will not interrupt switch operation. However, with a single power supply
system will power on Interface module up to 630W. The rest of the Interface
modules are powered on the priority of the slot. The slot A has the highest
priority and the slot L has the lowest priority.
When power is restored from a second (or more) power supplies, a system
reload or interface module reset is not required to restore operation to slots
G-L. The 5400R modules will restart by themselves when power recovers.
To reset the interface modules, pull each module out about half way and then
re-seat them. Do this for each module in slots G-L. For more information
regarding power see the:

tation Guide.
