Power Connector; Redundant Power Supply - HP 5400R zl2 Series Nstallation And Getting Started Manual

Introducing the HP 5400R zl2 Switches
Back of the Switch

Power Connector

The Series 5400R zl2 Switches do not have a power switch; they are powered
on when connected to an active AC power source.
The 5400R zl2 switches automatically adjust to any voltage between 100-127
volts or 200-240 volts when using the J9828A power supply, 110-127 volts or
200-240 volts when using the J9829A power supply, and 115-127 volts and 200-
240 volts when using the J9830A power supply, and either 50 or 60 Hz. There
are no voltage range settings required.

Redundant Power Supply

Load-sharing redundant power supplies J9828A, max 630W, system power
(12V), 275W of POE power; J9829A, 630W max system (12V) power, 900W max
POE power; J9830A, 630W max, system (12V) power, 2500W max POE power
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.
N o t e
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.
C a u t i o n
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.
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.

CAUTION:
.
Refer to the installation guide for proper power cord selection
.
Disconnect AC power from the power supply BEFORE installing or
removing the supply. Otherwise, damage to the equipment may result.
