ProCurve Switch zl Internal
Power Supplies
Description
The ProCurve Switch zl Internal Power Supply (J8712A or J8713A) is a
redundant power supply that you can add to any of the ProCurve Series 5400zl
Switches to provide additional switch reliability.
Features:
power redundancy—if either one of the power supplies should fail, the
remaining supply provides the power to continue running a fully loaded
Series 5400zl Switch.
power load sharing—with two supplies installed, each shares the power
load, which increases the life of both of the power supplies.
"hot swap" operation—you can add or replace one of the Power
Supplies without having to shut down or reboot the switch.
automatic fault detection—if the power supply encounters a problem,
the Series 5400zl Switches can immediately detect the condition and
report it by way of the Power Status and Fault LEDs on the switch and
the Fault LED on the power supply. Event messages will also be displayed
in the switch console event log and the web browser interface Alert log.
Power and Fault LEDs—The Power LED (green) is lit when power is
supplied to the power supply. The Fault LED (orange) is lit when there is
a fault condition with the power supply.
The two power supplies are different in there input and output power
specifications. Any combination of the J8712A and J8713A Power Supplies can
be used. However, be sure to verify the specific power requirements necessary
for your network.
