ProCurve Switch zl Internal
Power Supplies


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 zl
switches to provide additional switch reliability. These power supplies can
also be added to the ProCurve Power Supply Shelf (J8714A) to provide
additional PoE power to any of the zl switches.
power redundancy—if any one of the power supplies should fail, the
remaining supply or supplies provide the power to continue running a fully
loaded Series 5400zl or 8200zl 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 Switch 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.
