Power Supplies
Description
The HP ProCurve Switch zl Internal Power Supplies (J8712A, J8713A or
J9306A) are redundant power supplies that you can add to any of the HP
ProCurve zl switches to provide additional switch reliability. These power
supplies can also be used with the HP ProCurve Power Supply Shelf (J8714A)
to provide additional PoE or PoE+ power to any of the zl switches.
Features:
■ 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 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 three power supplies are different in their input and output power
specif
ications.
The J8712A and J8713A Power Supplies can be paired within the same switch
or wi
thin the Power Supply Shelf.
The J9306A Power Supply can only be paired with another J9306A Power
Supply wit
hin the same switch or within the Power Supply Shelf. The J9306A
Power Supply cannot be used with either the J8712A or J8713A Power
Supplies.
