HP Switch zl2
Internal Power Supplies
Description
The HP Switch zl2 Internal Power Supplies (J9828A, J9829A or J9830A) are
redundant power supplies that you can add to any of the HP zl2 switches to
provide additional switch reliability.
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 5400R zl2 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
specifications.
The J9828A, J9829A, and J9830A power supplies can be paired within the same
switch.
The mixing of power supplies is supported, but not recommended.
