Series 8200zl Switch
Redundant Power Supply
Load-sharing redundant power supplies (ProCurve Switch zl 875 W Power
Supply, J8712A or a ProCurve Switch zl 1500 W Power Supply J8713A) can be
installed in the back of the Series 8200zl Switch. 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.
Caution 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, on the 8212zl one power supply
will only supply enough power to run the module slots A-F. Slots G-L will not
receive any power unless there are at least two power supplies installed.
When power is restored to a second (or more) power supplies, a system reload
or interface module reset may be required to restore operation to slots G-L.
For more information regarding power see the:
■ ProCurve Switch zl Internal Power Supply Installation Guide.
■ ProCurve PoE (Power over Ethernet) Devices Planning and
Implementation Guide.
CAUTION:
.
.
Disconnect AC power from the power supply BEFORE installing or
removing the supply. Otherwise, damage to the equipment may result.
.
Refer to the installation guide for proper power cord selection
