Switches
3. (Optional) Install Second Power Supply
A second, load-sharing redundant power supply (either a 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 switch.
The 875 W Power Supply (J8712A) can supply up to 273 watts for PoE power.
The 1500 W Power Supply (J8713A) can supply up to 900 watts at 220 volts for
PoE power.
To prevent overloading of the building circuits breakers, the second power
supply must be connected to a different AC power source from the other
supply. This also helps with redundancy, if one AC power source fails, the
switch will continue to run.
Install the second power supply into power slot number 2 as shown in Figure
2-3.
The slot cover can be removed with either a flat-bladed or Torx T-10 screw-
driver. Retain the slot cover for future use.
Caution The switch power supplies are hot swappable; they can be installed while the
switch is receiving power from the supply in the other slot. But, as indicated
by the caution statement on the power supply, the supply must not be
connected to AC power before being installed or removed.
For safety and proper switch cooling, if either of the power supply slots are
not being used, make sure to attach the cover plate over the slot. Please see
the “Installation Precautions” on page 2-5 for more information.
For installation details, see the instructions in the manual that comes with the
power supply.
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
