Installing the Switch 5300xl Series
Installation Procedures

3. (Optional) Install Second Power Supply

A second, load-sharing redundant power supply (ProCurve Switch gl/xl/vl
RPS, J4839A) can be installed in the back of the switch. To provide true
redundancy, this second power supply should be connected to a different AC
power source from the other supply. Then, if one AC power source fails, the
switch will continue to run. Each supply provides enough power to operate a
fully loaded switch, so even if one fails, the switch will continue to operate
normally.
Install the second power supply into power slot number 2 as shown in the
illustration on the next page.
The slot cover can be removed with either a flat-bladed or Torx T-10 screw-
driver. Retain the slot cover for future use.
C a u t i o n
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.
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
For installation details, see the instructions in the manual that comes with the
power supply.
