Description
HP Procurve Switch GL/XL
Redundant Power Supply
Description
The HP Procurve Switch GL/XL Redundant Power Supply (HP J4839A) is a
redundant power supply that you can add to any of the HP Procurve Series
4100GL and Series 5300XL Switches to provide additional switch reliability.
Features: The HP Procurve Switch GL/XL Redundant Power Supply is iden-
tical to the power unit that is preinstalled in the HP Procurve Series 4100GL
and Series 5300XL Switches, and has the following features:
 power redundancy—if either one of the power supplies should fail, the
remaining supply provides the power to continue running a fully loaded
Series 4100GL or Series 5300XL 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 Series 4100GL and Series 5300XL Switches can immediately detect the
condition and report it via the Power Status and Fault LEDs on the switch.
Event messages will also be displayed in the switch console event log and
the web browser interface Alert log.
Included Parts. The Switch GL/XL Redundant Power Supply has the follow-
ing components shipped with it:

Installing the Power Supply
Installing the Power Supply
Overview
The installation steps are:
1. Install the power supply in the power supply slot in the back of the Series
4100GL or Series 5300XL Switch (see page 3).
2. Connect the power cord (see page 4).
3. Verify that the power supply is installed correctly (see page 5).
Installation Cautions:
 Make sure that the power source circuits are properly grounded, then use the power cord
supplied with the power supply to connect it to the power source.
If your installation requires a different power cord than the one supplied with the power supply,
be sure the cord is adequately sized for the switch’s current requirements. In addition, be sure
to use a power cord displaying the mark of the safety agency that defines the regulations for
power cords in your country. The mark is your assurance that the power cord can be used safely
with the power supply.
 When installing the switch, note that the AC outlet should be near the switch and should be
easily accessible in case the switch must be powered off.
 Ensure that the power supply does not overload the power circuits, wiring, and over-current
protection. To determine the possibility of overloading the supply circuits, add together the
ampere ratings of all devices installed on the same circuit as the switch with this power
supply and compare the total with the rating limit for the circuit. The maximum ampere
ratings are usually printed on the devices near their AC power connectors.
 Do not install the power supply into a switch that is in an environment where the operating
ambient temperature might exceed 55°C (131°F).
 Make sure the air flow around the sides and back of the switch is not restricted.
 Make sure that for any switch power supply slot into which a power supply is not installed,
the cover plate is installed to cover the slot. A cover plate is required for safe operation,
and to ensure proper switch cooling.
 The switch power supplies are hot swappable; they can be installed or removed 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.
Caution:
.Refer to the installation guide for proper power cord selection.
.Disconnect AC power from this power supply BEFORE installing or removing
the supply. Otherwise, damage to the e uipment may result.

Installing the Power Supply
Installation Steps
Follow these steps to install the power supply into the back of the switch:
1. Remove the power supply slot cover with either a flat-bladed or
Torx T-10 screwdriver. Retain the slot cover for future use.
2. Insert the power supply into the opening making sure it is centered
in the opening. This will assure that the guide rails on the bottom of the
power supply engage the rails on the bottom of the switch. Then, slide the
power supply all the way in until its bulkhead contacts the back face of
the switch.
Caution Make sure that AC power is not connected to the power supply being
installed before installing the power supply into the switch. The switch
can be receiving power from the other power supply during the instal-
lation of the second unit.
3. Tighten the four retaining screws that hold the power supply in place
until the screws are secure, as shown in the next illustration. The screws
can be tightened with either a flat-bladed or Torx T-10 screwdriver. Be
careful not to overtighten the screws.
center the power supply in the
opening and push it all the way back
until the bulkhead on the power
supply makes contact with the back
face of the switch.

Installing the Power Supply
4. Connect the power cord supplied with the power supply to the power
connector, and then into a properly grounded electrical outlet. To provide
true redundancy, the 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.
