HP Procurve Routing

Installing (or Removing) Redundant Power Supplies

Determining Power Supply Status

If you are replacing a power supply that has failed and you are not sure which supply has failed, enter the following

command at any CLI command prompt:

show chassis

This command displays status information for the fans and the power supplies. The power supplies are numbered

in the display. The power supply numbers correspond to the following positions. These positions assume you are

facing the front of the chassis, not the rear.

NOTE: The 9315M requires a minimum of two J4875A power supplies to power-up or reboot. With only two

power supplies installed, if it becomes necessary to replace a failed power supply, you must first install and power-up the replacement power supply before you remove the failed power supply. Otherwise, the 9315M routing switch

will cease to operate. Also, for true power supply redundancy(N+1) in both the 9315M and the 9308M, you must

install all four power supplies in these units.

Installing Power Supplies

To install a power supply in the chassis, do the following:

CAUTION:Install the J4147A Power Supply only in the HP 9308M (J4138A) and HP 9304M (J4139A)

Routing Switch chassis. Install the J4875A Power Supply only in the HP 9315M (J4874A) Routing Switch.

The J4147A and J4875A Power Supplies are not interchangeable.

CAUTION:Power supplies are hot swappable but they should be disconnected from AC power before being

installed or removed. That is, the Routing Switch can be running while a power supply is being installed or

removed, but the power supply itself should not be connected to a power source. Otherwise, damage to the

power supply or the Routing Switch could result.

1. Use a screwdriver to remove the blank power supply face plate. This will expose the empty power supply slot.

2. Remove the power supply from its packaging; or, if the power supply is connected to a power source, remove

the power cable.

3. Holding the bar on the front panel of the power supply, insert the power supply into the empty power supply

slot using the module guides provided on either side of the compartment.
