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.
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 (J4875A) 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.
CAUTION: Carefully follow the mechanical guides on each side of the power supply slot and make sure the
power supply is properly inserted in the guides. Never insert the power supply upside down.
4. Continue to slide the power supply towards the back of the chassis until the two metal rods and the connector
make contact with the back connector. Then push the power supply until the front panel of the power supply
is flush with the rest of the chassis.
5. Use a screwdriver to tighten the two screws on either side of the power supply.
6. Connect the power cord to the front of the power supply.
