Maintaining and upgrading the EPC-6315

Occasionally you will want to perform maintenance or upgrades on the EPC-6315.
When this occurs, you must remove the board from the carrier card, repair or install
the desired option, then re-install the board on the carrier card. The following
section describes how.

Disconnecting the EPC-6315 PMC from the carrier card

To separate the EPC-6315 from the carrier card:

1. Remove screws on the back of the carrier card.

2. Pull the boards apart while keeping them parallel. Continue applying force until

the connectors completely disengage.

After performing maintenance and/or upgrades, replace the EPC-6315 as described
in

Installing the EPC-6315 PMC on the carrier card
