AXP 1410 Installation and Use (6806800H70D)

4.3 Replacing Power Entry Modules

The AXP 1410 supports two Power Entry Modules (PEMs). Since the shelf is equipped with a

redundant power distribution system, the removal of a single PEM does not interrupt system

operation. PEMs are accessible from the rear of the shelf. Each PEM has EMI gaskets on all sides

of the module that provide EMI shielding.

The following instructions describe how to replace a power entry module. For further

information on power entry modules, refer to Power Entry Module (PEM) on page 102.
