Instructions for Installing the Power Supply Unit (P/N 1175006L2)
Follow the steps below to install the Power Supply Unit.
1. The Power Supply Unit inserts directly into the common card area in the position labeled PSU.
The unit is mechanically keyed to prevent insertion in any other slot.
2. To install the PSU, grasp the unit by the faceplate while supporting the bottom side.
Access modules are intended to be serviced by qualified service personnel only.
Electronic modules can be damaged by static electrical discharge. Before handling
modules, put on an antistatic discharge wrist strap to prevent damage to electronic
components. Place modules in antistatic packing material when transporting or storing.
When working on modules, always place them on an approved antistatic mat that is
electrically grounded.
Prior to circuit card installation, remove the chassis card-lock safety bar by disengaging
the captured screw and lifting the safety bar away from the chassis.
