Installing Power Shelf Grounding Brackets; Prerequisites; Required Tools And Equipment; Steps - Cisco SRS Series Installation Manual

Installing and Removing Power Components
Step 5
When the shelf is partially out of the chassis and the ejector handles are away from the pins, hand-tighten the handle
screws back into the shelf.
Step 6 Slide out the shelf out so that two people can safely remove it and carefully set it down on a flat surface.
Caution Because of the weight of the power shelf and the rack-mounted height of the chassis, you should be especially
careful while lifting and removing the power shelf. To prevent injury, keep your back straight and lift with your
legs, not your back. Avoid sudden twists or lateral moves. It is safer to use two people and a ladder to install
or remove the power shelf rather than a single person. After two people have placed the power shelf in position,
one person can slide it into place.
What to do next
After performing this task, replace the upper grille on the front (PLIM) and rear (MSC) sides of the chassis.

Installing Power Shelf Grounding Brackets

This section describes how to install the external grounding brackets on the LCC modular configuration power
shelf. The installation procedure for installing the power shelf grounding brackets is the same for both the
AC and DC modular configuration power shelves.
Caution Verify that the chassis is connected to a reliable earth ground; the chassis ground cable must be installed in
accordance with local electrical safety standards. For more information, see

Prerequisites

Before performing this task, ensure that the chassis grounding cable and both power shelves are installed in
the chassis. See
Shelf.

Required Tools and Equipment

You need the following tools to perform this task:
• ESD-preventive wrist strap
• 3/8-in. ratchet wrench with 10-mm socket
• Torque wrench with 10-mm socket and rated accuracy at 20 in.-lb (2.26 N-m)

Steps

To install the power shelf grounding brackets, go to the rear (MSC) of the chassis and perform the following
steps:
SUMMARY STEPS
1. Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection
sockets on the front (PLIM) side of the chassis or a bare metal surface on the chassis.
2. Align the shelf grounding bracket with the power shelves.
