Installation Overview

This section describes the tools and equipment needed for installation, the applicable safety warnings,

and the installation guidelines:

• Tools and Equipment, page 3-1

• Installation Guidelines, page 3-1

Tools and Equipment

Obtain these necessary tools and equipment:

• Ratcheting torque screwdriver with a number-2 Phillips head that exerts up to 15 pound-force inches

(lbf-in.) or 240 ounce-force inches (ozf-in.) of pressure. For 1150-W power-supply modules, the

screwdriver shaft length should be at least 6-inches long.

• Power-supply power-cord retainer assembly in the switch accessory kit.

Installation Guidelines

Table 1-11 and Table 1-13 list the switches and the compatible power-supply modules. Observe these

guidelines when removing or installing a power supply or fan module:

• Do not force the power supply or fan module into the slot. This can damage the pins on the switch

if they are not aligned with the module.

• A power supply or fan module that is only partially connected to the switch can disrupt the system

operation.
