Dell™ Rack Installation Guide 19

Installing the Cable Tray and Cable-Management

Arm

This procedure is performed in two phases. First, install the cable tray to

the back of the system chassis. Next, install the cable-management arm

on the cable tray.

Attaching the Cable Tray to the System

NOTE: Depending on the cable tray that ships with your rail kit, you will need

to follow the procedure for mounting the tray on the back of the system chassis.

Both cable trays are illustrated in Figure 1-8.

Mounting Type I

Align the formed metal tabs along the bottom of the cable tray with

the mating slots at the back of the system chassis.

Insert the tabs into the slots and rotate the tray downward to the secure

position (see Figure 1-8).

Secure the tray to the system with the two captive thumbscrews.

Mounting Type II

Align the formed metal tabs along the sides of the cable tray with the

bent metal notches on the inner walls at the back of the system chassis.

Slide the tabs over the metal notches and press the tray downward

to the secure position (see Figure 1-8).

Secure the tray to the system with the two captive thumbscrews.

CAUTION: The cable tray cannot support the weight of the system. Do not grasp

the cable tray when lifting the system. Lift the system only by the chassis edges.

Securing the Cable-Management Arm

NOTE: The cable-management arm can be installed on either side of the cable tray.

Facing the back of the rack cabinet, push the tab on the front end of the

cable-management arm into the latch on the cable tray until the latch

clicks (see Figure 1-8).

Push the tab on the unattached end of the cable-management arm into

the latch on the end of the slide assembly until the latch clicks.
