Installing the Components
Page 106 7705 SAR-8 Installation Guide
Before you begin, verify that:
• the equipment rack is securely installed, anchored, and grounded. Refer to the rack 
manufacturer’s documentation for instructions.
• the power to the rack is OFF
Tools required:
• torque driver for Phillips screws
To install a distribution panel in the rack:
Step 1. Attach the rack-mount brackets to the panel as shown in Figure 29.
Step 2. Lift the panel and position it in the rack. Ensure that there is at least 1 RU of empty 
space above or below the 7705 SAR-8 to run cables. See Managing Cable 
Connections to Adapter Cards on page 109.
Step 3. Align the mounting holes on each bracket to the mounting holes on the rack uprights. 
Insert a screw into each mounting hole and tighten. 
Step 4. Ground the panel to the building ground using one of the methods described below.
a) If a ground stud is present on the panel, see Chassis Ground Wiring on page 85.

Warning: Some panels have a grounding tab riveted to the side of the 
chassis. Do not use the ground tab to make the building ground connection 
because it does not conform to GR-1089-CORE specifications. Using the 
grounding tab may result in equipment damage or loss of data.
