BlackDiamond 8800 Series Switches Hardware Installation Guide

Remove the helper bracket from the system rack after the chassis is secured. Save the bracket for 
future use if you remove the chassis from the rack.

Although grounding the BlackDiamond 8800 series chassis is optional, it is recommended. A grounding 
point with integrated pem-nuts is provided on the back of the chassis.

You need the following materials to ground the chassis:

●

Two 10-24 screws

●

One copper, standard barrel 2-hole compression grounding lug, type LDC, equivalent to Panduit 
part number LCD4-14A-L or Thomas & Betts part number: LCN4-14

●

Appropriate grounding wire for your system, based on the available input current for the power 
supply:

■

For AC systems using a 20A breaker per PSU (SSI AC), the chassis ground can be as small as 
14 AWG. 

■

For DC systems using a 40A breaker per PSU (SSI DC), the chassis ground can be as small as 
10 AWG.
