Chassis grounding instructions

Procedure 7 describes how to ground the Option 11C Mini Main Chassis and Chassis Expander. Repeat the steps for each Main Chassis and Chassis Expander installed in the system.

Procedure 7

Grounding the Option 11C Mini chassis

1Make sure that you disconnect the AC power cord from the power outlet.

Note: For rack/cabinet configurations, equipment must be powered from the same service panel.

WARNING

Never connect power to a chassis that is not grounded correctly.

2Install an NTBK80 grounding block near the chassis. See Figure 37.

Note: Use the grounding block as a bridging point for ground wires from up to six nearby Option 11C Mini Main Chassis and Chassis Expander pairs. If you have additional chassis, you require additional grounding blocks.
