Procedure 7
Grounding the Option 11C Mini chassis
1 Make 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.
2 Install 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.
WARNING
Never connect power to a chassis that is not grounded correctly.
