Grounding the Chassis

System Ground Location on the Cisco MDS 9509 Chassis
Caution
Grounding the chassis is required for Cisco MDS 9506 Directors that have DC power supplies, and Cisco
recommends grounding for all other chassis types, although the rack is already grounded. A grounding
pad with two threaded M4 holes is provided on the chassis for attaching a grounding lug. The ground
lug must be NRTL listed. In addition, copper conductor (wires) must be used and the copper conductor
must comply with the NEC code for ampacity.
