disconnected last.
Statement 1046
Caution We recommend grounding the chassis, even if the rack is already grounded.
Note If the rack is less than 25-in. (635 mm) deep, the slider rails will cover the grounding hole. Therefore,
the rack must either be grounded or at least 25-in. (635 mm) deep.
Caution All power supplies must be grounded. The receptacles of the AC power cables used to provide power to
the chassis must be the grounding type, and the grounding conductors should connect to protective earth
ground at the service equipment.
