Caution – The outlet must be a 200-240 VAC 30A circuit intended solely for use by
the server cabinet. The electrical receptacles must be grounded, and the grounding
conductors serving these receptacles must be connected to the earth ground at the
service equipment.
Caution –
Do not disconnect the AC power cord from the wall socket when you
work on or in the server cabinet. This connection provides a ground path that
prevents damage from electrostatic discharge.
Caution –
Never move the system or expansion cabinets when system power is on.
Excessive movement can cause catastrophic disk drive failure. Always power the
system OFF before moving it.
