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.
Warning – 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.
2. Turn on power to any expansion cabinets.
Read the documentation supplied with each type of expansion cabinet for
specific instructions.
