Padlock Loops: The two side cover padlock loops enable you to
insert padlocks (not provided) to secure the side covers to the
system unit.
The electro-magnetic interference (EMI) door on the front of the
server also has a padlock loop. You can insert a small padlock
(not included) through this loop to secure the EMI door to the
system unit and help prevent unauthorized access to the hard
disk drives in the hot-swap bays.
Power Supplies: All PC Server 704 models support three
420-watt power supplies. In a three-supply system, the third
power supply provides redundant power.
