1-4 System Overview
„
One standard power supply module with a slot available for an additional redundant
power supply module. When an additional power supply module is installed, both
the standard and additional redundant power supply module slots become hot
swappable.
„
Hardware monitors (temperature, fans, and voltage) and software monitors to
indicate failures.
„
Mechanical: Keylock at the front of the chassis and two metal padlocks loops (one at
the back of each side panel). Three intrusion sensor switches for the front, left and
right side of the chassis. Two of the three intrusion sensor switches (left and right
side intrusion sensor switches only) become power inter-lock switches when two
power supplies are installed. (Tower models only.)
