2.3.3.5 AC Power
The AC power is supplied to the switch by two standard detachable, non-locking,
3-prong power cords. Normal input voltage is 90 to 264 VAC, 47 to 63 Hz. The power
supplies are self-adjusting. For maximum redundancy protection, the switch will operate
with only one power supply. Maximum power consumption is less than 10W.
2.3.3.6 Ground
A#10-32 stud is available on the rear for the purpose of connecting a common chassis
ground between all of the equipment.
