Replacing a
Power Supply
The AsantéHub 2072RPU is powered by two identical power sup-
plies. Replacing either one of the units can be done with power
on the hub. There is no need to shut down the hub and remove it
from network service. To replace a power supply, follow these
simple instructions and refer to the accompanying illustration.

Unscrew the two power supply retaining screws located
on the power supply face plate.

Grasp the handle on the front of the power supply and pull
straight out, removing the unit from the chassis.

Insert the new unit into the chassis, being careful to align
the edges of the power supply card with the card guide in
the chassis. Push straight in on the handle until the edge
connector at the rear of the power supply seats in its slot.

line automatically and begins load sharing..
