Replacing the Power Supply
If a second power supply has been installed, you can replace either of
the two power supplies without taking the system offline (that is, you
can “hot swap” one of two installed power supplies).
Caution Be careful not to open the router door more than 90°. Opening the door
further could damage it.
Note If a second power supply has been installed and one of them has been
found to be faulty (that is, the Pwr LED is lit), the faulty power supply is
the one for which the switch LED is not lit.
1. Disconnect the power cord from the faulty power supply, and save it
for reconnection after the new module is installed.
2. Open the front door of the router by pulling its lock—the round post
at the upper right—to the right.
3. Using a Torx T-10 screwdriver, remove the screw(s) from the top cor-
ner(s) of the power supply. (See figure 3-15.) A power supply in-
stalled in the left compartment has screws in both corners; a power
supply installed in the right compartment has a screw only in the up-
per-left corner.
