Power off the power module to be replaced.
Do not power off the other power module during the replacement.
Do not touch the other power module either by body or by tools, preventing human
injury or device short circuit.
DC and AC power modules are incompatible with each other and cannot be used in
substitution.
NOTE
The AC power module used by the current USG6680-AC is 700 W, but the AC power module used by
the early-stage USG6680-AC is 350 W. If both the 700-W and 350-W power modules are used after the
power modules are replaced, the 700-W power module can serve as the 350-W power module only.
Press the baffle on the cable retention clip and remove the cable retention clip from the
AC power cable.
Pull out the power cable from the socket on the power module.
Use the Phillips screwdriver to loosen the screws at the upper-left corner of the power
module.
Grasp the handles of the power module and gently pull toward you to guide the power
module out of the slot.
