Power Module Replacement
1. Remove the appropriate grill cover. The power module bays are labeled on the center spine of the frame,
behind the grill covers.
Note: If replacing a non-redundant power module, or if the failed power module is the only power module, the
Symmetra
TM
must be placed in manual bypass mode, or the load equipment must be switched “off.” To place the
Symmetra
TM
in manual bypass, switch the maintenance bypass switch to the “on” position. When the Symmetra
TM
is
in bypass mode, the load equipment is unprotected from power failure.
2. Use a flathead screwdriver to release the flip latch from the power module.
3. Note the two drop lock seating tabs at the front of the power module. These drop locks hold the module firmly
in the Power Array frame. When removing a failed power module, lift the front of the module slightly to release
the drop lock seating tabs, and then pull the module from the bay.
4. Remove the power module from the frame.
5. Return the power module to the appropriate service provider, or return it directly to APC for recycling.
6. Install the replacement module and tighten the flip latch. If Symmetra
TM
was placed in manual bypass in step
1 above, return to normal operation by switching the maintenance bypass switch back to the “off” position.
