American Power Conversion SYMSTRF3I Power Module Replacement, Replacement Module Verification

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 SymmetraTM must be placed in manual bypass mode, or the load equipment must be switched “off.” To place the SymmetraTM in manual bypass, switch the maintenance bypass switch to the “on” position. When the SymmetraTM 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 SymmetraTM was placed in manual bypass in step

1above, return to normal operation by switching the maintenance bypass switch back to the “off” position.
