Power Module or Battery Charger Module Replacement
The Avaya RS9 hot-swap feature allows you to replace a power module
or battery charger module easily without disconnecting the load or
damaging the UPS.
NOTE
The UPS may switch to internal bypass if the remaining power modules are
insufficient to supply the required power. If empty slots exist, install replacement
modules before removing original ones.
Use care in removing and installing power modules or battery charger
modules. To remove a power module:
1.
Remove the front cover panel.
The panels have spring latches on the left and right sides that
hold them in place.
2.
Loosen the thumbscrew on the module handle. Press down on
the latch release at the center of the module handle and pull the
handle down.
As the module handle fully extends, the module disconnects.
Slide the module slowly out of the cabinet.
3.
Use two hands to support the module. When fully extended,
lower the front down slightly and lift the rear edge over the
safety stop on the center support rail.
4.
Treat the original and replacement modules with care to avoid
damaging connectors or internal circuitry. Label the original
module with masking tape or some other identifier. Update the
customer record to reflect the replacement parts.
