NSERTING AND REMOVING POWER MODULES
This chapter discusses the physical insertion and addition of modules to the system, the physical removal of
power modules from the system, and the related changes to the system configuration.
Note: If you remove a UPS module from the UPS while the module is operating, wait five minutes
before reinserting the module. This allows the module's capacitors time to discharge.
There are four basic operations that can be performed in this respect:
•
First-time insertion of modules at time of system installation.
•
Replacement of a module in an installed system.
•
Addition of a module to an installed system.
•
Removal of a module from an installed system.
The physical insertion and removal of modules is quite simple; informing the system of the addition or
removal of the module is slightly more complicated but not difficult, as explained below.
4.1
Physical insertion of a UPS module
1.
Verify that you are holding the module with the top side up.
2.
Insert the rear of the module into the module shelf.
3.
Gently but firmly push the module all the way in so that the connectors on the rear of the module mate
with those on the inside rear of the shelf.
4.
Hand-tighten the two screws to secure the modules in place – one on each side of the front panel.
