Adding a Rectifier or DC-DC Converter Module to an Existing Shelf
To increase system current capacity, a Rectifier Module (PCU) can easily be added to an existing shelf that
contains an empty Rectifier Module mounting position. Likewise, in systems that accept DC-DC Converter
Modules, to increase subsystem capacity a DC-DC Converter Module can be added to a shelf that contains an
empty Converter Module mounting position. Follow the procedure detailed below.
Rectifier and DC-DC Converter Modules can be inserted or removed with power applied (hot swappable).
The module location diagram on the front of each shelf shows which type modules can be operated in that
shelf. (See
Figure 2 .) Rectifier Modules will operate in any mounting position in any shelf. If a shelf accepts
DC-DC Converter Modules, they must be installed in any or all of the four middle mounting positions.
Figure 2:
Module Location Diagrams (on the front of each shelf)
NOTE!
Each Rectifier and DC-DC Converter Module locks into the Module Mounting Shelf through a
latch located on the right-hand side of the module. The latch and module handle are interactive.
Pushing the handle into the module’s front panel causes the latch to extend to the locking position;
pulling the handle out from the module’s front panel causes the latch to retract. See
Figure 3
for handle
operation.
WARNING! To prevent damage to the latching mechanism, ensure the handle is in the open position
when installing or removing a module. NEVER hold the handle in the closed position when installing a
module into a shelf.
