Rectifier Fan Replacement
Each rectifier uses a fan (P/N 32010096 for R48-2000 and R48-2000H. P/N 32010106 for R48-2000e) for
cooling. If fan replacement should become necessary, perform the following procedure.
Refer to Figure 12 as this procedure is performed.
WARNING! In a system with NO redundant rectifier, battery must have sufficient reserve to power the
load(s) while the rectifier is removed for fan replacement.
NOTE!
When performing any step in this procedure that requires removal of existing hardware, retain all
hardware for use in subsequent steps.
Procedure
1. Performing this procedure may activate external alarms. Do one of the following. If possible, disable
these alarms. If these alarms cannot be easily disabled, notify the appropriate personnel to disregard
any alarms associated with this system while this procedure is performed.
2. Remove the rectifier from the shelf. Refer to a previous procedure for step-by-step instructions.
3. Place the rectifier on a static-safe work surface. Connect an approved grounding strap to your wrist for
the remainder of this procedure.
4. On this rectifier; remove the front panel by removing the screws securing the front panel to the chassis,
and by unplugging the fan from the printed circuit card.
5. For proper orientation of the new fan, observe the location of the fan wires and the air flow arrows on the
old fan.
6. Remove the old fan from the front panel by removing the two screws and clips securing the fan.
7. Install the new fan onto the front panel using the two screws and clips previously removed. Ensure the
fan wires and air flow arrows match the orientation of the old fan.
8. Install the front panel with the new fan onto the chassis by plugging the fan cable into the printed circuit
card, and securing the front panel with the screws previously removed.
9. Replace the rectifier into the shelf. Refer to the previous procedure for step-by-step instructions.
10. When the fans start, check to ensure that each is providing front-to-back airflow. If air direction is
wrong, immediately remove the rectifier from the shelf. Repeat previous steps to check fan orientation,
and correct as necessary. Reinstall the rectifier and again check for proper airflow.
11. Enable the external alarms, or notify appropriate personnel that this procedure is finished.
12. Ensure that there are no local or remote alarms active on the system.
