REPLACEMENT PROCEDURES
Rectifier Replacement
Danger: Observe the instructions on top of the Rectifier as you remove it.
Note: If a Rectifier is removed without being replaced, perform the UPDATE
INVENTORY procedure found in this chapter to clear alarms.
The Rectifier weighs approximately 40 lbs.
Rectifiers can be inserted or removed with power applied (hot swappable).
Procedure
1) Observe the admonishments presented at the beginning of this chapter, and
those encountered in this procedure.
2) 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 future alarms associated with
this system.
3) On the Rectifier to be removed, place the Standby/Operate switch to the
"standby" position.
Note: In the next step, a safety latch is present on the left-hand (as viewed from the
front) side panel of each Rectifier. The latch is designed to prevent the
Rectifier from inadvertently being removed completely from the Bay once it
has been installed. It should not be necessary to depress the safety latch
release when installing the Rectifier.
4) Loosen the captive fasteners on the front of the Rectifier to be removed. Use the
handle provided on the front of the Rectifier, and pull the Rectifier out until it is
stopped by a safety latch located on the left-hand side panel of the Rectifier.
Refer to Figure 6-1 for latch and release location. Depress and hold the latch
release, and remove the Rectifier from the shelf. Support the bottom of the
Rectifier as you pull it out. Observe the instructions on top of the Rectifier as
you remove it.
5) Ensure that the Standby/Operate switch on the replacement Rectifier is in the
"standby" position.
6) Slide the replacement Rectifier evenly into its mounting position. It should not be
necessary to depress the safety latch release. Secure the Rectifier to the bay by
tightening the captive fasteners located on the Rectifier.
7) Place the Standby/Operate switch on this Rectifier to the I "operate" position.
8) Enable the external alarms, or notify appropriate personnel that this procedure is
finished.
9) Ensure that there are no local or remote alarms active on the system.
