• Immediate replacement: When a PSU fails, it should be replaced
immediately. However, do not remove the PSU module unless a
replacement is readily available. Removing a PSU without a
replacement will cause severe disruptions to the internal airflow and the
subsystem will overheat, possibly causing irreparable damage to some
of the subsystem components.
5.5.2 Replacing the PSU Module
WARNING!
Although the PSU modules are fully redundant, it is not advisable to run
the FALCON II with a single PSU module for an extended period of
time. If the second PSU module fails, the subsystem will be shut down.
To replace a PSU, please follow these steps:
1. Turn off the PSU. Using the power switch located at the top of the rear
panel, directly above the PSU module. (See Figure 5-11)
2. Remove the power cable that connects the FALCON II to the main
power source. The power socket is found on the left side of each power
supply module. (See Figure 5-11)
