Replacing the Fuse

The primary and redundant AC power circuits are independently fused. The fuses
are accessible on the rear panel of the switcher. If a fuse opens, the associated
primary or redundant power loop will shut down. If this BME does not have
redundant power supplies, the switcher will shut down. Replace the fuse as
follows:
