Replacing the Fue
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 shuts down. If this BME does not have
redundant power supplies, the switcher shuts down. Replace the fuse as follows:
1. On the rear panel, insert the flat blade end of an Extron Tweeker or small
screwdriver under the tab on the bottom of the fuse holder and gently pry on
the fuse holder until it protrudes from the rear panel (figure 6-6).

2. Pull the fuse holder clear of the rear panel.
3. Remove the fuse from the fuse holder.
4. If test equipment is available, you can check the fuse.
5. Place a new 5A/250V time delay fuse in the fuse holder.
6. Slide the fuse holder into the rear panel until it is flush with the panel.
