7.2.4 Power Socket Fuse Replacement
Under normal operating conditions you would not need to replace the power socket fuse, however, in the event
of a severe power surge occurring in a power circuit providing AC electrical power to the OptiStar EdgeSwitch,
it is possible that the fuse may burn out. To change the fuse, locate the compartment at the bottom of the power
cord socket on the back of the switch. With a screwdriver, pry out the fuse tray and remove the fuse.
