Replacing the Fuse

If the hub’s LEDs are no longer lit, the unit may be disconnected from its AC power cord. If the power cord is securely connected but the LEDs are still not lit, the fuse probably needs to be replaced.

The fuse is located in the hub’s AC receptacle assembly and supplied as standard equipment for the hub. It is a “quick-acting,” FSF034.1523 fuse or equivalent, rated at 5 amps, 250 volts.

To replace the fuse, follow these steps:

1.Locate the AC receptacle on the hub’s back panel.

2.Disconnect the AC power cord.

3.Carefully pry open and pull out the fuse-holder, as shown in Figure 1.
