Appendix A
Fuse Replacement
This appendix contains service information that explains how to replace
the fuse in the NSG.
If your NSG has an AC power supply, the NSG uses a 5A fuse that is
located inside the power socket. A spare fuse is located inside the
compartment adjacent to the power socket.
Warning: Always replace the fuse with a fuse of the same rating and
type. Using a different fuse voids the Harmonic warranty and could
result in fire or other electrical damage.
To replace the fuse, follow these instructions:
Warning: You must disconnect the power cord before removing the
fuse.
1. Unplug the power cord from the chassis to disconnect the power.
2. Pull down the fuse cover on the back panel.
3. Remove the old fuse.
4. Install the new fuse.
5. Replace the fuse cover.
6. Plug in the NSG and turn it on.
