How Do I Replace a Fuse?
- Power off the system. For details, see System Power-Off.
After the system is powered off, the remaining electricity and heat still exist in the chassis, which may cause electric shocks or burns. Therefore, you need to wear protective gloves and perform operations 5 minutes after the system is powered off.
- Loosen the screws on the fuse shell.Figure 9-1 Removing the screw shell
- Lift the fuse box opening, remove the fuse, insert a new fuse into the slot, and close the fuse box. If you hear a click sound and the bulge on the side is inside the box, the fuse box is properly installed.Figure 9-2 Replacing a fuse
