The router uses fuses from the Cooper Bussman brand GMT series for the CB, SIBs, and
FPCs. The fuses are located in the rear of the midplane behind the power supply in slot
PEM0 . When the fuse for a component blows, the component stops functioning even
though it is installed correctly and the power supplies are providing power to the router.
For more information, see "Troubleshooting the M320 Fuses" on page 133. For fuse
replacement instructions, see "Replacing an M320 Fuse" on page 204.
