5.2 Replacing 5-A Fuse F2
Fuse F2 (see Figure 5–2) provides power from the 3.3-V switching regulator
to the 3.3-V power plane and blows if V
CC
is shorted to GND. Shorting can
occur if a connector pin is bent during insertion or if measurements are taken
directly from the backplane.
F2 can be replaced easily with one of the spare fuses. Simply disconnect
power from the board, and pull out the fuse with pliers (see Figure 5–2). Push
in the new fuse, and reconnect the power supply.
