10.7 Changing a Fuse on the FC-FI
The FC-FI has seven user changeable fuses. See Table
13 for more information.
To change fuses, complete these steps:
1 Identify the blown fuse on the board visually or by
checking for continuity with a multimeter. Ensure
that the fuse is one of the user replaceable fuses
listed in Table 13.
2 Insert a screwdriver under the centre of the fuse and
pull it out.
3 Check that the replacement fuse is of the correct
current rating.
4 Put the replacement fuse on top of the connector,
taking care that the current number is facing
upwards, and press it down firmly.
11 Install Optional Cards and
Modules
At this stage connect any optional cards and modules
into the system. These might include, for example:
Slot cards such as a PLX800 loop expansion card.
The MOXA or CCU3 modules.
Printers.
Repeaters.
For a general impression of what is involved in mount-
ing slot cards, see Fig. 22.
