MITSUBISHI ELECTRIC MS540 - Manual (Page 28)

SYSTEM EXPANSION
3/7
3. At the rear of the system unit are metal blanking plates, one for
each expansion card slot. Opposite the blanking plates, at the
front of the system unit, there are card guides. These ensure that
the front edge of a full-length card is supported securely.
4. First decide in which of the available slots you wish to install the
card. In general it is easiest to start with the lowest slot and work
upwards.
5. Check on two things, the type of board (ISA or PCI) and then its
length. Not all slots take the same length or type of card.
6. Remove the blanking plate of the chosen slot by removing its
securing screw. On the power supply side, remove the security
plate, then slide the blanking plate out of its slot. Keep all the
screws, etc., they will be needed later to secure the card.
7. If the card you are installing is configured by the means of
jumpers or switches, check that it is correctly configured before
proceeding.
Note
If the card uses the video or audio feature connector on the motherboard, you
may need to connect this before you install the card (otherwise, the card could
get in the way of the connector). See appendix B,’System Motherboard’ for
location of these connections.
