2.4 Installing Option Cards
Each option card is shipped with installation
instructions specific to that card. The general
procedure for all option cards is as follows:
Option cards are not hot-pluggable.
Disconnect power to the 920i before
installing option cards.
1. Disconnect power to the indicator. Remove
backplate as described in Section 2.2 on
page 10.
2. Carefully align the large option card connector
with connector J5 or J6 on the CPU board (see
Figure 2-9). Press down to seat the option card
in the CPU board connector.
3. Use the screws provided in the option kit to
secure the other end of the option card to the
threaded standoffs on the CPU board (see
Figure 2-9).
4. Make connections to the option card as required.
Use cable ties to secure loose cables inside the
enclosure as shown in Figure 2-10. When
installation is complete, reassemble the
enclosure as described in Section 2.6 on
page 17.
