CAUTION: Power down the E2 before plug- ging the modem into the PC-104 slot. Failure to do so can damage the modem and void the

warranty.

The E2’s internal modem mounts in the PC-104 slot located at the top left of the E2 main board (See Figure 2- 5). Disconnect power to the unit, and carefully plug the male pins on the back of the modem card into the E2’s PC- 104 slot. Use the standoffs and screws supplied with the modem card to secure the card to the main board, as shown in Figure 2-5. When finished, restore power to the

E2.
