5.0 OPERATION

Once you have configured each Model 1004ABRC and connected the cables, you are ready to operate the units. Section 5.0 describes the LED status monitors and the power-up procedure.

5.1 LED STATUS MONITORS

The Model 1004ABRC features front panel LEDs that indicate the condition of the modem and communication link. Figure 6 (below) shows the positions of the LEDs.

•The green “PWR” LED glows when power is applied to the modem through its mid-plane chassis connection.

•The green “TD” and “RD” LEDs show positive state data activity. The red “TD” and “RD” LEDs show negative state data activity. A solid red light indicates an idle state.

•The green “CD” LED lights when the receive carrier is detected; the red LED lights when the receive carrier is absent.

5.2POWER-UP

There is no power switch on the Model 1004ABRC: Power is auto- matically applied to the 1004ABRC when its card-edge connector touches the chassis’ mid-plane socket, or when the chassis’ power is turned on.

NOTE: The 1004ABRC is a “hot swappable” card—it will not be damaged by plugging it in or removing it while the rack is pow- ered up.
