5.0 OPERATION

Once you have configured each Model 1000RC 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 1000RC features thirteen front panel LEDs that indicate the condition of the modem and communication link. Figure 9 shows the positions of the LEDs and the bullets describe their functions.

†Connection to ground is optional

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

•The “TD” and “RD” indicators blink red and green to show data activity. A solid red light indicates an idle state. Solid green is an “illegal” condition and typically indicates a problem in the system.

•If your carrier detect strap is configured as “Always On”, the “CD” light will always be green. If the carrier detect strap is set to “Normal”, the green 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 1000RC: Power is automatically applied to the 1000RC when its card-edge connector touches the chassis’ mid-plane socket, or when the chassis’ power is turned on. Note: The 1000RC is a “hot swappable” card—it will not be damaged by plugging it in or removing it while the rack is powered up.
