5.0 OPERATION
Once you have configured each Model 1001CC and connected the
cables, you are ready to operate the unit. Section 5.0 describes the
LED status monitors, the power-up procedure, and use of the Model
1001CC.
5.1 LED STATUS MONITORS
The Model 1001CC features five front panel LEDs that indicate the
condition of the modem and communication link. These LEDs operate
as follows:
•
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.
5.2 POWER-UP
There is no power switch on the Model 1001CC: Power is
automatically applied to the 1001CC when its card-edge connector
touches the chassis’ mid-plane socket, or when the chassis’ power is
turned on.
Note: The 1001CC is a “hot swappable” card—it will not be
damaged by plugging it in or removing it while the rack is powered up.
