5.5.3.2Verify Connection To Each Active Modem

The LEDs are arranged in columns corresponding to each modem, and should accurately reflect the status of each.

Step Procedure

1Verify that the Status LED for each modem shows a GREEN light, indicating no faults. (The LEDs [on the Switch] will reflect the LEDs on the front panel of each modem.)

2Verify that the Online LED is lit for all connected TMIs with the modems attached.

3 Verify that the Online LED is not lit for the Redundant Modem (for systems not using the CRS-280L IF Switch).

4 Verify that the Bridge LED is lit for only one Traffic Modem.

For modems: Use the INFO and MONITOR menus to view the status of the modems, in addition to viewing the LEDs.

For Switch: Use MONITOR Æ COMM-STATEto verify the modems that are responding via remote control.

For real-time monitoring: Use MONITOR Æ I/O to verify the modems that are responding via remote control. Communication is slowed to aid viewing.

5.5.3.3Set Operation Mode

The CRS-300 is shipped in the Auto-Off (i.e. Manual) operating mode. This setting causes the Stored Event LED to blink. The system is operational; however, it is still operating in Manual mode. In the menu, this manual mode is called Auto-off. While in Manual mode, the User can manually select which Traffic Modem will be bridged or backed-up.

While in Manual mode, the Switch does not automatically react to any Traffic Modem failures it detects. Comtech EF Data recommends that an unattended system be configured to operate in Auto mode.

When Auto mode is enabled, the first active modem that fails is first bridged by the Redundant Modem, and then backed up.
