Select which Traffic Modems to activate. Use the ◄ ► arrow keys to select the modem, then use
the ▲ ▼ arrow keys to activate or deactivate the modem.
An hyphen (-) appears in place of the modem number if it is deactivated. If a Traffic Modem
interface is not plugged into a slot, that position cannot be activated. A modem must be active in
order for it to be available to bridge or backup. Once activated, the Switch will expect a modem
to be attached, and will poll the modem for status information.
When adding or removing a modem in an operating 1:N Switch system, it is important to keep the
traffic safe, by preventing any contention in the system from an unsuppressed modem Tx carrier.
To add an additional Traffic Modem:
• Attach control, data and IF cables as outlined in
Chapter 4. CABLES AND CONNECTIONS.
• Configure the modem and Switch as outlined in
Chapter 5. MODEM, RMI/TMI, AND
SWITCH CONFIGURATION.
To remove a Traffic Modem that is not being backed-up:
•
De-activate the modem from the Switch configuration (CONFIG: ACTIVE, ▼ arrow for
the appropriate TMI/modem position).
•
Power-down the modem.
•
Detach all cables.
To replace a faulted Traffic Modem that is being backed-up by the Redundant:
•
Detach the IF cables of the faulted modem.
•
Power-down the modem.
•
Remove all other the cables and remove the modem.
•
Install the replacement modem.
•
Attach the power cord and power up the modem.
•
Attach control, data and IF cables as outlined in Chapter 4. CABLES AND
CONNECTIONS.
•
Configure the modem as outlined in Chapter 5. MODEM, RMI/TMI AND SWITCH
CONFIGURATION.
•
The new Traffic Modem should lock as it is bridging the Redundant Modem. The Switch
will then ready and able to cope with any other fault that may occur.
CAUTION
Do not deactivate this modem, as the traffic path must be maintained.
