Use the
◄ ► arrow keys to select
Manual or Auto . Press ENTER . The underline cursor’s position
indicates the current selected operating mode.
When you select Manual , the switch does not respond automatically to any modem faults, and
executes the manual setting configured via the MANUAL selection.
Comtech EF Data recommends that you configure an unattended CRS-500 1:N
Redundancy System to operate in Auto Mode. When you enable Auto Mode, the
first active traffic Modem that fails is first bridged, then backed up by a fault-free
Redundant Modem.

Config Active Modems:

A modem must be “Active” in order for it to be available to bridge or back up. Once you “activate”
a modem, the switch will expect the modem to be attached, and will poll the modem for status
information.
To select which Traffic Modems to activate, first use the
◄ ► arrow keys to select the modem,
and then use the
▲▼ arrow keys to activate or deactivate that modem.
A hyphen (–) appears in place of the modem number if that modem is deactivated or is not
plugged into that slot. If a Traffic Modem interface is not plugged into a slot, that position cannot
be activated.
