CLO-10 Link Optimizer Revision 1
Redundant System Operation MN/CLO-10.IOM
A.6.3.4 Establish the Operating Mode
When adding or removing a CLO-10 in an operating 1:N system, it is important to keep the
Traffic safe by preventing any contention in the system from an unsuppressed modem Tx carrier.
Operating Mode determines if the Redundancy Unit will automatically switch if it detects faults on
any active Traffic Units: this is AUTO-ON, or automatic operating mode. If AUTO-OFF mode is
selected, then the Redundancy Unit is in manual operating mode and it will not backup any traffic
unit on its own. The user may select which Traffic Unit he wants bridged or backed up.
A.6.3.4.1 Switch Auto Off/On
If Auto(OFF/ON) is selected:
OPERATING MODE:
AUTO-OFF AUTO-ON
AUTO-OFF is the manual operating mode, while AUTO-ON is the automatic operation mode.
Select AUTO-OFF or AUTO-ON using the ◄ ► arrow keys, then press ENTER.
When in the AUTO-OFF (manual operating) mode, the CLO-10 does not respond automatically
to any unit faults and simply performs the bridge or backup settings selected by the user from the
Manual menu (see next subsection).
When in AUTO-ON (automatic operating) mode, the system has control of backup and will
automatically backup any active Traffic Unit based on its fault status.
A.6.3.4.2 Redundancy Unit – Manual Select
If Manual is selected, one of two screens may be shown.
When in AUTO-OFF (manual switching) mode, the Manual Select display would appear as
shown below:
MANUAL SELECT:
BRIDGE:02 BACKUP:02
When in AUTO-OFF (manual operating) mode, both of these selections are available. Use the
◄ ► arrow keys to select between BRIDGE and BACKUP then, using the ▲ ▼ arrow keys
once again, scroll through and select which active Traffic Unit the user may want bridged or
backed up. Once selected, press ENTER to configure.
Figure A-13 illustrates the operational status of the front panel LEDs for a Redundant Unit and
two Traffic units (in this example, Traffic Units #1 and #2). In this example, Traffic Unit #2 is
being bridged in manual operating mode:
