Connect the cables for SPAN or hub mode
For the Sensor, monitoring in SPAN or hub mode occurs in in-line fail-open mode. When you monitor in SPAN or
hub mode, you use only single ports.
To connect an Sensor to a SPAN port or hub, plug an LC ber-optic or 45 cable into one of the modules and
connect the other end of the cable to the SPAN port or the hub.
Cable the fail-over interconnection
Before you begin
To enable fail-over communication between two M-2850/M-2950 Sensors, you will require ber or
copper SFPs and an LC-LC or RJ45-RJ45 cable as a fail-over cable.
Fail-over requires connecting two identical M-2850/M-2950 Sensors (same model, same software) using an
interconnection cable or cables. Gigabit port 6A is the fail-over interconnection port on the M-2850/M-2950
Sensors.
Task
1
Plug the cable appropriate for use with your SFP module into port 6A of the M-2850/M-2950 of the active
Sensor.
2
Connect the other end of the cable to port 6A of the M-2850/M-2950 of the standby Sensor.

About the fail-open hardware
The standard Gigabit Fail-Open Kit (sold separately) minimizes the potential risks of in-line Sensor failure on
critical network links. Both copper and optical versions of the Kit are available for 1 Gigabit ports.
The Monitoring ports on M-2850/M-2950 fail-close; thus, if the Sensor is deployed in-line, a hardware failure
results in network downtime. Fail-open operation for the Monitoring ports requires the use of the optional
external Bypass Switch provided in the Kit.
