Attaching cables to the Sensor Cable the Sensor to monitor in SPAN or hub mode 4 Cable the Sensor to monitor in SPAN or hub mode When you monitor in SPAN or hub mode, you can use single ports. Task 1 Plug a Cat 5/ Cat 5e cable into one of the monitoring ports. 2 Connect the other end of the cable to the SPAN port or the hub. See Cable types for routers, switches, hubs, and PCs to determine which cable type to use with which type of network device. See also Cable types for routers, switches, hubs, and PCs on page 22 How to use peer ports on page 21 About connecting Sensors for fail-over Fail-over requires connecting two identical Sensors of the same model and same software version through an interconnection cable or cables. Previously, the creation of Sensor fail-over pair was allowed only if all the primary Sensor's monitoring port pairs were in in-line mode. Now, the flexibility to create a fail-over pair even if the primary Sensor has some of its monitoring port pairs in non-Inline (tap or SPAN) mode, is provided. For example, in an M-1450, you may have port pairs 1A-1B configured in in-line mode and ports 2A and 3A configured in SPAN mode. M-1250/1450 Sensors support TCP reset even when connected in tap mode. Cable M-1250/M-1450 Sensor for failover Gigabit port 4A is the failover interconnection port on the M-1250/M-1450 Sensor. A crossover failover cable is the only additional hardware required to support failover communication between two Sensors. Task 1 Plug a Cat 5/Cat 5e crossover cable into port 4A of the active Sensor. 2 Connect the other end of the cable to the port 4A of the standby Sensor.
