Attaching cables to the Sensor Connect the cables for SPAN or hub mode 4 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 fiber-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 failover interconnection Failover requires connecting two identical M-2750 Sensors (same model, same software) using an interconnection cable or cables. Gigabit ports 10A is the failover interconnection port on the M-2750 Sensor. A failover cable is the only additional hardware required to support failover communication between two M-2750 Sensors. Task 1 Plug the cable appropriate for use with your SFP module into port 10A of the active Sensor. 2 Connect the other end of the cable to port 10A of the standby Sensor. Figure 4-2 M-2750 failover pair 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-2750 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. With the Bypass Switch in place, normal Sensor operation supplies power to the switch through a control cable. While the Sensor is operating, the switch is "on" and routes all traffic directly through the Sensor. When the Sensor fails, the switch automatically shifts to a bypass state: in-line traffic McAfee® Network Security Platform M-2750 Sensor Product Guide 27
