McAfee® Network Security Platform 6.0 Cabling the heartbeat connection
cable connector type is indeed RJ45 and the maximum distance is that of standard twisted
pair (100 meters).
If desired, TX modules can be used to provide the failover connection. This is not
traditionally done, however, because the SX modules are less expensive and have a
greater maximum distance.
Note: The TX module can only be used at 1000 Mbps: there is currently no option to
run the TX module at 10/100 Mbps.
Cabling failover through a network device
Do not cable the heartbeat connection through an external network device!
To keep overhead low and throughput high, the Sensors do not include layer 2 or 3
headers on the packets they pass over the heartbeat connection, and they pass data
larger than the standard Ethernet maximum frame size (1518 bytes).
If you attempt to place a network device, such as a switch or router, between the heartbeat
ports, the heartbeat connection will fail.
