Cabling the heartbeat connection

There is no standard heartbeat port across all McAfee

Network Security Sensor (Sensor)

models. Instead, the port or ports you use to connect the two Sensors for failover depends

directly on the model at hand. The details are as follows:

Sensor model Port(s) used for heartbeat connection

I-4010 6A and 6B (HA1 and HA2)

I-4000 2A and 2B

I-3000 6A and 6B (HA1 and HA2)

I-2700 4A

I-1400 R1 (response port)

I-1200 R1 (response port)

Sensor model Port(s) used for heartbeat connection

M-8000 3A and 3B (HA1 and HA2)

M-6050 4A (HA1—note that port 4B remains unused)

M-4050 2A

M-3050 2A

M-2750 10A

M-1450 4A

M-1250 4A

N-450 10A and 10B

Initial hints

Consider these hints when cabling:

• The I-3000, I-4000, I-4010, models require two ports to share flow information at a

high throughput level.

• Only port 4A is actually used for the heartbeat connection on the I-2700 model. Port

4B is disabled when in failover mode.

• Ports 6A and 6B are labeled HA1 and HA2, respectively, on the I-3000 and I-4010

models to indicate their use in the failover process. (HA stands for High Availability.)

• To cable the heartbeat connection on the I-1200 and I-1400 Sensors, connect the

Response ports of the primary and secondary using a crossover cable.
