McAfee® Network Security Platform 6.0 Cabling the heartbeat connection
Important notes
• The monitoring ports and failover ports use the same GBIC. (There is no special GBIC
required for the heartbeat connection.)
• All GBICs and fiber optic cables are sold separately from the Sensors.
Note : McAfee only officially supports GBICs purchased from McAfee price list.
Cabling guidelines and examples
The following is a quick summary of the rules for cabling the heartbeat connection:
• The cabling must always cross the Tx and Rx channels between the Sensor heartbeat
ports. It is for this reason the I-1200 and I-1400 Sensors, for example, require a
crossover cable between their failover pairs.
• When 2 ports are used on each Sensor for the heartbeat connection, you must always
cable between identical port names. For example, port 2A on Sensor 1 should always
be cabled to port 2A on Sensor 2 (not 2B).
Some sample hardware requirements and setup hints are given in the following sections:
I-1200 and I-1400 examples
A pair of I-1200 or I-1400 Sensors located within 100 meters or less of each other would
require:
• One (1) CAT 5 crossover cable
Connect the crossover cable to each response port.
I-2700 examples
A pair of I-2700 Sensors located within 550 meters of each other would require:
• Two (2) standard SX GBICs
• One (1) SX fiber optic cable with SC connectors
You need 2 GBICs and a single cable because I-2700 Sensors only use port 4A for
Sensor-to-Sensor communication.
