Connecting Cluster Cables
Two Category 6A Ethernet cables with RJ-45 connectors are provided: one green and one red.
Each cable is 2.5 meters in length.
■
Connect either the green cable or the red cable from Ethernet port 0 of one controller to
Ethernet port 0 of the other controller.
■
Connect the other cable from Ethernet port 1 of one controller to Ethernet port 1 of the other
controller.
The following figure shows cluster cabling between two ZS9-2 controllers (high-end model
shown).

Connecting Cluster Cables for ZS7-2, ZS5-x, ZS4-
4, ZS3-x, and 7x20 Controllers
ZS7-2, ZS5-x, ZS4-4, ZS3-x, and 7x20 controllers employ serial-based clustering using two
serial cluster links, and provide Ethernet connectivity via one link. The Ethernet link provides a
higher-performance transport for non-heartbeat messages, such as rejoin synchronization, and
provides a backup heartbeat.
The cables between the serial ports form a crossover pattern: 0 to 1 and 1 to 0. This crossover
cabling enables the use of straight-through cables between two identical controllers.
For details about the cluster interface cards, see ZS7-2, ZS5-4, ZS5-2, ZS4-4, ZS3-4, and 7x20
