1.4 SAS Connectors and
Cabling
Use a separate crossover cable for each server, JBOD, RAID array, switch, or other device
connected to the SAS6160 switch. Use Mini SAS 4x connectors (also called SFF-8088
connectors) on both ends of the crossover cables to connect the switch to all devices.
The keyed connectors at port 0 and port 2, located at the upper left on the SAS6160
switch, support active cabling. This allows longer cable lengths and requires a special
type of cable. These cables are keyed so that they do not attach to a passive connector.
However, you can attach a passive cable to a connector that supports active cabling.
Chapter 2, Installation and Hardware Setup provides information about recommended
cable lengths.
The following figure shows a crossover cable with Mini SAS 4x connectors on both
ends.

All cables used with the SAS6160 switch must comply with the SAS 2.1 standard.
