58 Sun StorageTek 2500 Series Array Hardware Installation Guide • March 2007

Before you connect data hosts directly to the array,check that the following

prerequisites have been met:

■Interface cables are connected and between the HBAs and the array controllers.■SAS cables (1-, 3-, or 6-meters) are available to connect the array host ports to the

data host HBAs.

Each controller module on a controller tray has threeSAS host ports (FIGURE 3-11).

FIGURE3-11 SAS Data Host Ports (on back of tray).▼To Connect Data Hosts to a 2530 Array
1. Locate the host ports at the back of the controller tray (FIGURE 3-11).

If the host port has a plastic protection plug, remove it.

2. Connect one end of the SAS cable to a host port on a controller module.

Host ports are numbered from left to right: host port 1, host port 2, and host

port 3.

3. Connect the other end of each SAS cable to a data host HBA.

4. Affix a label to each end of the cable. See “Host Cable Labeling” on page 59 for

information about cable labels.

5. Repeat these steps for each host-to-controller connection.
