Note – Before you begin, ensure that the tworequired Ethernet cables are available. These requirements are outlined in the StorageTek 2500 Series Array Site Preparation Guide.

There are three ways to establish a connection between the management host and Ethernet port 1 of an array controller:

“Attaching the Ethernet Ports to the LAN of the Management Host” on page 50

“Attaching the Ethernet Ports to the Management Host Using an Ethernet Hub” on page 51

“Attaching the Ethernet Ports Directly to the Management Host With a Cross- Over Cable” on page 51

Attaching the Ethernet Ports to the LAN of the Management Host

To attach the Ethernet ports to the local area network (LAN) of the management host:

1.Locate the Ethernet port for Controller A and Controller B at the back of the controller tray (FIGURE 3-1).

2.Connect Ethernet cables to the Ethernet ports of each controller.

3.Connect the other end of each Ethernet cable to the LAN on which your management host resides (preferably on the same subnet).
