Notes:

1.

G means that the pin is jumpered to ground.

2.

- means that the pin is not jumpered.

SA means soft addressing.

Step 4. Change the Link Services of the Drive (optional)

You can optionally change the link services (for example, the speed and type of topology) of your Fibre Channel drive. If you choose not to alter the link services, the drive defaults to a negotiated speed and operation in an FC-AL topology with a direct connection to the server.

In the following procedure, note that:

vPin 5 is disconnected and is not represented in Table 7.

vPin 9 is ground.

To change the type of topology and the speed of the Fibre Channel drive:

__ 1. Determine the type of topology in which you want to operate the Ultrium 2 Tape Drive and refer to Table 7 for its corresponding pin configuration.

__ 2. Determine the speed at which you want the Ultrium 2 Tape Drive to operate and refer to Table 7 for its corresponding pin configuration.

__ 3. Locate the Fibre Channel (FC) configuration/status connector on the drive

(see	in Figure 7 on page 25).
__ 4. Place jumpers on the pins that you identified in steps 1 and 2.
