Connecting the SAS interface cable

Edit online

Each tape drive is required to have a dedicated bus to the initiator, referred to as point-to-point connection. SAS architecture does not support multiple tape drives connected to a single host adapter port. The maximum SAS cable length that can be used to connect the host adapter to the tape drive varies depending on the type of SAS connection. See Optional features for the maximum cable length that can be used.

To connect the cable:

  1. Ensure that the tape drive is powered OFF.
  2. Since there are several types of SAS connectors, verify that the SAS cable has the correct connectors for the SAS host adapter and for the tape drive.
  3. The tape drive has two SAS ports and can be connected to two servers. Refer to the appropriate figure that represents your configuration for cabling information (see Figure 1 or Figure 2). Then, connect the SAS cables to SAS host adapters and to the tape drive as shown.

  4. Ensure that the host adapter and the server are configured correctly for a SAS bus operation. Refer to the host adapter and server documentation for instructions.
  5. If the power cord is already installed, turn power to the tape drive ON.
