Routing and connecting the expansion rack SAS cables

Procedure

  1. Find and uncoil the SAS cables at the rear of the expansion rack being installed.
  2. Determine the destination rack and I/O enclosure for each SAS cable.
    1. Find the location code label at the free end of each SAS cable.
    2. Refer to Figure 1 and Figure 2 to translate the destination I/O enclosure location.

  3. Route the SAS cables to the destination rack.
    1. Do not connect the SAS cables to the I/O enclosure device adapter cards until directed later in this procedure.
    2. Route each cable  1  to the destination rack through the rack to rack holes at the upper rear of each rack. See and Figure 3 and Figure 4.

  4. Route the SAS cables to the destination I/O enclosures.
    1. Do not connect the SAS cables to the I/O enclosure device adapter cards until directed later in this procedure.
    2. SAS cables that will connect to an I/O enclosure on the left side of the rack are routed down the left side of the rack.
      • Left side cables have "XI1" or "XI3" in the location code (for example, Rx-XI3-P1-Cx-Tx), or the second character in the connection designator is uppercase (for example, 10A1).
    3. SAS cables that will connect to an I/O enclosure on the right side of the rack are routed down the right side of the rack.
      • Right side cables have "XI2" or "XI4" in the location code (for example, Rx-XI4-P1-Cx-Tx), or the last character in the connection designator is lowercase (for example, 10a1).
  5. Plug the SAS cables into the connectors on the I/O enclosure device adapter cards as indicated on the cable labels. Refer to Figure 5 and Figure 6 for connector locations.

    Note: Enclosures 1B1, 1B2, 2B1, and 2B2 are not present in models 980, 984 (except all-flash), 98B, 84E.

  6. Use existing cable ties to secure the cables neatly.
