22.3 Removing the XSCF BB Control Cable
This section describes the procedure for removing the XSCF BB control cable.
  1. Make a note of the XSCF BB control cable to be replaced.
    Log in to the XSCF and execute the showstatus command or showlogs error command. Then, make a note of the ports connected to the XSCF BB control cable to be replaced. For details on the commands, see "8.2.2 Identifying a Fault."
  1. The underlined part in the error example below indicates that an error has been found in the XSCF BB control cable connected to BB#00 and BB#01.

From the above error message and "Appendix A Lists of Cable Connections in a Building Block Configuration," identify the port number at the other end of the connection of the target XSCF BB control cable.
In this example, "BB01-XSCF0" is the port number at the other end.

  1. Write the port number on labels.
    The replacement XSCF BB control cable comes with the labels shown in Figure 22-2. Write the connected port on these labels. For the XSCF BB control cable, use LABEL-E. As in the example shown in Figure 22-2, write the connected port number identified in step 1 on two labels.

  1. Place the server in the cold state.
    To perform maintenance after every SPARC M12-2S was placed in the cold state without using the maintenance menu, remove the power cords of every SPARC M12-2S. For details on handling power cords, see "9.8.2 Removing the Power Cords."

  1. Remove the XSCF BB control cable.
    Pull out the XSCF BB control cable (in the direction of arrow 2 in Figure 22-4 and Figure 22-5) while pushing in the latches on both sides of the cable connector (in the directions of the arrows marked 1 in Figure 22-4 and Figure 22-5).
