21.3 Removing the XSCF DUAL Control Cable


21.3 Removing the XSCF DUAL Control Cable
This section describes the procedure for removing the XSCF DUAL control cable.
  1. Make a note of the XSCF DUAL 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 DUAL 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 DUAL control cable connected to BB#00 and BB#01.

FRU: /BB#00/SCF_DUAL
Msg: Board control error (MBC link error)
  1. 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 DUAL control cable.
    In this example, "BB01-DUAL" is the port number at the other end.

  1. Write the port number on labels.
    The replacement XSCF DUAL control cable comes with the labels shown in Figure 21-3. Write the connected port on these labels. For the XSCF DUAL control cable, use LABEL-E. As in the example shown in Figure 21-3, write the 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."

Caution - Do not pull the XSCF DUAL control cable itself. Otherwise, the cable may be damaged and the system may fail to operate normally.
  1. Remove the XSCF DUAL control cable from the other chassis.
    Pull out the XSCF DUAL control cable (in the direction of arrow 2 in Figure 21-6) while pushing in the latches on both sides of the cable (in the directions of the arrows marked 1 in Figure 21-6).
