11.3 Removing a Crossbar Cable (Optical)
This section describes the procedure for removing the crossbar cables (optical).
Enable the removal of the crossbar cables (optical) before attempting to remove them. For details, see "Chapter 7 Maintenance Flow."
Caution - Before you handle the crossbar control cables (optical), wear a wrist strap to ground any static electricity. If you perform this procedure without a wrist strap, individual components or the overall system may be damaged. For details, see "1.4 Notes Regarding Static Electricity."
  1. Remove the two crossbar cables (optical) from the chassis of the physical partition.
    Remove the crossbar cable (optical) by holding the tab (Figure 11-7 and A in Figure 11-8) of the cable and pulling it straight in the direction of the arrow. At this time, do not hold the cable part when pulling the crossbar cable.
Caution - Pulling the cable part without the connector lock completely released may cause damage.

Figure 11-8  Removing the Crossbar Cables (Optical) (SPARC M10-4S)
Figure 11-8 Removing the Crossbar Cables (Optical) (SPARC M10-4S)
  1. Remove the other pair of crossbar cables (optical) from the crossbar box.
    Remove the crossbar cable (optical) by holding the tab (A in Figure 11-9) of the cable and pulling it straight in the direction of the arrow. At this time, do not hold the cable part when pulling the crossbar cable.
Caution - Pulling the cable part without the connector lock completely released may cause damage.
Note - There is no problem if you remove the crossbar cables at the crossbar box while electricity is supplied.
Note - The cables on the rear of the crossbar box are bundled together and fastened to the right-hand cable support with a hook-and-loop fastener. Therefore, to remove the crossbar cables (optical), remove the hook-and-loop fastener from the cable support.
