4.3.2 Crossbar Cable Connections via a Crossbar Box


4.3.2 Crossbar Cable Connections via a Crossbar Box
Like the wiring of the XSCF cable, the crossbar cable is shipped connected to the SPARC M12-2S and the crossbar box.
In the 9BB configuration or over, wire the crossbar cable interconnecting racks from expansion rack 2 to expansion rack 1 and connect them to the respective ports.

Each cable has an attached label showing the connection destination port. Connect the cable to the port corresponding to the label.
Since one port number is assigned to each pair of ports, connect crossbar cables (optical) in pairs.
For the cable routes, see Figure 4-14.
When laying the cables, use the supplied hook-and-loop fastener strips to bundle them as appropriate.

  1. Unpack the cables that will pass between the racks.
    Using a hook-and-loop fastener, nylon band, or the like, the cables are tied to the side (A in Figure 4-12) or rear (B in Figure 4-12) of a rack with their connectors wrapped in a bag.
    a. Remove the cable connectors from the parts fixing them to the rack.

    b. Unwrap the cable connectors.

Figure 4-12 Cable storage locations in expansion rack 2
  1. Pass the crossbar cables unwrapped in step 1 between the upper and lower PDUs on the connecting part of the racks.
    Pass the crossbar cables connecting BB#00 to BB#03 and XB#80 through the lower side of the connecting part (A in Figure 4-13).
    Pass the crossbar cables connecting BB#04 to BB#07 and XB#81 through the upper side of the connecting part (B in Figure 4-13).

  1. Connect the crossbar cables to crossbar boxes.
    The crossbar cables are laid in a bundle for each chassis. Connect cables without changing how they are laid.
    Each cable has an attached label showing the connection destination port. Connect the cable to the port corresponding to the label.
    Since one port number is assigned to each pair of ports, connect crossbar cables (optical) in pairs.
    For the port locations, see Figure 4-16 and Figure 4-17, and for an example of the appearance of the label, see Figure 4-18.
    Hold the connector of the crossbar cable, and insert it straight into the opening. Do not hold the cable or its pull-tab part when inserting it.
Note - If you insert a connector with the pull-tab pulled, the connector may be damaged.
Note - There are two types of crossbar cable (optical). Connect crossbar cables of the same type to the same port numbers.
You can distinguish the type of crossbar cable by the pull-tab shape (A in Figure 4-15).

Figure 4-18  Example of the Appearance of a Crossbar Cable Label
Figure 4-18 Example of the Appearance of a Crossbar Cable Label
Note - The label shows both the cable connection destination and the unit connected by the cable.
  1. Confirm that the crossbar cables are correctly and firmly connected.
    With the crossbar cables connected to their ports, push in each cable while holding the joint (A in Figure 4-19) at the base of the crossbar cable connector.
Note - A loose crossbar cable connection may, on rare occasions, cause an error due to poor connection. After connecting a crossbar cable, push it in again so that it is tightly in place to prevent any improper connection. Do not hold only the fiber optic cable when performing the work at this time. Otherwise, the fiber optic cable may bend out of shape.
