How to Cable the Terminal Concentrator

  1. Connect the serial cable (530-2152-01 or 530-2151-01) from serial port A on the administrative console to serial port 1 on the terminal concentrator, as shown in Figure 2-5.

    The cable connection from the administrative console enables you to configure the terminal concentrator. The connection serves no other purpose. You can remove this connection after you set up the terminal concentrator.

  2. Connect the nodes to the terminal concentrator. Use serial cables with an RJ-45 connector on one end and a DB-25 on the other.

    The cable connections from the concentrator to the nodes enable you to access the ok prompt or OpenBootTM PROM (OBP) mode by using the Cluster Console (Console Mode) Windows from the Cluster Control Panel (CCP). For more information on using the CCP, see Sun Cluster 3.0 System Administration Guide.

  3. Connect the public network Ethernet cable to the appropriate connector on the terminal concentrator.

    Note -

    The terminal concentrator requires a 10­-Mbit/sec Ethernet connection.

  4. Close the terminal concentrator bracket, and install screws in holes 8 and 29 on the left-side rail.
