Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS

ProcedureHow to Configure the Terminal Concentrator

  1. From the administrative console, add the following entry to the /etc/remote file.


    tc:\
    :dv=/dev/term/a:br#9600:
    
  2. Verify that the server and the terminal concentrator are powered on and that the cabinet keyswitch (if applicable) is in the ON position.

  3. Establish a connection to the terminal concentrator's serial port:


    # tip tc
    
  4. Hold down the terminal concentrator Test button (Figure 2–6) until the power LED flashes (about three seconds), then release the Test button.

  5. Hold down the terminal concentrator Test button again for one second, then release it.

    The terminal concentrator performs a self-test, which lasts about 30 seconds. Messages display on the administrative console. If the network connection is not found, press the Q key to stop the message.

    Illustration: The preceding context describes the graphic.

  6. Observe the terminal concentrator front-panel LEDs and use the information in the following table to decide your course of action.

    Power (Green) 

    Unit (Green) 

    Net (Green) 

    Attn (Amber) 

    Load (Green) 

    Active (Green) 

    Test (Orange) 

    ON 

    ON 

    ON 

    ON 

    OFF 

    Intermittent blinking 

    ON 

    • If the front-panel LEDs light up as shown in the table above and the administrative console displays a monitor:: prompt, go to Step 7.

    • If the front-panel LEDs do not light up as shown in the table above, or the administrative console does not display a monitor:: prompt, use the following table and the documentation that shipped with your terminal concentrator to troubleshoot the problem.

      Other failure 

      One or more Status LEDs (1-8) are ON 

       

       

       

       

       

  7. Use the addr command to assign an IP address, subnet mask, and network address to the terminal concentrator.

    In the following example (Class B network, Class C subnet), the broadcast address is the terminal concentrator's address with the host portion set to 255 (all binary 1's).


    monitor:: addr
    Enter Internet address [<uninitialized>]:: 172.25.80.6
     Internet address: 172.25.80.6
    Enter Subnet mask [255.255.0.0]:: 255.255.255.0
     Subnet mask: 255.255.255.0
    Enter Preferred load host Internet address [<any host>]:: 172.25.80.6
    *** Warning: Load host and Internet address are the same ***
     Preferred load host address: 172.25.80.6
    Enter Broadcast address [0.0.0.0]:: 172.25.80.255
     Broadcast address: 172.25.80.255
    Enter Preferred dump address [0.0.0.0]:: 172.25.80.6
     Preferred dump address: 172.25.80.6
    Select type of IP packet encapsulation (ieee802/ethernet) [<ethernet>]:: 
     		Type of IP packet encapsulation: <ethernet>
    Load Broadcast Y/N [Y]:: n
        		Load Broadcast: N
  8. After you finish the addr session, power-cycle the terminal concentrator.

    The Load and Active LEDs should briefly blink, then the Load LED should turn off.

  9. Use the ping(1M) command to confirm that the network connection works.

  10. Exit the tip utility by pressing Return and typing a tilde, followed by a period.


    <Return>~.
