How 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.

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 9.
   • If the front-panel LEDs do not light up as shown in the table above, or the administrative console does not display the prompt monitor::, use the following table and the documentation that shipped with your terminal concentrator to troubleshoot the problem.

     Mode Power (Green) Unit (Green) Net (Green) Attn (Amber) Load (Green) Active (Green) Hardware failure ON Blinking OFF Blinking OFF OFF Network test failure ON ON Blinking OFF OFF Intermittent blinking Network test aborted, or net command failed ON ON OFF Blinking OFF Intermittent blinking Booted wrong image ON ON ON Blinking OFF OFF 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>~.
