Configuring the Terminal Concentrator
This section describes the procedure for configuring the terminal concentrator's network addresses and ports.
How to Configure the Terminal Concentrator
From the administrative console, add the following entry to the /etc/remote file.
tc:\ :dv=/dev/term/a:br#9600:
Verify that the server and the terminal concentrator are powered on and that the cabinet keyswitch (if applicable) is in the ON position.
Establish a connection to the terminal concentrator's serial port:
# tip tc
Hold down the terminal concentrator Test button (Figure 2-6) until the power LED flashes (about three seconds), then release the Test button.
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.
Figure 2-6 Terminal Concentrator Test Button and LEDs

Observe the terminal concentrator front-panel LEDs:
If the front-panel LEDs light up as shown in Table 2-1, and the administrative console displays a monitor:: prompt, go to Step 7.
If the front-panel LEDs do not light up as shown in Table 2-1, or the administrative console does not display a monitor:: prompt, use Table 2-2 and the documentation that shipped with your terminal concentrator to troubleshoot the problem.

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: NAfter 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.
Use the ping(1M) command to confirm that the network connection works.
Exit the tip utility by pressing Return and typing a tilde, followed by a period.

Go to How to Set Terminal Concentrator Port Parameters.
How to Set Terminal Concentrator Port Parameters
This procedure explains how to determine if the port type variable must be set and how to set this variable.
The port type parameter must be set to dial_in. If the parameter is set to hardwired, the cluster console might be unable to detect when a port is already in use.
Locate the Sun serial number label on the top panel of the terminal concentrator (Figure 2-7).
Check if the serial number is in the lower serial-number range. The serial number consists of 7 digits, followed by a dash and 10 more digits.
If the numbers after the dash start with 9520 or higher, the port type variable is set correctly. Go to Step 4.
If the numbers after the dash start with 9519 or lower, you must change the port type variable. Go to Step 3.
Figure 2-7 Determining the Version From the Serial Number Label

Use the administrative console to change the port type variable to dial_in by setting the port parameters, then reboot the terminal concentrator as shown in the following example.
The boot command causes the changes to take effect. The terminal concentrator is unavailable for approximately one minute.

Verify that you can log in from the administrative console to the consoles of each node.
