Netra CT Server Service Manual

One way to power on and off your server is to log in to the server either remotely, where you log in to the Netra CT server as superuser through another server on the network, or directly, where you connect a terminal console to your Netra CT server. A terminal console can be an ASCII terminal, workstation, or PC laptop.

For a direct login, the connection to use varies depending on the Netra CT server model, the terminal console type, and the board you are connecting to:

• If you are using an ASCII terminal to power on and off a Netra CT server, go to Section B.1, To Use an ASCII Terminal.
• If you are using a Solaris workstation to power on and off a Netra CT server, go to Section B.2, To Use a Solaris Workstation.
• If you are using a PC laptop to power on and off a Netra CT server, go to Section B.3, To Use a PC Laptop.

B.1 To Use an ASCII Terminal

1. Obtain the appropriate cables and adapters and make the necessary connections.

You might need one or more cables and adapters to connect the ASCII terminal to the server. The cables and adapters you need vary, depending on the server model and the board that you are connecting to.

• If you are connecting an ASCII terminal to a CPU board or rear transition module, use the information in TABLE B-1 to make the necessary connections.
• If you are connecting an ASCII terminal to an alarm card or alarm rear transition module, use the information in TABLE B-2 to make the necessary connections.



TABLE B-1 Connecting an ASCII Terminal to a CPU Board or Rear Transition Module

Server Type	TTY A Port on Netra CT Server	Adapter	Cable	Adapter	Serial Port on Terminal
Netra CT 810 server	DB-9 male on the rear transition module. See Section A.2, Host Rear Transition Modules.	Not needed	DB-9 female-to-DB-25 male straight-through	DB-25 female-to-DB-25 female gender changer	DB-25 male
Netra CT 410 server	DB-9 male on the rear transition module. See Section A.2, Host Rear Transition Modules.	Not needed	DB-9 female-to-DB-25 male straight-through	DB-25 female-to-DB-25 female gender changer	DB-25 male

2. Access the "Set Up Menu" of the ASCII terminal and bring up the Serial Communications section.

3. Set up the serial port communications parameters.

The default settings should match the values reported on the host serial port.

• Hardwired modem connection
• No parity
• 9600 baud
• 1 stop bit
• 8-bit data

4. Test the connection.

Verify that communication is established to the server and the keyboard/display of the ASCII terminal.

B.2 To Use a Solaris Workstation

1. Get the appropriate cables and adapters and make the necessary connections.

You might need one or more cables and adapters to connect a Solaris workstation to the server. The cables and adapters you need vary, depending on the server model and the board that you are connecting to.

• If you are connecting a Solaris workstation to a CPU board or rear transition module, use the information in TABLE B-3 to make the necessary connections.
• If you are connecting a Solaris workstation to an alarm card or alarm rear transition module, use the information in TABLE B-4 to make the necessary connections.



TABLE B-3 Connecting a Solaris Workstation to a CPU Board or Rear Transition Module

Server Type	TTY A Port on Netra CT Server	Adapter	Cable	Adapter	Serial Port on Workstation
Netra CT 810 server	DB-9 male on the rear transition module. See Section A.2, Host Rear Transition Modules.	Not needed	DB-9 female-to-DB-25 male null modem	Not needed	DB-25 female
Netra CT 410 server	DB-9 male on the rear transition module. See Section A.2, Host Rear Transition Modules.	Not needed	DB-9 female-to-DB-25 male null modem	Not needed	DB-25 female

2. Check the /etc/remote file for the appropriate line.

To connect to the TTY A or COM 1 port on the workstation, check for:

tip -9600 /dev/ttya

3. Enter tip hardwire at the prompt.

The response should be the word connected.

To disconnect the tip window, enter ~. (tilde period) at the prompt.

B.3 To Use a PC Laptop

1. Get the appropriate cables and adapters and make the necessary connections.

You might need one or more cables and adapters to connect a PC laptop to the server. The cables and adapters you need vary, depending on the model server you have and the board that you are connecting to.

• If you are connecting a PC laptop to a CPU board or rear transition module, use the information in TABLE B-5 to make the necessary connections.
• If you are connecting a PC laptop to an alarm card or alarm rear transition module, use the information in TABLE B-6 to make the necessary connections.



TABLE B-5 Connecting a PC Laptop to a CPU Board or Rear Transition Module

Server Type	TTY A Port on Netra CT Server	Adapter	Cable	Adapter	Serial Port on PC Laptop
Netra CT 810 server	Rear-access model: DB-9 male on the rear transition module. See Section A.2, Host Rear Transition Modules.	Not needed	DB-9 female-to-DB-9 female null modem	Not needed	DB-9 male
Netra CT 410 server	Front-access model: DIN-8 female on the module. See Section A.1, Host CPU Boards. Rear-access model: DB-9 male on the rear transition module. See Section A.2, Host Rear Transition Modules.	Not needed	Front-access model: DIN-8 male-to-DB-25 male Rear-access model: DB-9 female-to-DB-9 female null modem	Front-access model: DB-25 female-to-DB-9 female Rear-access model: Adapter not needed	DB-9 male

2. Set the following connection parameters:

• No parity
• 9600 baud
• 1 stop bit
• 8-bit data
