Chapter 5: System Configuration and Operation
Connecting Your Terminal
The SGI 2400 or 2800 rackmount server requires a customer-supplied American Standard
Code for Information Interchange (ASCII) terminal. Note the following caution before
attempting to connect your terminal.
Caution: Before plugging the terminal into either a 120 VAC or a 220 VAC outlet, be sure
that the electrical rating on the UL-CSA label is in either the 100 to 120 VAC or the 200 to
240 VAC range, whichever applies.
Note: When using a terminal in locations that do not have either a 120 VAC or a 220 VAC
outlet, contact your SGI system support engineer before plugging in the terminal power
cable. Use only the specified cable to connect the terminal to the system chassis.
The server uses PC-style serial cables. You cannot use older style SGI serial cables. See
“Standard Serial Ports” on page 38 for cable pinout information.
Note: This product requires the use of external shielded cables in order to maintain
compliance with Part 15 of the FCC rules. Serial cables from different vendors are not
compatible. Verify the pinout of your cable before making the connection.
Use the following procedure to connect the ASCII terminal to your system:
1. Go to the back of the system chassis and verify that the system power switch,
located in the lower right corner, is off (see Figure 5-7 as required).
2. Make sure that the power switch on the terminal is turned off and that the power
cord is not connected to an outlet.
3. Attach the end of the terminal cable with the 25-pin connector to the corresponding
connector at the rear of the terminal.
4. Locate the main module I/O panel at the rear of the chassis.
5. Attach the end of the cable with the 9-pin D-subconnector to the serial connector
labeled “Console Port” on the module I/O panel, as shown in Figure 5-1.
6. Attach the terminal power cord to the rear of the terminal and to the appropriate
power source.
Refer to IRIX Admin: System Configuration and Operation for more information about
configuring your terminal.
