Note – Sun equipment conforms to the Ethernet 10Base-T standard, which
states that the 10BaseT Link Integrity Test function should always be enabled
on both the host and the hub. If you have problems verifying connection
between Sun equipment and your hub, verify that your hub also has the link
test function enabled. Refer to the Troubleshooting chapter in the
SPARCserver 1000 System Service Manual and the manual provided with your
hub for more information about the 10BaseT Link Integrity Test function.
2.6 Connecting an ASCII Terminal
An ASCII terminal (or workstation) must be connected to the server to display
diagnostic messages produced by the power-on self-test (POST) program. A
terminal is not required for normal server operation. If necessary, find a
terminal and connect it to the server. To connect an ASCII terminal:
1. Plug the terminal cable into serial port A on the system board in slot 0.
See Figure 2-7.
Note – Connect the terminal to the system board in card cage slot 0 ONLY!
