Note – Sun equipment conforms to the Ethernet 10/100BASE-T standard,
which states that the 10/100BASE-T 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 Section 8.6.1, “Failure of Network
Communications,” in the Ultra Enterprise 3000 System Manual (p/n 802-6051),
and refer to the manual provided with your hub for more information about
the Link Integrity Test function.
6. If all cables are connected, power on the system.
2.5 Connecting an ASCII Terminal
An ASCII terminal (or workstation) must be attached to the server to display
diagnostic messages produced by the firmware (power-on self test /POST or
OpenBoot™ PROM/OBP) program. A terminal is not required for normal
server operations, so it may be necessary to find a terminal to connect to the
server.
1. Connect the terminal cable into serial port A on the clock board.
See Figure 2-7.
