Chapter 1 Preparing for Installation 9
■Ethernet ports. The server Ethernet interfaces operate at 10 Mbps, 100 Mbps, and
1000 Mbps. The transfer rates for the Ethernet ports are given in TABLE1-1.
■TTYAserial port. Use the DB-9 connector with a null modem cable for serial
devices. This port appears as ttya in Solaris OS and OpenBoot PROM™
messages. This port is not connected to the SC serial management port.
■AC power cables. As soon as the AC power cables are connected to the power
source, the server goes into standby mode and the ALOM CMT system controller
initializes.
Tip – The serial terminal or a terminal emulator should be connected before you
connect the power cables. As soon as AC power is connected to the system, the
system controller immediately powers on and runs diagnostics. Diagnostic test
failures will be printed on the serial terminal. For more information, refer to the
Advanced Lights out Management (ALOM) CMT v1.x Guide.
Safety Precautions
Caution – Deploy the antitilt feature for your equipment rack before beginning the
installation.
