■
The SC serial management port (labeled SERIAL MGT) uses an RJ-45 cable
and is always available. This is the default connection to the ALOM-CMT
system controller.
■
The SC network management port (labeled NET MGT) is the optional
connection to the ALOM-CMT system controller. This port is not available
until you have configured network settings for the system controller (through
the SC serial management port). See
“Enabling the System Controller Network
Management Port” on page 38 . The SC network management port uses an
RJ-45 cable for a 10/100 BASE-T connection. This port does not support
connections to Gigabit networks.
■
See the Sun Fire T2000 Server Overview for more information.
■
Ethernet ports are labeled NET0, NET1, NET2, and NET3. The Sun Fire T2000
Ethernet interfaces operate at 10 Mbps, 100 Mbps, and 1000 Mbps. The transfer
rates for the Ethernet ports are given in
TABLE 1-1
.
■
TTYA serial port: Use the Sun Fire T2000 DB-9 connector with a null modem
cable for serial devices. This port appears as
ttya
in Solaris OS and OpenBoot
messages. This port is not connected to the SC serial management port.
■
USB Ports: USB ports support hot-plugging. You can connect and disconnect USB
cables and peripheral devices while the system is running, without affecting
system operations.
■
You can only perform USB hot-plug operations while the OS is running. USB
hot-plug operations are not supported when the system
ok
prompt is
displayed or before the system has completed booting.
■
You can connect up to 126 devices to each of the two USB controllers, for a
total of 252 USB devices per system.
■
AC power cables: Do not attach power cables to the Sun Fire T2000 power
supplies until you have finished connecting the data cables, and have connected
the server to a serial terminal or a terminal emulator (PC or workstation). The
server goes into standby mode and the ALOM-CMT system controller initializes
as soon as the AC power cables are connected to the power source. System
messages may be lost after 60 seconds if the server is not connected to a terminal,
PC, or workstation.
