The service processor network management port (NET MGT port)
■
Power cables for the two system power supplies
■
Service processor management ports: There are two service processor
■
management ports for use with the ILOM service processor.
The service processor serial management port (labeled SER MGT) uses an
■
RJ-45 cable and is always available. This port is the default connection to the
ILOM service processor.
The service processor network management port (labeled NET MGT) is the
■
optional connection to the ILOM service processor. This port is not available
until you configure network settings for the service processor (through the
service processor serial management port). See
Network Management Port" on page
management port uses an RJ-45 cable for a 10/100 BASE-T connection. This
port does not support connections to Gigabit networks.
Ethernet ports are labeled NET0, NET1, NET2, and NET3. The Ethernet interfaces
■
operate at 10 Mbps, 100 Mbps, and 1000 Mbps.

TTY serial port: Use the 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 service processor 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 four USB controllers, for a total
■
of 504 USB devices per system.
AC power cables: Do not attach power cables to the 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 ILOM service processor initializes as soon as the AC power cables
are connected to the power source. System messages might be lost after 60 seconds
if the server is not connected to a terminal, PC, or workstation.
