Chapter 1 Preparing for Installation 7
■ Ethernet ports are labeled NET0, NET1, NET2, and NET3. The 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 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.
Port Locations for Both Servers

T5120 server.
