Service processor management ports: There are two service processor management ports for use with 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 Enable the Service Processor Network Management Port.
The service processor 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 SPARC Enterprise T5140 and T5240 Servers Overview for more information.
Ethernet ports are labeled NET0, NET1, NET2, and NET3. The Ethernet interfaces operate at 10 Mbps, 100 Mbps, and 1000 Mbps. The table below shows the transfer rates for the Ethernet ports.
Table 15 Ethernet Connection Transfer Rates
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.
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.
