■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
