Power socket
The power cord connects here; it is held in place by a special clip so that it stays
connected when the server is opened in the rack.
System identifier button and light
The system identifier light turns on if a problem is detected. It also can be turned on
manually by pressing the button. This indicator is useful for locating a particular unit in a
rack with multiple servers. A duplicate system identifier button and light are on the front
panel.

Gigabit Ethernet ports
Connect your server to a high-speed Ethernet network using the two built-in Ethernet
ports. Ethernet ports adjust automatically to the transmission speed supported by
network components. A green light to the left of each port indicateswhether that port is
connected to an Ethernet network; a blue light to the right of each port indicates activity.
Always connect an Ethernet cable to the lower port (port 1) first. See “Install the Cable-
Management Arm and Cables” on page 37 and “Connect Cables Directly to the Server”
on page 54 for details on connecting an Ethernet cable.
FireWire 800 ports
Connect FireWire devices to the server. A FireWire 400 port is also located on the front
panel. The enclosure lock must be unlocked for the server to recognize some devices
connected to this port. (See “FireWire Specifications” on page 86 for information about
FireWire ports and connectors.)
USB 2.0 ports
Connect USB devices, such as a keyboard or mouse. The enclosure lock must be unlocked
for the server to recognize some devices connected to these ports.
Serial console port
Connect a serial device or computer with a serial port. This console supports RS-232–
compatible connections.
PCI-X card slots
You can install two PCI -X cards in the server to connect peripheral devices. See “About
PCI-X Cards for the Server” on page 79 for details. One or both slots may come with cards
installed at the factory. An optional video card for connecting a monitor can be installed
in one of the PCI-X slots.
Serial number label
You must use the system’s serial number when you install and set up the server software.
Write down this number and keep it in a safe place. A label with the Ethernet MAC
address is also on the back panel.
