Chapter 1 Xserve at a Glance 11
Serial console port
Connect a serial device or a computer with a serial port. This port supports RS-232 connections.
See “Using the Serial Port” on page 22.
Mini DisplayPort
You can connect a display to the Xserve using this port. If you have a DVI or VGA display, adapter
cables are available separately.
Expansion slots
You can install two PCI Express (PCI-E) expansion cards in the Xserve. Slot 1 accepts 6.6 inch cards.
Slot 2 accepts 9-inch cards. For information about installing cards, see the printed Xserve Setup Guide
that comes with the Xserve.
Gigabit Ethernet ports
Connect the Xserve to a high-speed Ethernet network using the two built-in Ethernet ports. Ethernet
ports adjust automatically to the transmission speed supported by the network. A green light in the
upper left corner of each port indicates whether that port is connected to a live Ethernet network;
a blue light on the right indicates activity.
Always connect an Ethernet cable to the right port (port 1) first.
USB 2.0 ports
Connect USB devices, such as a keyboard or mouse. A USB 2.0 port is also located on the front
panel. The enclosure lock must be unlocked for the Xserve to recognize some devices connected
to these ports.
Power supply and power supply bays
A removable power supply for the Xserve. The power cord connects here. You can install two 750-
watt power supplies for redundancy; either supply can take over the full load for the Xserve if the
other supply fails or is removed.
FireWire 800 ports
Connect FireWire devices to the Xserve. The enclosure lock must be unlocked for the Xserve to
recognize devices connected to these ports.
System information tag
The Xserve serial number and the hardware (MAC) addresses of its built-in Ethernet ports are printed
on this pullout tab. You’ll need the serial number when you install and set up the server software
remotely.
System identifier button and light
The yellow system identifier light flashes if a problem is detected. You can also turn it on manually by
pressing the button, or remotely using Server Monitor. This indicator is useful for locating a particular
unit in a rack with more than one Xserve. A second system identifier button and light are on the
front panel.
