PCI card slots
You can install two 12-inch PCI expansion cards in the two slots. (See “About PCI Cards for
the Server” in Chapter 5 of the
Xserve User’s Guide for more information about card
requirements.)
RAM expansion slots
You can expand DDR RAM up to 2 GB, using the four slots. (See “Adding Memory” in
Chapter 5 of the
Xserve User’s Guide for more information.)
Power supply
The auto-switching power supply detects the input voltage and adjusts for it. A thermal
control adjusts the speed of the power supply’s fan as needed.
Blowers
The blowers cool the server during operation. Sensors detect and report if a blower needs
service. Software adjusts the blower’s speed as necessary.
Chassis release latches
Press these latches to slide the server to its full length when in the rack, or to remove it
from the cover.
Serial number and Ethernet MAC address label
You must use the system’s serial number and the Ethernet MAC address when you install
and set up the server software. Write down these numbers and keep them in a safe place. A
duplicate of this label is on the back of the system, below the PCI card expansion slots.
