23Chapter 2 Installing or Replacing Components

Power supply bays

You can install one or two power supplies in the Xserve. When two supplies are installed,

they share the load. If one supply fails, the other takes over the full load. See “Installing or

Replacing a Power Supply” on page 28.

Expansion slots

You can install a half-length (6.6 inch) PCI-E card in slot 1 and a 9 inch PCI-E card in slot 2.

See “Installing a PCI Express Card” on page 38.

DIMM slots

You can install up to twelve error-correcting dual inline memory modules (DIMMs) in

these slots. See “Adding Memory” on page 33.

Fan array

The fan array draws cooling air through the Xserve from front to back.

Drive bays

You can install SATA (Serial ATA) Apple Drive Modules or qualied third-party SAS (Serial

Attached SCSI) drive modules. See “Installing or Replacing a Drive Module” on page 24.

Solid-state drive (SSD)

If you ordered your system with an SSD, the Xserve comes with the SSD set up as the

startup disk.

Rack release latch

This latch stops the Xserve about halfway out of the rack. Press to release.

Battery

The battery on the main logic board powers the system clock and preserves basic

system settings (in NVRAM) when power supplies are disconnected. See “Replacing the

Battery” on page 43.
