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.
For information, see “Removing or Installing a Power Supply” on page 28.
Battery
The battery on the main logic board powers the system clock and preserves basic
system settings (in NVRAM) when power supplies are disconnected. For
information, see “Replacing the Battery” on page 44.
PCI-X and PCI-E card slot (slot 1)
You can install a full-length (9 inch) PCI-X or PCI-E card in this slot using the
appropriate riser. For information, see “Installing a PCI Card” on page 38.
PCI-E slot (slot 2)
You can install a half-length (6.6 inch) PCI-E expansion card in this slot using a
PCI-E riser. For information, see “Installing a PCI Card” on page 38.
DIMM slots
You can expand memory in the Xserve up to 32 gigabytes (GB) by installing pairs
of fully buffered, error-correcting dual inline memory modules (FB-DIMMs) in
these slots. For information, see “Adding Memory” on page 33.
Fan array
The fan array draws cooling air through the Xserve from front to back.
Rack release latch
This latch stops the Xserve about halfway out of the rack. Press to release.
Drive bays
You can install SAS (Serial Attached SCSI) and SATA (Serial ATA) drives. For
information, see “Installing or Replacing an Apple Drive Module” on page 24.
