Introduction
Overview
See Figure 1-2 on page 5 for component location.
The mass storage section located in the front allows access to the hard disk drives without removal of the
bezel (bezel removed in figure). Removing the bezel allows access to the removable media drive, the front fans
and the bulk power supplies. The mass storage bay accomodates one 5.25-inch removable media drive and up
to four 3.5-inch hard disk drives. The front panel display, containing LEDs and the system power switch, is
located directly above the removable media drive bay.
Below the mass storage section and behind the removable bezel are two PCI DC-to-DC power supplies. Each
PCI power supply will provide power requirements for only one PCI-X I/O partition.
The PCI-X card section, located in upper rear of server, is accessed by removing top cover (cover shown
removed).
Six PCI-X OLR fan modules are located opposite the PCI-X card bulkheads. They are housed in blue plastic
carriers.
Four OLR N+1 system fan modules are externally attached to the chassis. Two are mounted on the front
surface of the chassis and two are mounted on the rear surface of the chassis.
When facing the front of the server, the cell boards are located on the right side of the product behind a
removable side cover (cover removed in figure). Rack cabinet front doors are often times hinged on the left,
which restricts the cell board to be extracted or inserted from the right.
The bulk power supply is partitioned through the use of a sealed metallic enclosure located in the bottom of
the server. This enclosure houses the N+1 fully redundant bulk power supplies. These power supplies are
installed from the front of the server after removing the front bezel.
