Before You Begin
These instructions are for the following systems:
l QXS-448
l QXS-648
Complete the following:
l Verify that the installation site meets the chassis’s requirements for space and airflow, temperature, and
power (see the web-posted setup guide for your chassis).
l Considering your system configuration and weight distribution, determine where you will install each
chassis within the rack or cabinet. Install the first chassis in the lowest rack space you plan to use. Install
each remaining chassis into the next-higher available space within the rack, until all chassis are secured
in place.
l Confirm that you have cables of appropriate type and length to connect to hosts and to power outlets.
Caution: Be sure you are properly grounded before touching a static-sensitive component to minimize
potential for electronic discharge.
The person using these instructions must be qualified to service and install storage products.
Caution: Two people are needed to lift and move the chassis. Use care to avoid injury.
Required Tools
Required tools include:
l #2 Phillips screwdriver
l Antistatic protection devices.

This section provides the rail installation of three different types of racks. Information is as follows:
l Square Hole-Rack Rail Installation below
l Round Hole-Rack Rail Installation on page 12
l Pre-tapped Hole-Rack Rail Installation on page 16
Square Hole-Rack Rail Installation
Complete steps 1–4 to install the rails.
1. For square-hole racks, install cage nuts in the front rack holes where chassis ears will be attached.
a. Before rail installation, refer to Figure 5 below for location of screws and cage nuts for the front
of the chassis.

b. Before rail installation, refer to Figure 6 on the next page for location of screws and cage nuts for
the rear of the chassis.

Note: If you insert the cage nuts incorrectly, use a Cage Nut Removal Tool to easily remove the
cage nuts from the rack holes.
Position the rail's front and back mounting flanges so that through holes align with corresponding rack
holes, and note the locations.
Note: Align the bottom of the rail with the bottom of the rack unit where you would like to install the
rails. Rails should not be installed where the rail will straddle rack units (U). Most racks provide
alignment markers indicating the rack units used for rail installation.
Attach two cage nuts at the front of the rack, and two at the rear, per the red "X" marks shown in the
following installation detail views (Figure 7 on the next page).
Note: The rail kit supports either the RAID (controller) or expansion chassis.
On the following diagram, elevation numbers are arbitrary and represent vertical location within the
rack.The 1U rack heights are shown next to cage nut installation locations.

Install and Secure the Chassis
1. Carefully lift/align the chassis and slide it into the rack. Ensure that the chassis is level.
Caution:
hChassis must be level (parallel to floor).
h Rails might bend if the chassis is not level when inserted.
h Replace the rail if it becomes deformed as a result of inserting the chassis in an unlevel position
during installation.
Note: The top of the chassis might have a protective film installed. Leave the protective film on the
chassis. If the protective film does not allow the chassis to be installed (clearance issue in rack),
remove the protective film and discard.
