Before You Begin
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.

Attach side brackets
Using a total of four #8-32 x 3/16 flathead Phillips screws (two per bracket), attach the side bracket to rear
mounting holes on each side of the chassis.

Rails Assembly
Note: The two rail kit installation pictorials immediately following show the left and right rails viewed
from the front and looking rearward. An assembly and an exploded view is provided for each rail.
Left Rail Assembly
Complete steps 1–3 to assemble the rails.
Note: Refer to callout 1 in Figure 3 below for the assembled left rail (ready for installation into the rack).
1. Slide the rear rail insert (callout 4, Figure 3 below) into the front rail sleeve (callout 2, Figure 3 below).

2. To determine the cabinet depth required by the rails, fit the rail assembly (callout 1) to the rack and note
which tapped holes in the rear rails align with the front rail’s slotted holes. If cage nuts are pre-installed,
remove them.

3. Using the measurements recorded in sub-step 2 above, select two or three #8-32 x 3/8 flathead Phillips
screws (depending on your cabinet depth) to loosely attach the rear rail insert (callout 4) to the front rail
sleeve (callout 2).
You will tighten the screws later.
Right Rail Assembly
Complete steps 1-3 above to assembly the right rail.

Install Rails (Square, Round, Pre-tapped
Hole-Racks)
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.
