Steps for Mounting an Array in a Rack

Follow these steps to mount a PS4000 array in a rack:
1. Change the mounting rail hardware, if necessary.
2. Determine where to place the mounting rails in the rack.
3. Attach the mounting rails to the rack.
4. Slide the chassis into the rack.
5. Attach the chassis to the brackets on the mounting rails and to the front of the mounting rails.
6. Install the bezel.
These steps are described in detail in the following sections. After you mount the array in the rack, see the
Installation and Setup manual for information about completing the array hardware installation.

Step 1: Change the Mounting Rail Hardware

The mounting rails are shipped with hardware pre-installed for mounting in a rack with square holes. If
you have a square-hole rack, no changes are necessary. Proceed with Step 2: Determine Where to Place
the Mounting Rails in the Rack.
If your rack has round or tapped holes, change the hardware as follows.
•
For round hole racks:
-
On the front and back of both mounting rails, remove the pre-installed locator pins and replace
them with the locator pins from the bag labeled ROUND. Insert the locator pins from the front,
using the same orientation as the pre-installed pins.
•
For tapped hole racks:
1. On the front and back of both mounting rails, remove the pre-installed locator pins.
2. Re-install the same locator pins from the opposite side of the holes you removed them from, so
that the pin protrudes from the front and rear of the mounting rail flanges.

Step 2: Determine Where to Place the Mounting Rails in the Rack

Make sure there is enough space in the rack for a 3U chassis. In a standard rack, the height of a 3U
chassis will span 9 holes.
Figure 1 shows the location of the top and bottom of the chassis relative to the location of the screws used
to attach the rail and the array to the rack's front right and left poles.
