A chassis assembly using the Chassis Accessory Kit can be installed either from the
front or from the back of the rack. A chassis assembly using the CRM kit can be
installed only from the front of the rack.
Begin installing your chassis assemblies at the bottom of the rack or cabinet. This
provides support for each chassis before it is securely mounted, and greatly simplifies
getting the chassis square and level in the rack.
Standard Chassis Mounting Hardware
To install a chassis using the standard Chassis Accessory Kit, do the following:
1. When installing into a cabinet enclosure, loosely attach the back adjustable
mounting brackets to the chassis with 5 screws on each side.
2. Position the chassis in the cabinet so that the front of the chassis lines up with the
front rail and then slide the adjustable back brackets into place. Tighten the
screws that hold the back brackets in place.
3. With the back brackets firmly attached to the chassis, slide the chassis into the
cabinet from the back. Open the front bezel of the chassis and then attach the
front brackets with three screws on each side that pass from the inside of the
chassis to tapped holes in the brackets on the outside.
NOTE: For your convenience, the front brackets can be attached from either the
inside or the outside of the chassis.
4. Using the hardware provided with your cabinet, attach the chassis mounting
brackets to the cabinet rails.
CAUTION: To avoid equipment damage and potential personal injury,
never install the chassis with only the front bracket as an attachment.
5. If you are installing a chassis into a two-post rack with only a central mounting
point, use the front brackets attached at the center of gravity of the chassis. The
center of gravity is 14.7 inches (37 cm) back from the front faceplate. A set of rack
ear mounting holes is provided at this location (the third group of 3 holes back).
This point should line up with the rack sidebars to assure maximum stability of the
rack. Figure 14 shows a two-post open rack with one chassis installed, properly
centered in the rack.
NOTE: The CRM kit cannot be used in a two-post rack.
