Installing an R100 chassis

About this section

This section describes your options for installing an R100 chassis in a freestanding 19-inch equipment rack.

Positioning your chassis

The R100 chassis has adjustable installation brackets that enable you to install it in one of three horizontal positions in the rack.

WARNING
When you install disk shelves and a chassis into a rack, you must install the equipment from the bottom up to ensure the greatest stability.

Front-installed position--The installation brackets lie flush with the chassis front panel.
The chassis is shipped with the installation brackets in this position. The following figure shows a front-installed R100 chassis.

Two mid-installed positions--You can move the installation brackets to extend the chassis 4.75 inches or 9.5 inches in front of the rack, providing more room to service the chassis from the back.
The following illustration shows an R100 chassis mid-installed (4.75 inches) in a rack.

WARNING
To avoid injuring yourself or damaging the chassis, you must work with at least one other person when you install the chassis in the rack.

Moving the installation brackets

If you want to mid-install the chassis in a rack, you must move the installation brackets on the sides of the chassis from the default position.

To move the installation brackets, complete the following steps.

Step	Action
1	Put on an antistatic wrist strap and attach the grounding leash so that you are appropriately grounded.
2	Use a #2 Phillips screwdriver to remove the installation brackets attached to each side of the chassis.
3	For each installation bracket, select a position 4.75 inches or 9.5 inches from the first hole on one side of the chassis and align the installation bracket holes with the chassis holes.
4	Attach each installation bracket to the chassis by inserting screws into the bracket and chassis holes and tightening the screws.

Installing the chassis

To install the chassis in a 19-inch equipment rack, complete the following steps.

Step	Action
1	Put on an antistatic wrist strap and grounding leash.
2	Select four holes on each front rack rail. These holes should have the same spacing as the holes on the chassis installation brackets.
3	Align the rack holes with the installation bracket holes on the chassis. The person assisting you should stand behind the rack to help support the weight of the chassis.
4	Insert the mounting screws in the bottom hole on each side first and tighten the screws using a #2 Phillips screwdriver. Note The rack can support the weight of the chassis after the chassis is attached by the bottom screws. You do not need another person to hold the chassis from the back of the rack after fastening these screws.
5	Insert and tighten the remaining screws.
