Rack Installation Guide 11

Removing the Rack Doors

See the procedures for removing doors in the documentation provided

with your rack cabinet.

CAUTION: Because of the size and weight of the rack cabinet doors,

never attempt to remove or install them by yourself.

CAUTION: Store the two doors where they will not injure someone if the doors

accidently fall over.

Marking the Rack

You must allow 10 U (44.45 cm or 17.5 inches) of vertical space for each system

you install in the rack (see Figure 1-3).

NOTE: Your rack may already be marked and not require this procedure.

CAUTION: If you are installing more than one system, install the rail assemblies

so that the first system is installed in the lowest available position in the rack.

Place a mark on the rack’s front vertical rails where you want to locate

the bottom of the system you are installing in the rack cabinet.

The bottom of each 1-U space is at the middle of the narrowest metal

area between holes (marked with a horizontal line on some rack cabinets,

see Figure 1-3).
