Removing The Rack Doors; Marking The Rack - Dell 8 Installation Manual

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.
1 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).
