Determining rack locations
The appliance and the storage shelves are both two rack units (2RU) high. To help
you identify RU spacing, many rack manufacturers typically use a system of lines
and sequential numbers starting at the bottom of the rack. The front and the rear
of the rack are marked the same to ensure that the rails are installed straight and
level. One RU has three holes. The holes for one RU are typically marked with a
line below the bottom hole and another line above the top hole.
Next, use the rack templates that ship with the storage shelves to determine the
mounting locations.
See “Best practices for rack installation” on page 23.
To determine rack locations for the storage shelves
1
A storage shelf is 2RU high. Multiply the number 2 by the number of shelves
that you plan to install.
An appliance and six storage shelves require a total of 14 RUs.
2
Use the rack templates that are provided with the hardware to determine RU
locations. The templates show the front and rear of a storage shelf in a rack.
