(24.80 in) to 900 mm (35.43 in).
The bottom-support rails are applicable only to four-post racks. To attach the bottom-support rails to
a rack, make sure the rack depth is in the length range of the bottom-support rails.
2 Installation procedures
WARNING!
To avoid bodily injury, keep the bottom-support rail horizontal and hold the front and rear endsof the
bottom-support rail when you unpack and install a bottom-support rail.
The bottom-support rail installation might vary by rack type. The following installation procedure is for
your reference only.
To install the bottom-support rails:
1. Read the signs on the bottom-support rails to avoid making a mistake.

2. Mark the bottom-support rail installation position on the mounting rails:
The bottom-support rails are installed in the 1 RU region below the device.
a. As shown in Figure 2, align the installation holes in the bottom-support rail with the
uppermost and lowermost standard square holes in the 1 RU region on the mounting rail.
The bottom-support rail has a locating tab on the front and rear ends. You can also align the
locating tab with the auxiliary installation hole in the 1 RU region on the mounting rail.
Figure 2 uses the right bottom-support rail and the right front mounting rail.

4. Attach the bottom-support rails to the rack:
a. Place the right bottom-support rail at the marked position in the rack. Hold both ends of the
right bottom-support rail to compress it so that the locating tabs at both ends of the
bottom-support rail are inserted into the auxiliary installation holes in the mounting rails.
b. Use screws to secure the bottom-support rail to the mounting rails.
c. Perform the same steps to install the left bottom-support rail. Make sure the two
bottom-support rails are at the same height so the device can be placed horizontally.
