Sign Meaning Remarks
F/L Front end of the left slide rail Mount this end to the front left rack post.
F/R Front end of the right slide rail Mount this end to the front right rack post.
2. Mark the cage nut installation positions on the rack posts for installing the slide rail.
The square holes on the rack post are divided into rack units (RUs). One RU has three holes, the
middle of which is an auxiliary installation hole, and the other two are standard installation holes.
You can distinguish them by the space between each two holes. The space between a standard
installation hole and an auxiliary installation hole is wider than the space between two adjacent
standard installation holes.
a. Make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area
between holes, as shown in
Figure 4 .
b. Each rack post requires six screws to attach the slide rail. You only need to mark the uppermost
square hole and lowermost square hole on the rack post.
c. Mark the square holes at the same height on the other three rack posts.
