Table 7 Description of signs on the slide rails
Sign Meaning
F/L Front end of the left slide rail
F/R Front end of the right slide rail
Mark the position on the rack for installing the slide rail. To ensure the stability of the rack, mount
2.
the switch at the lowest possible position. To mount multiple switches on the rack, mount the
heaviest switch at the bottom of the rack.
Position the chassis of the switch according to its height. For specifications, see the chapter
a.
"Appendix A Technical specifications."
Make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area
b.
between holes, as shown in Figure 5.
Each rack post requires six screws to attach the slide rail. You only need to mark the uppermost
c.
square hole and lowermost square hole for installation.
Mark the square holes at the same height on the other three rack posts.
d.
NOTE:
One rack unit 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 larger than that
between two adjacent standard installation holes.
