• To ensure stability of the rack, install the slide rails to the lowest possible position when installing a
single switch on the rack. To install multiple switches on the rack, mount the heaviest switch at the
bottom of the rack.
• Identify the rack position for the switch. For the height and other specifications of the 10500
switches, see "
Appendix A Chassis views and technical specifications ."
Slide rail installation varies with rack type. The following installation procedure is for your reference only.
To install a slide rail:
1. Read the signs on the slide rail (see Table 5 ) to avoid making a mistake.

Table 5 Description of signs on the slide rails
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 position on the rack for installing the slide rail:
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 for installation.
c. Mark the square holes at the same height on the other three rack posts.
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
wider than that between two adjacent standard installation holes.
