• There is a clearance of at least 0.8 m (2.62 ft) around the rack for heat dissipation and installation.
• There is no debris inside or around the rack.
NOTE:
The S9500E switches can be installed only in a 4-post 19-inch standard rack.
Installing slide rails and cage nuts to the rack
Besides slide rails, you can use a rack shelf to support the switch. This document describes how to install
slide rails only.
Installing slide rails
Before installing the switch to the rack, install slide rails to the rack. If the rack has slide rails, skip this
section.
NOTE:
•
Before installing the slide rails, check that the slide rails can support the weight of the switch. For the
weights of the S9500E switches, see "Appendix A Technical specifications."Slide rails or rack shelves
are not provided with the switch. Prepare them yourself, or order them from H3C.
The following uses a 19-inch rack as an example to describe the installation procedures. The height of the
front panel of the rack is a measurement of one rack unit (RU) (44.45 mm, or 1.75 in). As shown in callout
2 in Figure 19 , each 1 RU has three holes with center-to-center spacing. When installing the slide rails,
make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area between
holes.
To install the slide rails:
1. Determine the position of the slide rails on the rack.
2. Align the screw holes on the two sides of the slide rails with the corresponding holes on the rack,
and then fasten the screws.
3. Install the other slide rail in the same way. Keep the two slide rails at the same height so that the
switch can be placed evenly.
