Installing The Switch In A Rack - H3C S12508-AC Installation Manual

Installing the switch in a rack

Installation preparation
Confirm the following preparations before starting installation:
The rack is sturdy and securely grounded.
•
• There is sufficient clearance of 0.8 m (2.62 ft) around the rack for heat dissipation and installation.
There is no debris inside or around the rack.
•
CAUTION:
When moving the switch, hold the handles at both sides of the chassis. Do not hold the plastic panel of the
chassis, the handle of the fan tray, the handle of the back cover of the chassis, or the air vents of chassis.
Any attempt to carry the switch with these parts may cause equipment damage or even bodily injury.
Installing slide rails and cage nuts to the rack
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 S12500 Routing Switch Series, see the chapter "Appendix A Technical specifications."
• Besides slide rails, you can use a rack shelf to support the switch. This document describes how to install
slide rails only.
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 between the holes of 15.87 mm
(0.63 in), 15.87 mm (0.63 in), and 12.70 mm (0.5 in). 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:
Mark the position of the slide rails on the rack.
1.
Align the screw holes on the two sides of the slide rails with the corresponding holes on the rack,
2.
and then fasten the screws.
Install the other slide rail in the same way. Keep the two slide rails at the same height so that the
3.
switch can be placed evenly.
