Installing the switch in a 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.
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.
•
• The total height of the switches to be installed is no higher than the height of the rack and enough
clearance is reserved for cable routing.
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.
To ensure correct installation, use industry-standard slide rails or rack shelves. Slide rails or rack shelves
are not provided with the switch. Prepare them yourself, or order them from HP.
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.
Before installing the slide rails, verify that the slide rails can support the weight of the switch. For the
weight of the 12500 switch and hardware components, see "Appendix A Technical specifications."
