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.
Make sure the clearance above the slide rail is sufficient for the switch and the slide rails can support the weight of the switch. For the dimensions and weight of the 12500E switch, and the weight of the hardware components, see "Appendix A Technical specifications."
