3.1.5 Use Front and Rear Mounting Ears
Follow these steps to install a switch into a 19-inch standard rack with front and rear
mounting ears:
1) Wear an ESD-preventive wrist strap to check the grounding and stability of the
rack.
2)
Take out the screws which are packed together with the front mounting ears, and
fix one end of mounting ears to the switch, as shown in Figure 3-4.
3) Take out the load-bearing screws (packed together with the rear mounting ears)
and place them in a proper position on the sides of the switch, as shown in Figure

Note:
There are three positions to mount a load-bearing screw on both sides of a switch. You
should select a proper position according to the actual requirements. The rear
mounting ears tightly contacted with the load-bearing screws can support the switch.
4) Select a position to install the switch and fix the rear mounting ears to the rear
brackets with screws and captive nuts, as shown in Figure 3-7.
