Step5 Place the switch on the tray horizontally, slide the tray into the cabinet, and fix the other end of mounting brackets to the front brackets with crews and captive nuts, as shown in Figure 3-4.

Mounting the Switch on a Workbench

In many cases, standard 19-inch racks are not available. Therefore, switches are often placed on clean workbenches. To place your switch on a workbench, you simply need to:

Make sure that the workbench is clean, flat, and sturdy.

Make sure that the environment is well ventilated and allows 10 cm (3.94 in.) of space around the chassis for heat dissipation.

Do not place heavy objects on your switch.

The vertical distance between two switches must be at least 1.5 cm (0.59 in).

Connecting the Grounding Cable

Correctly connecting the chassis grounding cable is crucial to the lightning protection and electromagnetic susceptibility (EMS) of a switch.

The power and grounding terminals in this section are for illustration only.

The power input end of the switch is connected with a noise filter, whose central ground is directly connected to the chassis, forming the so-called chassis ground (commonly known as PGND). This chassis ground must be securely connected to the earth so that the faradism and leakage electricity can be safely released to the earth, enhancing the EMS capability of the switch.

When a Grounding Strip is Available

When a grounding strip is available at the installation site, attach one end of the yellow-green grounding cable (PGND cable) of the switch to the grounding screw on the grounding strip (the grounding screw and the grounding hole are on the rear panel of the switch and are marked with a grounding sign). To do this, follow these steps:

Step1 Remove the grounding screw from the rear panel of the switch chassis.

Step2 Put the supplied OT terminal of the PGND cable on the grounding screw.

Step3 Fasten the grounding screw, which is attached with the OT terminal of the PGND cable, into the grounding screw hole with a screwdriver.
