Note:
The mounting brackets are used for fixing rather than weight bearing. In a 19-inch
standard rack, the weight of the switch is supported by the shelf beneath it.

3.1.2 Mounting the Switch on a Tabletop/Workbench

When placing the switch on a tabletop or workbench, you simply need to:
Make sure that the tabletop or workbench is clean, flat, and sturdy.
Allow 10 cm (3.9 in.) of clearance around the sides of the chassis.
Do not place heavy objects on the switch.

3.2 Connecting the Power Cord and the Ground Wire

3.2.1 Connecting the AC-Input Power Cord

I. AC-input power socket (recommended)
You are recommended to use a monophase three-line power socket with a ground
contact or a general purpose PC power socket, making sure that the power point is well
connected to building ground. Normally, the ground point of the power source in a
building was buried in the ground during the construction and wiring. Still, you must
make sure of that.

II. Connecting the AC-input power cord
Step 1: Connect one end of the chassis ground wire to the grounding screw on the rear
of the chassis and the other end to the ground as near as possible.
Step 2: Connect one end of the power cord to the power socket on the rear of the
chassis, and plug the other end to the AC power jack of the power source.
Step 3: Check that the PWR LED on the front panel of the switch is ON.
