QSW-4700 Series Switches Hardware Installation and Reference Guide
INSTALLING THE SWITCH
56
3.2. Before You Begin
Confirm the following requirements before installation:
• The installation site provides sufficient space for heat dissipation.
• The installation site meets the temperature and humidity requirements of the switch.
• The power supply and required current are available in the installation site.
• The Ethernet cables have been deployed in the installation site.
3.3. Mounting the Switch
Notes:
• Connect the power cords of different colors to the corresponding grounding posts.
• Ensure the power cords are securely connected.
• Do not place heavy objects on the switch.
• Maintain a minimum clearance of 100 mm (3.94 in.) around the device for air circulation.
• Keep the switch away from high-power radio stations, radar stations, and high-frequency
high-current devices. Use EMI shielding such as shielded interface cables to minimize
interference when necessary.
• Route interface cables only indoors to prevent signal ports from getting damaged by
overvoltage or overcurrent caused by lightning strikes.
3.3.1. Mounting the Switch in a Rack
All models of the QTECH QSW-4700 series switches can be installed in a standard 19-in. four-
post EIA rack. Mount the switch in the rack with the front panel face forward.
1. Use a Phillips-head screw driver to secure a bracket to each side of the switch with
two screws.

2. Install two cage nuts on the inside of each front rack and drive the screws halfway into
the cage nuts.
