Installation Guidelines
This section will discuss the hardware installation guidelines that the user must follow in order to properly and safely install this switch into the appropriate environment.
Visually inspect the power cord and see that it is fully secured to both the power connector, on the Switch, and the electrical outlet that supplies power.
Install the Switch in a fairly cool and dry place within the acceptable operating temperature and humidity ranges.
Install the Switch in a site free from strong electromagnetic field generators such as motors, vibration, dust, and direct exposure to sunlight.
Installing the Switch without a Rack
This section is used to guide the user through installing the Switch in an area other than a switch rack. Attach the included rubber feet to the bottom of the Switch. Take note that there should be marked blocks on the bottom of the Switch to indicate where to attach the rubber feet. These markings are usually found in each corner on the bottom of the device. The rubber feet cushion the Switch, protecting the casing from scratches and preventing it from scratching other surfaces.

Install the Switch on a sturdy, level surface that can support the weight of the Switch. Do not place any heavy objects on the Switch. The power outlet should be within 1.82 meters (6 feet) of the Switch. Make sure that there is proper heat dissipation from and adequate ventilation around the Switch. Leave at least 10 cm (4 inches) of space at the front, sides, and rear of the Switch for ventilation.
Installing the Switch in a Standard 19'' Rack
This section is used to guide the user through installing the Switch into a switch rack. The Switch can be mounted in a standard 19"(1U) rack using the provided mounting brackets. Fasten the mounting brackets to the sides of the Switch using the screws provided.

Installing Transceivers into the Transceiver Ports
The Switch is equipped with Enhanced Small Form-factor Pluggable (SFP+) ports that can be used to connect various other networking devices to this switch that do not support the standard RJ-45 wiring connection. These ports are generally used to connect this switch to optical fiber connections and can be used to connect devices to the Switch over great distances. The maximum distance that the RJ-45 wiring connection can reach is 100 meters. Fiber optic connections can span several kilometers.

Power On (AC Power)
Plug one end of the AC power cord into the power socket of the Switch and the other end into the local power source outlet.
Power Failure (AC Power)
In the event of a power failure, just as a precaution, unplug the power cord from the Switch. After the power returns, plug the power cord back into the power socket of the Switch.
Installing Power Cord Retainer
To prevent accidental removal of the AC power cord, it is recommended to install the power cord retainer together with the power cord.
With the rough side facing down, insert the tie wrap into the hole below the power socket.
