2. Installation

2.1 Before Connecting to the Network

Before connecting the ES-7205/ES-7208 to the

network, please pay attention to the following

instructions:

Do not put anything on top of the Switch. Place

on a hard, flat surface.

Power sockets and equipment should be within 5

feet of the Switch.

Check power supply to confirm a safe and secure

connection.

Make sure there is adequate space for proper

heat dissipation and adequate ventilation around

the Switch.

2.2 Connecting to End Nodes

Use a standard Ethernet cable to connect the Switch to

end nodes as described below. Switch ports will

automatically adjust to the characteristics (MDI-II/MDI-X,

speed, duplex) of the device to which it is connected
