W1. INTRODUCTION
Q7TEH1026G 24+2G Fast Ethernet Switch is specially designed for users who want to have a smooth transition from 100Mbps
to 1000Mbps LAN. It provides 24 10/100Mbps auto-negotiation RJ45 ports, 2 10/100/1000Mbps auto-negotiation Gigabit RJ45
ports and 2 Gigabit SFP fiber ports. All RJ45 ports support auto MDI/MDIX and can be used as both common ports and uplink
ports to connect to backbone networks. With the device, users can keep their original 100Mbps network cabling distribution
system and solve the network data transmission problem via Gigabit connection. Meanwhile Q7TEH1026G can be used as an
access device for departments to connect to its company’s Gigabit backbone network via Gigabit ports. It is the ideal solution for
internet bars, schools and enterprises to directly upgrade to Gigabit network.

W2. INSTALLATION
W2.1 INSTALLATION INSTRUCTIONS
In order to keep the switch in the best working condition and prolong its life time, please refer to the following when installing it:
1. Please keep the switch in a dry and well ventilated environment to avoid possible poor stability due to excessive dust and humidity.
2. Keep the device in a safe and stable place to avoid any possible damage from falling.
3. Make sure there’s over 10cm space around the switch for proper heat dissipation.
4. Don’t put heavy articles on the Switch.
5. Make sure there is over 1.5cm vertical distance between the devices that overlap each other.
6. Please make sure the operating power accords with the switch’s rated input standard
W2.2 INSTALLATION METHODS
There are two ways to physically install the switch: set the switch on an operation desk and mount the switch in a standard-sized,
19-inch rack.
1. Install the switch to the desktop.
Correctly attach the 4 included foot pads to switch’s bottom and place it stably on the operation desk.
2. Install the switch to the standard 19-inch rack.
• Make sure the rack is stable.
• Attach the included mounting brackets to both sides of the switch with the matched screws.
• Maneuver the bracket to make sure that the slots aim at and line up with screw holes, then insert the 4 screws to fix the switch.
