2.1 Mounting the Switch on a Desk

TL-SF1024

Before placing the Switch on a desk, attach four rubber feet to the flutes on the Switch bottom, then lay the Switch on the desktop, where it is able to withstand 5kg of weight. Note: Make sure there is a grounded AC outlet within 1.5 meters, and working well; Make sure there is free space for radiating heat and airflow. Be sure not to lay anything heavy on top.

Power on

110-260V ~ 50-60Hz 0.6A
The TL-SF1016/TL-SF1024/SF-1048 16/24/48-port 10/100M Switch is powered by an AC Power Supply. Connect the Switch and power outlet by power cord. Powering on the Switch, it will be automatically initialized and the LED indicators should respond as follows: 1) All of the LED indicators will flash momentarily for one second, which represent a resetting of the system. 2) The Power LED indicator will light up.
