Note: The figure is to illustrate the application and principle. The power plug you get 
from the package and the  socket in your  situation  will  comply with  the regulation in 
your country, so they may differ from the figure above.
For TL-SG1048/TL-SG1024/TL-SG1024D/TL-SG1016/TL-SG1016D/TL-SG1008:
 
After the device is powered on, it begins the Power-On Self-Test. A series of tests run 
automatically to ensure the device functions properly. During this time, its LED indica-
tors will respond as follows:
All of the LED indicators will flash momentarily for one second, which represents a 
 
resetting of the system. 
The Power LED indicator will light up.
 
For TL-SG1008PE:
The LED indicators for TL-SG1008PE are classified into two parts: 
the LEDs indicating switch  status including  Power LED, Link/Act LEDs and  1000Mbps 
LEDs; the LEDs indicating PSE status, including PoE MAX LED and PoE Status LEDs.
After the device is powered on, it begins the Power-On Self-Test. A series of tests run 
automatically to ensure the device functions properly. During this time, its LED indica-
tors will respond as follows:
All of the LEDs indicating swith status will flash momentarily for one second, which 
 
represents  a  resetting  of  the  switch system.  The PoE MAX LED  will keep  on  for 
approximately ten seconds, representing a resetting of the PSE system. Take note 
that the PoE Status LEDs won't light up during this period.
The Power LED indicator will light up.
