The  Cable  Diagnostic  function  operates  only  during  the  Switch  boot  up  (when  the  Switch  is  first 
powered on). 
The  Cable  Diagnostic  first  scans  the eight Ethernet  ports  to  determine  if  the  Ethernet  cable  is  in 
good  working  order.  This  process  is  indicated  by  the Speed LED  blinking  green  for  each  of  the 
eight ports, sequentially. The initial port scan takes about 10 seconds. If a cable fault is detected, it...

Mounting the Switch on a Wall 
The  DGS-108  can  be  mounted  on  a  wall. Two  mounting  slots  are  provided  on the  bottom  of  the  Switch  for  this 
purpose. Make sure that the front panel is exposed in order to view the LEDs. Refer to the illustration below: 
A.)  Cement wall  
1. Mount the nylon screw anchors into a cement wall. 
2. Drive the T3 x 15L screws into the nylon screw anchors. 
3. Hook  the  mounting  holes  at  the  back  of  the...

Switch To End Node 
End  nodes  include  PCs  outfitted  with  a  10,  100,  or  1000  Mbps  RJ-45  Ethernet/Fast  Ethernet  Network  Interface 
Card (NIC) and most routers. 
An  end node  can  be  connected  to  the  Switch  via  a  twisted-pair  Category  3,  4,  5,  or  5e  UTP/STP  cable. The  end 
node can be connected to any of the ports...
