LEDs to indicate operating status are on the front side.  There are power (PWR) 
and bridge-inside (BR) indicators for the unit.  There are collision (COL)  indicators for each 
of the 10Mb and 100Mb domains, 
for visual indication of the 
operating status of each domain.    
And  there are link (LK/RX),

100M/Auto  indicators for each port.  (See Section 1.1 “Specifications” for a technical 
description of the LEDs). The unit has a cooling fan on the side which sends warm air out 
away from the unit to the side.   Stacking cables connect in the rear, except for the DS8016-R 
model. (see Section 2.3 for stacking information). 
                   The AC power cord connector,  a universal recessed-male IEC type, is in the left 
rear of the chassis. The internal AC power supply is auto-ranging for any AC power input of 
115 - 230 vac, 50 - 60 Hz. (An internal DC power supply is optional, see Appendix A). 
 
2.2.2 
10 / 100 Speed Auto-sensing  
All sixteen RJ-45 twisted pair ports support auto-sensing for speed, independent of 
the other ports.  Speed-sensing is performed by the DS8016’s electronics in accordance with 
the standards of the IEEE 802.3u auto-negotiation standard.  If the connected device or node 
indicates that it is capable of 100Mb speed, then operation on that port will be at 100Mb/s.  If  
the connected device does not positively indicate that it is capable of 100Mb speed, then the 
operation on that DS8016 port will be at 10Mbps.  Of course, the hubs’ auto-negotiation 
technique is only for 10 / 100 speed, and does not provide for any full-duplex operation. 
When a port is connected and LINK is present, the speed on that port that has been 
sensed by the DS8016 hub will be indicated by the ‘100M/Auto’ LED for that port. The 
‘100’ LED is ON when 100Mb speed is sensed, and is OFF when 10Mb speed is in use.  
When a port is not connected, the ‘100M/Auto’ LED corresponding to that port will be 
blinking to indicate that it is trying to auto-negotiate. (See section  4.3 for operation of the 
LED’s).
