Contemporary Research EISK8-100T Series Manuale Utente

Voltage in the range of 10–36 VDC or 8–24 VAC must deliver current commensurate
with power consumption.  Recommended size for solid power conductors is 16–22 AWG; 
for stranded conductors, use 16–18 AWG.  Common is directly connected to zero volts 
and chassis is isolated from zero volts.  Input connections are reverse-polarity protected. 

The “PWR” LED glows solid green when the switch is properly powered.  To aid in
troubleshooting, each copper port has two LEDs.  The Port 1 LED labelled “L” glows 
solid if a link exists, flashes to show activity and shows data rate by colour: green for 
100 Mbps and yellow for 10 Mbps.  The LED labelled “D” glows solid green if full-duplex 
is on or is unlit when the port is in half-duplex mode — but in half-duplex operation it 
will flash if a collision occurs.  The LEDs of Ports 2–6 are unlabeled but work the same. 
The fibre port (7 and 8) LEDs glow solid green if linked to a working 100BASE-FX port 
and each LED flashes when data moves through the port. 

The switch employs Auto-MDIX 
technology so that either 
straight-through or crossover 
cables can be used to connect to 
network interface adapters or to 
other hubs.  Cable issues are 
shown in the chart to the right
