switch onto a piece of DIN rail or use the 
included panel mount brackets for wall or 
panel mounting 
2.
Connect power to the switch 
 
24 or 48 VDC
If redundancy is desired be sure to 
connect two separate power supplies by 
using the two DC inputs on the terminal 
blocks 
If only one power input is used the Fault 
LED will light (this is normal) 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
RJ-45 ports: The RJ-45 ports auto-sense for 10 or 100 Mbps 
device connections. The auto MDI/MDIX feature allows 
connections to switches, workstation and other equipment 
without changing straight through or crossover cabling. The 
charts below show the cable pin assignments for straight 
through and crossover cables. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
PoE ports: The PoE ports on this switch follow Alternative A 
standards and are limited to 15.4 Watts of power output per 
port. Ports 1 thru 4 support the IEEE802.3af standard and 
are classified as (PSE) power sourcing equipment, which 
means they can be used to power (PD) powered devices.
