Connect an Ethernet cable into any switch port and connect the other side to your
attached device. The Link/Act LED (green or yellow) will light up when the cable is correctly
connected. Refer to the
LED Indicator
section for descriptions of each LED indicator.
If a port LED is off, go back and check for connectivity problems between that port and the network
device connected.
The maximum cable length for 10/100/1000BaseT with Cat 5 twisted pair cables is typically 100m
(328 ft.).
*PD Port Wiring
Port 1 to 4 provides PoE injection function with maximum 35W/each ability to power up the
powered device using the straight-through or cross-over Ethernet cable.
The PoE switch follows the IEEE802.3af Alternative A and/or B mode connector assignment. The
following table shows pin assignment of alternative A and/or B for the Power Source Equipment.

Be sure the twisted pair cable is bound with the standard RJ-45 pin. If the RJ-45 is bound with the
wrong pin number, the PoE switch will not recognize the PD and won’t deliver DC power to the PD.
The yellow PoE LED will light up when the cable is correctly connected. Refer to the
LED
Indicator
section for descriptions of each LED indicator. If a port LED is off, go back and check
for connectivity problems between that port and the network device connected.
