Power
If an NS12P or NS12PF Ethernet switch shows no power:
-
Check that the power source is functional, and ground,
neutral and live connections are properly seated
-
Check the power lead for damage
-
Check the NS12P’s or NS12PF’s fuse
If an NS6 Ethernetswitch shows no power:
-
Disconnect the NS6 Ethernet switch. Wait for 10 seconds and
apply power again
-
Check that the Ethernetswitch the device is connected to
conforms to 802.3AF and that this feature is enabled (check
PoE power availability and management software)
-
Check that the RJ45 Network cable coming from an 802.3 AF
compliant Ethernet Switch is seated in the port marked as
PoE Input
-
Check that this cable is properly wired (all pins connected, in
the proper order) and undamaged
-
Use a different cable
-
Connect the NS6 Ethernet switch to a different port or a dif
ferent switch
-
If no LED’s are lit contact your local XLNT service point
Data
If an NS6, NS12P or NS12PF Ethernet switch is powered, but ap-
pears not to transmit or receive data:
-
Check that the Link LED of the connected port is lit. If not,
check that the cable has no shorts or broken wires, or that
the connected Ethernet device’s power source is functional,
and ground, neutral and live connections are properly
seated. Also check that this device is operational. Try
replacing the Ethernet cable, or see if another device does
communicate on the same port
-
Check that the Link LED is blinking. If not, no communication
is available. Check that the connected Ethernet device is
operational and is sending data across Ethernet
