Ethernet/optic fiber connections
AN-TDM-IP-1E1/2E1-A provides four 100Base-Tx Ethernet electrical
interfaces (two ports are uplink ports used to connect with transmission network and
the other two are local data ports used to connect with local Ethernet), and one
100Base-Fx optical interface used as either uplink port or local Ethernet port such as
switch.
Ethernet Optical adopts SFP integrated optical modules, and the port labeled
（
is for optical signal output,
（
for input. Also Ethernet optical port can use
single-fiber optical module which has only one optical interface. The wavelength of
single-fiber optical module means its luminescence wavelength, 1310nm or 1550nm.
It should note that equipments with the same luminescence wavelength cannot
connect with each other. So it should select the equipments with the match
luminescence wavelength when using the single-fiber module.
Note:
1.
At auto-negotiation mode, Ethernet electrical port supports HP auto-MDIX
function and it can check the transmission and receiving sequence and make
configuration. So both MDI and MDI-X interfaces are supported and both
cross line and direct line can be selected.
2.
Network Management can be used for all the Ethernet ports except Data1
port. But to ensure VLAN setting not affecting monitoring, it’s better to use
the Ethernet electrical port labeled “Data2/NM” as the network
management monitoring interface.

Troubleshooting
After
power
up
of
equipment
AN-TDM-IP-1E1/2E1-A the system
should start after 90seconds to work properly. The system completion startup SYS
light change from long bright to flashing light. You can observe each interface light to
judge each port working statue.
