Installing the FTTH CPE

Connecting to the CPE
Caution: The CPE fiber line should be connected to the unit by a qualified technician
only. Do not attempt to remove the fiber cable from the CPE. If there are any
problems with the fiber cable connection, contact your service provider.
You can connect any computer with an Ethernet network interface card, a LAN
switch, hub, or other network device to the CPE’s UTP port.
Making a Connection to the UTP Port
The UTP port on the CPE supports both MDI and MDI-X operation via DIP-switch
selection. This allows you to use standard straight-through twisted-pair cables to
connect to any other network device (computers, switches, routers, or hubs).
See “Port and Cable Assignments” on page 16 for more information on connecting
straight-through or crossover UTP cables to MDI or MDI-X ports.
Caution: Do not plug a phone jack connector into any RJ-45 port. This may damage the
CPE. Instead, use only twisted-pair cable with RJ-45 connectors that conform
with FCC standards.
To connect the CPE’s UTP port directly to a computer, carry out the following steps:
1. Prepare the computer you wish to connect. Make sure you have installed a
10BASE-T or 100BASE-TX network interface card for connecting to the CPE’s
UTP port.
2. Check that the CPE’s UTP port has auto-negotiation enabled by setting the
“Auto” DIP-switch to ON. If you manually set the speed and duplex mode, be
sure that the CPE and computer’s network interface card settings match.
3. Check that the CPE’s UTP port has MDI-X enabled by setting the “MDI-X”
DIP-switch to ON. Prepare straight-through shielded or unshielded twisted-pair
cable with RJ-45 plugs at both ends (not included in the CPE package). Use
100-ohm Category 3, 4 or 5 cable for 10 Mbps Ethernet connections, or
100-ohm Category 5 cable for 100 Mbps Fast Ethernet connections.
