2. Safety
CAUTION: Product installation should be performed only by trained service personnel.
Read and follow all warning notices and instructions marked on the product or included in its
packaging, and observe all safety instructions listed in this guide while handling any ONT.
Figure 1 ONT G-25A product label
2.1 Electrical Safety
zAlways use caution when handling live electrical connections.
zDo not install electrical equipment in wet or damp conditions.
zEnsure that the power source for the system is adequately rated to assure safe operation
and provides current overload protection.
zDo not allow anything to rest on the power cable, and do not place this product where
people will stand or walk on the power cable.
zTo avoid electric shock of user which caused by over-voltage from PSTN, DO NOT connect
this unit to external PSTN.
zThis unit can only be used with the certified adaptor model 0322B1224 manufactured by LI
SHIN INTERATIONAL ENTERPRISE CORP. which comply with the requirement of limited
power source.
DANGER: Do not open the box without CIG’s permission and technical support, which is
dangerous and will void the warranty.

2.2 Laser Safety
CAUTION: Use of controls or adjustments, or performance of procedures other than those
specified herein may result in hazardous laser radiation exposure.
Invisible laser radiation may be emitted from the ends of un-terminated fiber cables or
connectors. Never look directly into an un-terminated cable or connector.
This ONT uses a class I laser device.
DANGER: Personnel handling fiber optic cables must be trained in laser safety.
CAUTION: Do not bend the fiber optic cable to a diameter smaller than 75 mm/3 inches.
Doing so may damage the fiber or prevent the signal from passing through properly.

3.8 Verify the Installation
Check LED states to verify ONT status (3.8.1).
Services are not available until the ONT is ranged and provisioned in the OLT network. If
services must be verified at the time of installation, refer to Section 3.8.2 and Section 3.8.3 for
additional instructions.
3.8.1 Verifying ONT Status
Once the ONT installation is complete, use the following procedure to verify ONT status. Figure
20 shows the typical status LED display after the ONT boot sequence is complete.

Figure 8 ONT LED status after boot sequence
• Verify that the PWR LED is lit (green) indicating that local power level is good.
• Verify that the GPON LED is not RED, indicating that the ONT is operating normally.
• Check the GPON LED status:
-If the ONT has already been provisioned in the network, the GPON LED lights green after
the ONT boot sequence and PON ranging process is complete (approximately 1 minute after
power up).
-If the ONT has not yet been provisioned in the network the GPON LED light is OFF.
Services verification cannot proceed until the GPON LED is lit green.
• Check the VID LED status:
-If video service has been enabled in the network, the VIDEO LED lights green.
-If video service has not been enabled in the network, the VIDEO LED will be off.
• Check the DATA LED status:

ONT G-25A Hardware Installation Manual
309-12201-01 Rev. A: October 2006 Cambridge Industries Group Co. Ltd 13
-If Data service has been enabled in the network, the DATA LED lights green.
-If Data service has not been enabled in the network, the DATA LED will be off.
3.8.2 Activating the ONT
The ONT is placed into service remotely through the OLT. Services to the ONT are likewise
provisioned and turned up remotely through the PON network.
• If the GPON LED is lit green, indicating that the ONT is communicating with the PON network,
no further activation is necessary and you can proceed to Section 3.8.3: Verifying Services.
• If the GPON LED is OFF, contact the NOC to activate the line. You may be required to provide
or confirm the following information about the ONT: vendor, model number, serial number. Once
the ONT has been activated in the network, and the GPON LED is lit green, you can proceed to
Section 3.8.3: Verifying Services.
3.8.3 Verifying Services
Follow local practices to connect to each active service port in the ONT to confirm service
activation.
1. Connect to each active phone jack to verify telephone numbers and services. Verify that the
OFFH LED lights green when a line is off hook.
2. If video service is included in this installation, confirm that cable TV service is operating.
Verify that the VID LED is lit green.
3. If Ethernet service is included in this installation, confirm that data is being received and
transmitted normally. On the Ethernet connector, verify that the Link LED is lit and that the
Activity LED flashes when Ethernet activity occurs.
