Turn-up Sequence
The AT-iMG646MOD intelligent Multiservice Gateways are shipped with both a main software image and a
recovery software image. The recovery software image is used in the case where the main image is corrupted
during download, for example, if the power is disconnected during a software download. A default
configuration file shipped on the AT-iMG646 gateway instructs it to send a DHCP request on an untagged
VLAN and download a configuration file. The configuration file downloaded from the network server includes
information on the desired recovery software and main software load. On bootup, the gateway checks the
stored configuration, downloads the network specific configuration file, and upgrades both the recovery and
main software load. The power up and upgrade sequence is detailed in a separate turnup document. Please
contact your Allied Telesis sales representative for more information.
The gateway bootup sequence is:
1. Ensure the laptop or administrative device is powered on and connected via the management port. (Use
an RJ-45 to DB-9 adapter.)
2. Use n-8-1-38400 for the console port setting.
3. Ensure the UPS device has the battery connected so that the battery can provide power if necessary. The
battery must be plugged in and charged.
4. Turn on the power supply.
5. Observe the messages during startup
6. If necessary, the recovery software image is upgraded and the iMG will reboot.
7. If necessary, the main software image is upgraded and the iMG will reboot..
8. Ensure the device has been discovered and provisioned by the AlliedView NMS (if the AlliedView NMS is
being used). The AlliedView NMS Administration Guide has a section devoted entirely to the iMG.
9. To test the battery backup, unplug the UPS. If the iMG6x6MOD continues to function normally,
reconnect the UPS. If the iMG6x6MOD loses power, replace the UPS and return to step 3.

Troubleshooting
This chapter contains information on how to troubleshoot the gateway in the event that a problem occurs.
Problem: Gateway is not operating correctly.
Solution: Reset the unit by disconnecting and then reconnecting the power cable.
Problem: The PWR LED is off.
Solution: Check the power cable to verify that it is not damaged and that it is connected correctly.
Problem: The SYST LED is on.
Solution: Unplug the power cable and plug it in again after 20 seconds. If the LED does not turn off, unplug
the power cable and contact Allied Telesis.
Problem: The WAN LED is off.
Solution: Check the following:
Verify that the fiber optic port and FX/EPON fiber connector on the pigtail from the splice tray are clean.
Refer to Appendix B, “Cleaning Fiber Optic Connectors” on page 39 for information.
Verify that the connector is properly seated in the fiber optic port.
Verify that the fiber optic cable has an active light source.
Problem: The WAN (EPON connection) LED stays at red flashing (does not go to green).
Solution: Check the following:
Verify that the fiber optic port and FX/EPON fiber connector on the pigtail from the splice tray are clean.
Refer to Appendix B, “Cleaning Fiber Optic Connectors” on page 39 for information.
Verify that the iMAP is trying to configure the ONU. (Verify that the ONU with the corresponding MAC
has been configured on the EPON port on the iMAP.)

Cleaning Fiber Optic Connectors
The fiber optic connector consists of a fiber optic plug and its adapter. The end
of the fiber optic cable is held in the core of the ferrule in the plug. Light signals
are transmitted through the core of the fiber. Even minor smudges or dirt on the
end face of the fiber, completely invisible to the naked eye, can disrupt light
transmission and lead to failure of the component or of the entire system.
Therefore, it is of utmost importance to clean all fiber optic connectors before
use.
Figure 28 shows the ferrule in an SC connector.

Note
Rub the ferrule tip on the cleaning surface in one direction only.
10. When you reach the end of the cleaning surface, pick up the ferrule tip,
rotate and place it at the top and rub downwards at least 2 times.
Failing to pick up the ferrule tip when you reach the bottom of the
cleaning surface can result in static electricity that can damage the fiber
optic cable.
11. If desired, repeat steps 3 and 4.
12. If a fiber inspection scope is available, use the scope to inspect the ferrule
end face to make sure that it is clean.
13. Reconnect the cable to the port or protect the ferrule tip with a dust cap.
Always keep a dust cap on a fiber optic cable when it is not in use.
Do not touch the end face of the ferrule in the connector.
Warning: Do not stare into the laser beam.

Note
Using a Swab
Specially treated swabs (stick cleaners) are available for cleaning inside connector
adapters or hard-to-reach ferrule tips. These swabs, often referred to as “lint
free” or “alcohol free” swabs, are available from many vendors, as shown in
Figure 32. Stick cleaners are available in both 2.5 mm and 1.25 mm sizes for use
on SC and MU connectors respectively.
NEVER use a household cotton swab and/or alcohol to clean a fiber optic
connector. This may leave a residue on the ferrule tip.
