Turn-Up and Troubleshooting
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.
