7.10.11 iMG/RG Recovery
This procedure is used when the iMG/RG has gone into Recovery Mode. This could happen, for example, if during the middle
of an upgrade procedure the iMG/RG lost power and as a result went into Recovery mode.
Note: The iMG/RG will have a constant red light on when it has entered Recovery mode.
There are two procedures that can be used, depending on whether the existing RG is to be recovered or a new iMG.RG is to be
swapped.
7.10.11.1 Recover Existing iMG/RG
1. Add the Bootstrap VLAN to the subscriber’s iMAP port.
2. The iMG/RG should be able to contact a DHCP server and get an IP address
3. Using a tool called the Windows Loader, input the iMG/RG IP Address and the telnet password, default value “friend”.
Note: For information on the Windows Loader, refer to the Software Reference Manual for the AT-RG600. This
document can be found on the Allied Telesis web site.
4. The RG should then reboot and go back to Normal mode, with the bootstrap loading on the RG-mgmt VLAN.
5. Using the AlliedView NMS application (Device Backup/Restore), restore the last saved configuration file for the RG.
6. The bootstrap VLAN can now be removed from the subscriber’s port.
7.10.12 Recover using new Hardware
Use this procedure to replace suspected bad iMG hardware unit.
7.10.12.1 Prerequisites
• Ensure iMG hardware model of new unit matches model of unit to be replaced (old unit).
• Ensure the new iMG unit has not been previously managed by the target NMS, to prevent possible complications.
• Ensure iMG software boot load release matches release of iMG to be replaced.
• Ensure the new iMG unit contains only the “factory” system configuration file.
• Ensure the old iMG configuration has been backed up recently. If a current backup is not available, do not use the proce-
dure in 7.10.12.2. Instead, do the following:
1. Record all subscriber configuration information
2. Deprovision the subscriber (refer to 7.10.9).
3. Provision using a new iMG hardware unit, and the recorded information (refer to 7.6).
7.10.12.2 Procedure
1. Add the Bootstrap VLAN to the subscriber’s iMAP port.
2. Swap the existing iMG/RG with a new one.
1. Power off the old iMG unit, and replace with new unit, connecting all cables.
2. Power on the new unit.
3. The iMG/RG should be able to contact a DHCP server and get an IP address and go through the bootstrap process.
4. The AlliedView NMS should discover the new iMG/RG and restore the last saved config file automatically.
5. The AlliedView NMS should then remove the bootstrap VLAN automatically.
6. Verify iMG management and all provisioned services.
