5. Again, run the Configuration Wizard on the secondary link, and in the panel of
Figure 12-4

The Hot Standby will automatically revert to the primary link within 50ms.
ODU Replacement
Both the primary and secondary replacement ODUs require pre-configuration prior to inser-
tion into the link. The items to be pre-configured are
• HSS mode
• Link ID
• Frequency
• Hot Standby mode – using the new Services panel in
• IP address (optional)
Pre-configuration must be carried out before the new ODU is
connected to its IDU. If you try to do it "live" against its IDU, it will
cause spurious transmissions and a service break.
Note

To pre-configure an ODU:
1. Attach the new ODU to an IDU or a PoE device.
2. Run the RADWIN Manager and use Hot Standby tab of

Enter the required Link ID and frequency.

To replace an ODU for primary or secondary link, at either site:
• Install the pre-configured ODU. (Since the other link is working normally, nothing
need be done with it. If the secondary ODU was replaced, TDM service remains as is
on the primary link. If the primary ODU was replaced, then the TDM service will shift
back to the primary link.)
