5.9 Replacing an ODU
Prior to any action verify that both ODUs have the same software version
(Configuration > Configure site > Inventory). If one ODU has an old software
version, perform a software upgrade. It is important to configure the new ODU
exactly the same as the old ODU to avoid configuration mismatches, which will
disrupt the link.
An ODU may be replaced with a new ODU in one several ways.
• Use the backup
If a backup of the configuration is available, restore that configuration using
Configuration > Configure site > Restore.
• Manual Configuration
The new ODU can be configured manually according to the link configuration,
remember to use the same settings for SSID, channels, link password, IP
addresses, and names.
• Restore Factory Setup
From version 1.6xx the feature of Restore Factory Setup is available. Using
this feature we recommend putting the remaining ODU back to factory setup
Configuration>Configure site>Advance option, and then activate the second
ODU reconfiguring the link from scratch.
Option number 3 is our recommended option preventing configuration
mismatches.
5.10 Frequently Asked Questions
Q: What performance issues will arise due to environmental conditions?
A: Airmux-200 is not sensitive to environmental conditions. However if heavy rain
or snowfall is expected ensure the performance by allowing a higher fade margin
in the link budget planning calculations.
Q: When using the Airmux-200, what is the potential for interference between
our system and other cellular or wireless Networks devices?
A: The Airmux-200 is a robust system. However since it operates in unlicensed
band there maybe some interference. Nevertheless, the fact that we can
manually set the frequency gives us the flexibility to find a clear channel. In
addition each Airmux-200 link uses unique user configurable SSID code.
Q: What protocol does the Airmux-200 use, i.e. 802.11?
A: Airmux-200 uses a proprietary protocol; this protocol contains improved
options that more efficiently support the clock reconstruction from the TDM
services.
