3. If the primary and the secondary servers cannot be reached, the Mediatrix 4100 tries two default
servers: 192.168.0.10 and then 192.168.0.2.
If, for some reason, it is impossible to rescue the unit by using the primary and secondary servers,
setting up a server at one of these addresses within the correct subnet will provide an ultimate way
to rescue the unit. However, if these addresses cannot be reached from the unit’s subnet, the
default gateway must provide appropriate routing to them.
4. If the software download also fails with the two default servers, the Mediatrix 4100 idles for one
minute.
5. After this one minute, the Mediatrix 4100 tries to initiate the software download again.
6. If the software download fails again with the primary, secondary, and default software servers, the
Mediatrix 4100 idles for two minutes before attempting to initiate the software download.
7. If the emergency software download still fails, the Mediatrix 4100 tries to initiate the software
download again by doubling the delay between each attempt up to a maximum of 16 minutes:
• first attempt: 1 minute delay
• second attempt: 2 minutes delay
• third attempt: 4 minutes delay
• fourth attempt: 8 minutes delay
• fifth attempt: 16 minutes delay
• sixth attempt: 16 minutes delay
•etc.
This procedure continues until the software download completes successfully. The software
download can fail if the software server cannot be reached or if the software directory is not found
on the software server.
