Mediatrix 4104
Emergency Firmware Procedure
If the firmware download is suddenly interrupted, it may not be complete. Without any protection against this
situation, the Mediatrix 4104 is not functional.
A transfer may be interrupted for the following reasons:
An electrical shortage.
The user of the Mediatrix 4104 can accidentally power off the unit.
Depending on the moment when the firmware download has been interrupted, the emergency firmware
procedure (also called rescue application) can automatically start a new firmware download to repair the
firmware if it has been corrupted by the interruption. However, there is a small but critical time frame during
which unrecoverable errors could happen. This is why it is very important that the unit is not turned off during
firmware downloads.
Using the Emergency Firmware
When the emergency firmware procedure starts, the following steps apply:
1.
The Mediatrix 4104 tries to initiate the firmware download with the primary firmware server.
2.
If the firmware download fails with the primary firmware server, the Mediatrix 4104 tries to initiate
the firmware download with the secondary firmware server.
3.
If the primary and the secondary servers cannot be reached, the Mediatrix 4104 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 firmware download also fails with the two default servers, the Mediatrix 4104 idles for one
minute.
5.
After this one minute, the Mediatrix 4104 tries to initiate the firmware download again.
6.
If the firmware download fails again with the primary, secondary, and default firmware servers, the
Mediatrix 4104 idles for two minutes before attempting to initiate the firmware download.
7.
If the emergency firmware download still fails, the Mediatrix 4104 tries to initiate the firmware
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 firmware download completes successfully. The firmware
download can fail if the firmware server cannot be reached or if the firmware directory is not found
on the firmware server.
