Mediatrix 4100
ss: Seconds.
The image software download is initiated at the first occurrence of this value and thereafter with a
period defined by imageAutoUpdatePeriod. Let's say for instance the automatic update is set with
the time of day at 14h00 and the update period at every 2 days.
• If the automatic update is enabled before 14h00, the first update will take place the
same day at 14h00, then the second update two days later at the same hour, and so
on.
• If the time range is set to '14:00 - 15:00' and the automatic update is enabled within
those hours, the first update will take place the following day. This means that a range
of '00:00:00 - 23:59:59' will always take place the next day.
9. Set the imageAutoUpdateEnable variable to enable.
If one of the telephones/faxes is off-hook, the Mediatrix 4100 will perform the download five minutes
after both ports are detected on-hook.
Software Downgrade
It is possible to downgrade a Mediatrix 4100 from the current version (for instance, v5.0rx.x) to an older version
(for instance, v4.4rx.x).
 To perform a software downgrade:
1. Create, in a common folder under the TFTP root path, the current (for instance, v5.0) and older (for
instance, v4.4) applications folders.
2. Re-update the Mediatrix 4100 with the current application.
The Mediatrix 4100 runs the current software version (v5.0rx.x).
3. Perform the software downgrade to the older application (v4.4rx.x) as described in “
Download
Procedure” on page 118.
Emergency Software Procedure
If the software download is suddenly interrupted, it may not be complete. Without any protection against this
situation, the Mediatrix 4100 is not functional.
A transfer may be interrupted for the following reasons:
 An electrical shortage.
 The user of the Mediatrix 4100 can accidentally power off the unit.
Depending on the moment when the software download has been interrupted, the emergency software
procedure (also called rescue application) can automatically start a new software download to repair the
software 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
software downloads.
Using the Emergency Software
When the emergency software procedure starts, the following steps apply:
1. The Mediatrix 4100 tries to initiate the software download with the primary software server.
2. If the software download fails with the primary software server, the Mediatrix 4100 tries to initiate
the software download with the secondary software server.
Note: If you perform a default reset on the Mediatrix 4100, you must download the current version into the
unit before performing the software downgrade procedure.
