7. Set the waiting period between each software update in the imageAutoUpdatePeriod variable.
The time unit for the period is specified by the imageAutoUpdateTimeUnit variable (see Step 6).
Available values are from 1 to 48.
8. If you have selected days in Step 6, set the time of the day when to initiate a software update in the
imageAutoUpdateTimeRange variable.
The time of the day is based on the sntpTimeZoneString variable setting (see “Chapter 20 - SNTP
Settings” on page 287 for more details).
You must have a time server SNTP that is accessible and properly configured, or the automatic
software update feature may not work properly. It is assumed that you know how to configure your
SNTP server. If not, refer to your SNTP server’s documentation. You can also refer to
“Chapter 20
- SNTP Settings” on page 287 for more details on how to configure the Mediatrix 4104 for a SNTP
server.
If a time range is specified, the unit will initiate the image software download at a random time within
the interval specified.
The format should be one of the following:
hh[:mm[:ss]]
hh[:mm[:ss]] - hh[:mm[:ss]]
Where:
hh: Hours.
mm: Minutes.
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 4104 will perform the download five minutes
after both ports are detected on-hook.
Spanning Tree Protocol (STP)
Many network switches use the Spanning Tree Protocol (STP) to manage Ethernet ports activity. When a
software download occurs, the
ETH1 and ETH2 connectors of the Mediatrix 4104 may switch off. This
shutdown may trigger these network switches to shutdown the matching Ethernet port for at least one minute.
This shutdown on the switch side can prevent software download.
To prevent this, the Mediatrix 4104 supports the STP. However, this management has a potential time cost. It
may appear from time to time that software downloads take more time. This is normal.
The following is an example where the STP management impacts the download duration.

The software download procedure does not use any DHCP and DNS services.

The primary image server is down (or not properly configured).

The secondary image server is up and running well.
In this case, the Mediatrix 4104 tries to contact the primary image server. As it is not available, the Mediatrix
4104 retries for two minutes. It contacts the secondary server after that period and starts the software
download.
Note:
When using the Mediatrix 4104, Media5 recommends to disable the Spanning Tree Protocol on the
network to which the unit is connected.
