S
OLUTION
: Perform a recovery mode or a factory reset procedure after proceeding with the downgrade
operation.
• If you perform a recovery mode as per “Recovery Mode” on page 19 , you must
manually change the default router IP address to a valid address other than 0.0.0.0,
then restart the Mediatrix 4104.
• If you perform a factory reset procedure as per “Factory Reset” on page 20 , everything
should be working properly. However, this deletes any custom setting you may have
done in other variables as it reverts the Mediatrix 4104 back to its default factory
settings.
D
ESCRIPTION
: The TFTP server does not recognize the download path and produces an error.

OSSIBLE
C
AUSE
: You should use the “/” character when defining the path to indicate sub-directories,
i.e., c:/temp/download . However, some TFTP servers on the Windows operating system do not
recognize the “/” character and produce an error.
S
OLUTION
: Use the “\” character in the path definition.
D
ESCRIPTION
: Performing a software download takes an unusually long time.

P
OSSIBLE
C
AUSE
: If the following happens:
• Any information is set to come from the DHCP server (for example, the SNTP server
address) and the DHCP server cannot be reached.
• The primary software server address is invalid (either set by DHCP or static).
The unit tries to reach the primary software server without realizing that the address is invalid. It keeps
trying for a few minutes, even if the download procedure fails.
This delay is caused by the Mediatrix 4104 that cannot function as configured if part of its configuration
(the DHCP information) is unavailable. Furthermore, there is an issue with switches that use the
Spanning Tree Protocol. When this protocol is enabled, the Mediatrix 4104 may be denied from the
network for a certain time, which causes the long delay.
S
OLUTION
: Media5 recommends to set up all information to use a valid static value, or have a DHCP
server answer the requests. See “Static Configuration” on page 143 for more details.
SNMP Management Software Issues
The following are issues you may encounter when trying to contact the Mediatrix 4104 with a SNMP
management software.
D
ESCRIPTION
: The SNMP network management software cannot access the Mediatrix 4104.

P
OSSIBLE
C
AUSE
: The SNMP network management software does not have the proper Mediatrix 4104
information.
S
OLUTION
: Check that:
• The IP information for the Mediatrix 4104 is correctly configured.
• The Mediatrix 4104 was restarted after defining the IP information.
• The line through which you are trying to access the Mediatrix 4104 has been unlocked
or is not the correct line. If it is locked, check the connections and network cabling for
the connector.
