D
ESCRIPTION
: An error occurs when the Mediatrix 1204 attempts to transfer the software upgrade.
P
OSSIBLE
C
AUSE
: The Ethernet cable has become disconnected from the Mediatrix 1204 or the PC
running the file transfer.
S
OLUTION
: Reconnect the cable and start again.
P
OSSIBLE
C
AUSE
: Power to the Mediatrix 1204 has been disrupted during the file transfer.
S
OLUTION
: Check the power connection to the Mediatrix 1204 and start again.
D
ESCRIPTION
: When downgrading the Mediatrix 1204 to a previous version of the application software, the
unit does not restart, the LAN LED is blinking and all other LEDs are off.
P
OSSIBLE
C
AUSE
: The default router IP address is set to 0.0.0.0, which is not supported by the version
to which you downgraded.
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 20 , you must
manually change the default router IP address to a valid address other than 0.0.0.0,
then restart the Mediatrix 1204.
• If you perform a factory reset procedure as per “Factory Reset” on page 21 , everything
should be working properly. However, this deletes any custom setting you may have
done in other variables as it reverts the Mediatrix 1204 back to its default factory
settings.
D
ESCRIPTION
: The TFTP server does not recognize the download path and produces an error.
P
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 1204 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 1204 may be denied from the
network for a certain time, which causes the long delay.
S
OLUTION
: Mediatrix 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 119 for more details.
