Troubleshooting

You can experience some problems when connecting the Mediatrix 4104 to the network. The following section
examines some of these problems and possible solutions.

A Syslog message lists the problems the Mediatrix 4104 encounters. You can see this message with the
Syslog daemon.

This chapter covers the following types of issues:



General Operation Issues



Calling Issues



Fax Issues



Configuration Issues



Software Upgrade Issues



SNMP Management Software Issues

General Operation Issues

The following are general operation issues you may encounter.

D

ESCRIPTION

: Unit does not operate – All LEDs are OFF.



P

OSSIBLE

C

AUSE

: Power is not fed to the unit.

S

OLUTION

: Check that:

•

The power cord is connected to the electrical outlet.

•

The power cord is fully inserted into the Mediatrix 4104 power socket.

D

ESCRIPTION

: There is a long delay when starting the Mediatrix 4104.



P

OSSIBLE

C

AUSE

: If any information is set to come from the DHCP server (for example, SNTP address),

the restarting unit waits for a maximum period of two minutes if the DHCP server cannot be reached,
even if most other settings are set to “static”.

This delay is caused by the Mediatrix 4104 that cannot function as configured if part of its configuration
(the DHCP information) is unavailable.

The two minutes waiting period is an issue with switches that use the Spanning Tree Protocol. When
this protocol is enabled, the restarting Mediatrix 4104 may be denied from the network for a certain time
(about two minutes). The unit must not ignore transmission errors (i.e., timeouts) because these errors
might be caused by the Spanning Tree Protocol.

S

OLUTION

: Media5 recommends to set up all information to use a static value, or have a DHCP server

answer the requests. See

“Static Configuration” on page 143

for more details.
