If either of these calls fail then TCP and/or UDP inbound data is being blocked on the failed
connection (see "Troubleshooting TCP Port Blocking" above).
Testing your Codec
·
Visit www.tieline.com or contact Tieline for a list of test IP codec addresses you can use to verify
your codec is configured correctly.
·
See Testing IP Network Connections for more IP test information.
26 Reference
The following sections contain reference and troubleshooting information.
26.1 Regular Maintenance
Tieline recommends the codec undergoes regular maintenance to ensure operational efficiency and
prolong its life.
WARNINGS: All work should be carried out by suitably qualified personnel. Remove both
power leads from the codec before removing the cover. All parts are mounted on plugs and
only a Philips screwdriver is required. Ensure that fan mounting lugs are not hooked out by
the cover.
Maintenance Schedule
Tieline recommends a three year maintenance schedule which includes the following procedures to
be completed:
1. Evacuate all dust from the unit and clean vents.
2. Replace both PSUs.
3. Replace the fan.
Controlled rack environments may allow a longer maintenance cycle. Uncontrolled environments,
where temperatures are elevated, may require a shorter maintenance cycle.
Tieline recommends that the racks in which codecs are installed are thoroughly evacuated to ensure
proper airflow from the bottom to the top. Where space is available, a 1RU gap between codecs will
assist in minimizing internal temperature build up. Tieline has incorporated dual redundant PSUs
and backup temperature alarm features to assist in maintaining reliable operations. The fan has
been carefully chosen for long life operation and should not be replaced by a cheaper equivalent. If
rack temperatures are elevated above 40 degrees Celsius, the fan speed will increase to reduce
CPU temperature. Maximum fan speed is reached when the temperature reaches 45 degrees
Celsius. Fan speed control circuitry reduces the fan speed as internal rack temperatures fall below
45 degrees Celsius. This greatly extends the working life of the fan and the codec.
