Regular Maintenance
Contents
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 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. Fan speed control circuitry reduces the fan speed as internal rack temperatures fall below 25 degrees Celsius. This greatly extends the working life of the fan and the codec. If rack temperatures are elevated above 25 degrees Celsius, the fan speed will increase to reduce CPU temperature.
