4.1. Maintenance
Maintenance of the iPump 6420 is limited to keeping the chassis clean and ensuring that
cables remain firmly connected. Occasionally wipe the exterior with soft, damp cloth to remove
any accumulated dust and dirt, in order to keep the air vents clear.
Occasionally monitor the unit’s temperature indication to see that it remains fairly constant
while in use in a static location. A sudden increase in the baseline daily temperature, with no
other explanation, may indicate a failure in an internal ventilation fan. If the unit temperature
increases, and this may be attributable to a hotter ambient environment, then it is suggested that
some effort be made to improve the local cooling. The iPump 6420 will give a much longer
operating lifetime if kept cool.
Occasionally monitor the unit for any Warnings about over-temperature or HDD problems.
This is especially important if the HDD has seen more than 5 years of operation.
The iPump 6420 incorporates security labels over some of the chassis screws. There are no
user-serviceable components within the iPump 6420. Tampering with security labels or opening
the unit will void your warranty, unless you are given written permission by WEGENER
Customer Service or some other authorized WEGENER representative. If you have any
questions, contact WEGENER’s Customer Service Department at the street address, email
address, or phone numbers listed under Customer Service.
4.2. Troubleshooting
When the common system problems occur, and they will, it is best to first consult the first
three chapters of this Manual. After that, look for your problem in the following subsections and
then review the checklists given. Following that, if there is still a problem, call WEGENER
Customer Service for assistance.
4.2.1. Failure to acquire a carrier
1. Sure you do not have carrier lock? Check CARRIER LED.
2. Is signal level displayed on Front-panel between 10 and 90? If only 0, then
functioning LNB is probably not connected to the i6420, or i6420 internal receiver
card is failed.
3. RF input cable securely attached?
4. External LNB powered with DC? Is LNB DC from unit ON?
5. Correct tuning parameters: Carrier frequency, data-rate, FEC ratio?
6. Are carrier ID tags required? Is carrier tag set correctly in i6420?
7. Can other receivers on same antenna lock to this carrier?
