31 Maintenance
The I128 does not require routine maintenance, except to clear any dust accumulation in the fan
filter.
There are no user-serviceable parts inside.
CAUTION. High voltages may be present inside the case. Do not open the case when power is
applied.
31.1 Cooling fan maintenance
If there is buildup of dust in the filter, you should clear this by vacuum cleaning in situ, or by
removing the filter element and cleaning it separately with an air jet. Note that detaching the
filter element also detaches the fan from the case.
Figure 66. Fan filter removal
If the fan fails, it is necessary to open remove the lid of the case to access the power connector.
Due to risk of contamination or electrostatic discharge damage, we recommend that you consult
Pyramid Technical Consultants, Inc. before attempting this.
