Information".
The amplifier's internal memory contains a histogram log, which allows CPI personnel to easily
understand the long term operating conditions that the amplifier has experienced. This log can be
downloaded and examined and can be helpful in identifying trends and potential problems. The
three different histograms kept in the Indoor SSPA's memory are brick temperature vs. operating
hours, individual fan rpm vs. operating hours, and inlet air temperature vs. operating hours.
The snapshot fault capture log is used to capture in-depth information around any amplifier fault
activity. This enables quick and accurate diagnosis of problems by trained CPI personnel. The
fault snapshot log can hold up to five entries. Entries over five overwrite the oldest entry.

6.2 Scheduled Preventive Maintenance

Note: There are additional preventive maintenance tasks that require a
service technician who has attended a formal training program for
servicing the Indoor SSPA. (See Table 6-2).
To function safely and effectively, the Indoor SSPA requires periodic maintenance by the operator.
No maintenance is required for the electrical components inside the Indoor SSPA unit.
The chassis may be periodically cleaned with a mild detergent and water. Do not use Genesolv,
Benzene, Toluene, or similar solvents on any part of the chassis or the connection ports.
Refer to Table 5-1 for the Preventive Maintenance tasks to be performed by operators. Table 5-2
outlines preventive maintenance tasks to be performed by a service technician.
Operator Preventive maintenance includes visual inspection and cleaning per Table 5-1. Most of
these tasks are performed with the AC power removed. Details are listed in the following
