SIS-1500 Seafloor Imaging System 5-3
SECTION 5 Maintenance and Troubleshooting Processor Periodic Maintenance
he routine maintenance of the SIS-1500 Seafloor Imaging System
primarily involves the periodic inspection of the SIP-150 Sonar Image
Processor air filters, the backing up of the processor’s internal hard
drive, and the washing and inspection of the TTV-195 tow vehicle. This
section encompasses the maintenance procedures that will help ensure
continued, reliable performance from the system, and troubleshooting guides
that will assist in isolating and correcting any problems that may be
encountered during setup and deployment. Also, a list of recommended test
equipment, tables of downlink commands and uplink data, and check and
calibration procedures are provided. This information can be used for
troubleshooting any performance problems or hardware failures.
Processor Periodic Maintenance
The SIP-150 Sonar Image Processor is built from highly reliable components
and requires a minimum of maintenance; however, to maintain the best
performance and to avoid premature hardware failures, periodic
maintenance should be performed. This includes cleaning the air filters,
making backups, and using hard disk maintenance utilities.
Air Filter Cleaning
The topside processor’s workstation has three air filters: two are located on
the back panel and the third is located behind the vent plate on the front
panel. To remove the filters on the back panel of the workstation, first snap
the filter covers off, and then remove the filters and clean or replace them. To
remove the filter on the front panel of the workstation, first unscrew the vent
plate, and then remove and clean or replace the filter.
Backups
It is recommended that the workstation’s internal hard drive be backed up on
a regular basis. This will ensure, should the hard drive fail, that it can be
restored to its original configuration, hence eliminating time-consuming
T
NOTE Keeping the air filters clean is important. Dirty air filters will restrict
the flow of cooling air to the hardware components which can cause heat
damage and failure.
