6. Maintenance And Inspection
Preventive maintenance and inspection is required to maintain the communication
interface in its optimal condition, and to ensure a long operational lifetime.
Depending on usage and operating conditions, perform a periodic inspection once
every three to six months. Before starting inspections, always turn off all power
supplies to connected drives, and wait at least five minutes after each drive’s
“CHARGE” lamp has gone out.
DANGER!
Do not touch any internal parts with power applied
to the drives, or for at least 5 minutes after power to the drives has been
removed. A hazard exists temporarily for electrical shock even if the source
power has been removed.
Inspection Points
• Check that the dust covers for all unused RJ45 ports are seated firmly in their
connectors.
• Check that the drive and network communication cables are not loose. Tighten /
reseat as necessary.
• Where applicable, check that there are no defects in any attached grounding wire
terminal crimp points. Visually check that the crimp points are not scarred by
overheating.
• Visually check all wiring and cables for damage. Replace as necessary.
• Clean off any accumulated dust and dirt.
• If use of the interface is discontinued for extended periods of time, apply power at
least once every two years and confirm that the unit still functions properly.
• Do not perform hi-pot tests on the drives or interface, as they may damage the
units.
Please pay close attention to all periodic inspection points and maintain a good
operating environment.
