6. Maintenance And Inspection

Preventive maintenance and inspection is required to maintain the ETH-100 Ethernet
interface in its optimal condition, and to ensure a long operational lifetime.

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!
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 Ethernet communication cables are not loose. Reseat if
necessary.
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 ETH-100 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 ETH-100 interface, as they may
damage the units.
Please pay close attention to all periodic inspection points and maintain a good
operating environment.
Do not touch any internal parts with power applied
