Reference Criteria
Protective system
maintenance
(1) Check the cabinet top and
inside for cleanliness.
(2) Check whether the rodent-
proof net on each signal cable
outlet at the cabinet top or
bottom is tightly wrapped and in
good condition.
(1) Check the cabinet top and
inside for cleanliness.
(2) All rodent-proof nets should
be tightly wrapped and
undamaged.
Dust-proof system
maintenance
(1) Check the cabinet cover for
cleanliness.
(2) Check the air filter at the
cabinet bottom for cleanliness.
(3) Check the air filter gauze at
inner side of the cabinet's front
door for cleanliness.
(1) The cabinet cover and the air
inlet at the cabinet bottom should
be free from dusk and cabinet air
supply is unblocked and the air is
clean.
(2) All air filter frames and gauze
are clean and free from dust.

Procedure
Step 1
Use a multimeter to check the grounding of each cabinet component:
l
Set the multimeter to the resistance position and connect one lead to a fixed place in the
equipment room (you may need to extend the lead cable) and the other lead to measure each
grounding point inside the cabinet. Given the measuring accuracy, the measured resistance
of each grounding point should be approximately 1 ohm or less. If the resistance measured
at a grounding point exceeds 1 ohm, check the grounding cable, connecting terminal and
fastening screw and make appropriate corrections.
l
Set the multimeter to the voltage position and connect one lead to a fixed place in the
equipment room (you may need to extend the lead cable) and the other pointer to measure
each grounding point inside the cabinet. Given the measuring accuracy, the voltage measured
at each grounding point should range between 0 V and 5 V. If the voltage measured at a
grounding point is 0 V, the point is not grounded. In the case of a value larger than 5 V, check
the grounding cable, connecting terminal and fastening screw at the grounding point and
make appropriate corrections.
Step 2
Remove the air filter frame from the cabinet bottom. Wash and dry the filter thoroughly and
then place it back into the cabinet.
Step 3
Remove the air filter gauze from the inner side of the cabinet's front door. Dehydrate the gauze
and let it dry. Then, replace.
Step 4
Take out the air deflector from inside the jamb on the cabinet's front side. Use a piece of clean
cotton gauze, an anti-static brush, or a vacuum cleaner. Then replace.
