Maintenance
Exterior Cleaning
Clean the exterior surfaces of the chassis with a dry lint-free cloth or a soft-bristle brush. If any
dirt remains, wipe with a cloth moistened in a mild soap solution. Remove any soap residue by
wiping with a cloth moistened with clear water. Do not use abrasive compounds on any part of
the chassis.
Caution
Avoid getting moisture inside the chassis during exterior cleaning,
especially through the top vents. Use just enough moisture to dampen the cloth.
Do
not
wash the front- or rear-panel connectors or switches. Cover these components
while cleaning the chassis.
Do
not
use harsh chemical cleaning agents; they may damage the chassis. Avoid
chemicals that contain benzene, toluene, xylene, acetone, or similar solvents.
Cleaning the Fan Filters
Dirty fan filters can dramatically affect the cooling performance of a NI PXIe-1082 chassis.
Clean the filters whenever they become visibly dirty. You can easily remove the chassis air
filters from the rear of the chassis by removing the filter retainer. To remove the filter retainer,
loosen the retainer screw. The filter cover and retainer are shown in Figure 1-2,
Rear View of the
NI PXIe-1082 Chassis
.
Clean the fan filters by washing them in a mild soap solution and then vacuuming or blowing air
through them. Rinse the filters with water and allow them to dry before reinstalling them on the
chassis.
Resetting the AC Mains Circuit Breaker
If the NI PXIe-1082 chassis is connected to an AC source and encounters an over-current
condition, the circuit breaker on the rear panel will trip to prevent damage to the chassis.
Complete the following steps to reset the circuit breaker.
1.
Turn off the chassis.
2.
Disconnect the AC power cable.
3.
Depress the circuit breaker to reset it.
4.
Reconnect the AC power cable.
5.
Turn on the chassis.
If the circuit breaker trips again, complete the following steps:
1.
Turn off the chassis.
2.
Disconnect the AC power cable.
3.
Remove all modules from the chassis.
