Performing Maintenance
The access point requires minimal periodic or preventive maintenance as it has no moving parts, filters,
lubricants, or mechanical contact components. However, when installed in a hazardous location, periodic
inspections should be conducted in order to ensure that the access point is operating satisfactory. This
section provides information about performing maintenance on an access point installed in a hazardous
location.
Additional maintenance information can be found in Chapter 4, “Troubleshooting” and the
