Chapter 3 Installing the 1552 Series Access Points in Hazardous Locations
Performing Maintenance
Removing the Access Point from Service
When removing an access point from service, make sure you remove power from the access point before
opening the cover and disconnecting the AC input wiring. When removing the AC wiring, the ground
connection should be the last to be disconnected.
Conducting Periodic Inspections
The access point should be inspected periodically to ensure normal and airtight operation in the
hazardous location environment.
Table 3-3 lists the inspection routines and their periodicity.
Conducting Periodic Cleaning
The access point is designed to not require periodic cleaning.
What to Do Next
When you power up a MAP that is not connected to a wired Ethernet, fiber-optic, or cable network to
the controller, the access point uses the Cisco Adaptive Wireless Path Protocol (AWPP) to bind to
another mesh access point (MAP) with the best path to a root access point (RAP) connected to the wired
network to a controller. The access point sends a discovery request when powered up. If you have
configured the access point in the controller correctly, the controller sends back a discovery response to
the access point. When that happens, the access point sends out a join request to the controller, and the
controller responds with a join confirmation response. Then the access point establishes a Control And
Provisioning of Wireless Access Points (CAPWAP) connection to the controller and gets the shared
secret configured on the controller.
Refer to the Cisco Wireless LAN Controller Configuration Guide for more information on configuring,
monitoring, and operating your access points.
