Cisco Cisco 521 Wireless Express Access Point Installationsanleitung

Slightly rotate the access point from side-to-side until you hear the 
second keyhole clip falling into the other keyhole that is located on 
the opposite end of the access point and not visible.

Slide the access point back over the keyhole clips. You will hear a 
click when the locking detent contacts the access point and locks it 
into place.

There are two ways you can secure your access point:

Using a security cable

Securing the access point to the mounting plate

You can secure the access point by installing a standard security cable (such 
as the Kensington Notebook MicroSaver, model number 64068) into the 
access point security cable slot. The security cable can be used with any of 
the mounting methods described in this guide.
