Chapter2 Installing the Ac cess Point
Mounting Above a Suspended Ceiling
Follow these steps to mount your access point on a suspended ceiling:
Step1 Decide where you want to mount the access point.
Step2 Attach two T-rail clips to the suspended ceiling T-rail.
Step3 Use the mounting plate to adjust the distance between the T-rail clips so that they align with the holes in
the mounting plate.
Step4 Use a standard screwdriver to tighten the T-rail clip studs in place on the suspended ceiling T-rail. Do
not overtighten.
Step5 If using recessed ceiling tiles, install a plastic spacer on each T-rail clip stud. The spacer’s legs should
contact the suspended ceiling T-rail.
Step6 Attach the mounting plate to the T-rail clip studs and start a Keps nut on each stud.
Step7 Use a wrench or pliers to tighten the Keps nuts. Do not overtighten.
Step8 To attach the access point to the mounting plate, see the “Attaching the Access Point to the Mounting
Plate” section on page 2-16.
Step9 If you need additional security, refer to the “Securing the Access Point” section on page2-17 for
additional information.
Step10 Verify the access point is operating (see the “Powering Up the Access Point” section on page2-22).
Mounting Above a Suspended Ceiling
The access point mounting plate is designed to be integrated into the T-bar grid above the tiles of a
suspended ceiling. Using a T-bar box hanger and bracket mounting clip (not supplied) such as the
Erico 512A and BHC, you orient the access point antenna just above the top surface of a standard ceiling
tile. You may need to modify a thicker tile to allow room for the antenna.
