Upgrade Overview
This section provides instructions for upgrading the access point 2.4-GHz radio. The following
operations summarize the upgrade procedure:
Caution
Note
1.
Remove all cables and power connections from the access point.
2.
Follow standard electrostatic discharge (ESD) procedures.
3.
Place the access point on an ESD-protected work surface.
4.
Remove the access point’s back cover.
5.
Remove the existing 2.4-GHz radio card.
6.
Install the new 2.4-GHz radio card.
7.
Replace the access point’s back cover.
8.
Install the new compliance labels.
ESD can damage the Cisco Aironet radio and the internal components of the access point. It is
recommended that the 2.4-GHz radio upgrade procedures be performed by an ESD-trained service
technician at an ESD-protected workstation.
After you install the new radio, all configurable radio settings will be at default values. Refer to the Cisco
IOS Software Configuration Guide for Cisco Aironet Access Points for complete instructions on
configuring the new radio.
Unpacking the Radio
Each 2.4-GHz (IEEE 802.11G) radio is shipped with the following items:
•
Quick start guide
•
A product registration card
•
A T-10 tamper-resistant Torx L-wrench (not used on 1100 series access points)
•
Two 1100 series access point labels
•
A 1200 series access point 2.4-GHz radio compliance label (not used on 1100 series access points)
If anything is missing or damaged, contact your Cisco representative for support.

Removing the Back Cover
Fi r st Dr aft - CISCO CON FIDENTIAL
Removing the Back Cover
To remove the access point’s back cover, follow these steps:
Step 1
Remove all cables and power connections from the access point.
Step 2
Remove all static-generating items from the work area, such as plastic material, styrofoam cups, and
other similar items.
Step 3
Place the access point and the new 2.4-GHz radio (in its antistatic bag) on an antistatic work surface.
Step 4
Discharge any static buildup on your body by touching a grounded surface (antistatic work surface)
before proceeding.
Step 5
Position the access point so that the back cover is facing up.
Caution
Step 6
The internal access point components and the 2.4-GHz radio can be damaged by ESD from improper
handling.
Remove the back cover retaining screw using a philips screwdriver (see Figure 7-1).

Step 2
Gently pull the antenna card to remove it from the notch in the support bracket. Do not disconnect the
antenna wire connectors.
Step 3
Push the card-retaining clips (on each side of card) away from the radio card (see Figure 7-2). When
released, the radio card springs up. Do not disconnect the antenna wires.
Step 4
Remove the 2.4-GHz radio card from the mini-PCI connector by performing the following operations:
Step 5
a.
Grasp the radio card only on the edges, being careful not to touch components on the board or the
gold connector pins.
b.
Remove the 2.4-GHz card from the mini-PCI connector.
Place the radio card and antenna card on the ESD-protected work surface.

Step 6
Use your fingers to carefully remove the antenna wire connectors from the 2.4-GHz radio card. Do not
remove the antenna wire connectors from the antenna board.
Caution
The antenna connectors can be damaged by using a pair of long-nose pliers during the removal
process.
Caution
To avoid damaging the antenna wire assemblies, handle them by their connectors.
