Upgrade Overview
Fi r st Dr aft - CISCO CON FIDENTIAL
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.
Open the access point’s 2.4-GHz radio access cover.
5.
For an access point without a 2.4-GHz radio feature, remove the blank spacer card.
6.
For an access point with a 2.4-GHz radio feature, remove the existing 2.4-GHz radio card.
7.
Install the new 2.4-GHz radio card.
8.
Close the access point 2.4-GHz radio access cover.
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 radio is shipped with the following items:
•
Quick start guide
•
A product registration card
•
A T-10 tamper-resistant Torx L-wrench
•
A 2.4-GHz radio compliance label
If anything is missing or damaged, contact your Cisco representative for support.

Opening the Access Cover
Fi r st Dr aft - CISCO CON FIDENTIAL
Opening the Access Cover
To open the 2.4-GHz radio access 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 bottom cover is facing up.
Caution
The internal access point components and the 2.4-GHz radio can be damaged by ESD from improper
handling.
Step 6
Remove the bottom access cover using the T-10 tamper-resistant Torx L-wrench provided with your
Cisco radio card (see Figure 7-1).

If your access point was not configured with a 2.4-GHz radio, go to the “Removing a Blank Spacer Card”
section. If you are replacing an existing 2.4-GHz radio, go to the “Removing a 2.4-GHz Radio” section.

2.4-GHz Radio Upgrade
Removing a Blank Spacer Card
Fi r st Dr aft - CISCO CON FIDENTIAL
Removing a Blank Spacer Card
When your access point is not factory-configured with a 2.4-GHz radio, it contains a blank spacer card
in the internal mini-PCI connector. You must remove the blank spacer card prior to installing a new
2.4-GHz radio card.
Caution
Handle all components carefully and observe all ESD precautions. The internal access point components
and the 2.4-GHz radio can be damaged by ESD from improper handling.
To remove the blank spacer card from the mini-PCI connector, following these steps:
Step 1
Push the card-retaining clips (on each side of card) away from the card (see Figure 7-2). When released,
the board springs up.

Step 4
To avoid damaging the antenna wire assemblies, handle them by their connectors.
Remove the blank spacer card from the mini-PCI connector.
For instructions on installing the radio card, go to the “Installing a 2.4-GHz Radio” section.
Removing a 2.4-GHz Radio
To remove a 2.4-GHz radio card from your access point, follow these steps:
Caution
Step 1
The internal access point components and the 2.4-GHz radio can be damaged by ESD from improper
handling.
Use your fingers to carefully remove the antenna wire connectors from the 2.4-GHz radio card.
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.

Step 5
Insert the radio card into the access point’s mini-PCI connector by following these steps:
a.
Tilt the radio card at approximately 20o to 30o so that its gold pins are aligned with the mini-PCI
connector (see Figure 7-4).
b.
Push the card into the mini-PCI connector until it clicks into place.
Step 6
Carefully push the card down (towards the access point’s motherboard) until the card-retaining clips lock
into the notches on the side of the radio card (you will hear a click).
Step 7
Carefully position the antenna wires so that the metal connectors do not touch each other.
Caution
Damage to the radio could occur if the antenna connectors are touching when power is applied. If they
are touching, carefully rotate them in opposite directions until they are separated.
Step 8
Reinstall the 2.4-GHz radio access cover and use the T-10 tamper-resistant Torx L-wrench to tighten the
cover’s retaining screw.
Step 9
Remove the backing paper from the 2.4-GHz radio compliance label.
Step 10
Carefully attach the label in the space provided below the access point’s product compliance label as
shown in Figure 7-5.

Note
If your access point contains a 5-GHz radio module, there is also a 5-GHz radio compliance label
on the back of the unit.
Note
If you access point has an existing 2.4-GHz radio compliance label, place your new 2.4-GHz
radio compliance label over the existing label.
The radio card installation is now complete. To configure the radio with your wireless network settings,
refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points.
