CHAPTERFirst Draft - CISCO CONFIDENTIAL7-1Cisco Aironet 1100 Series Access Point Hardware Installation GuideOL-4309-0272.4 GHz Radio UpgradeThis chapter provides upgrade instructions for the 2.4-GHz (IEEE 802.11b-compliant or IEEE 802.11g-compliant) radio card and includes the following sections:•Upgrade Overview, page 7-2•Unpacking the Radio, page 7-2•Removing the Back Cover, page 7-3•Removing a 2.4-GHz Radio, page 7-4•Installing a 2.4-GHz Radio, page 7-5•Replacing the Back Cover, page 7-8

First Draft - CISCO CONFIDENTIAL7-2Cisco Aironet 1100 Series Access Point Hardware Installation Guide OL-4309-02Chapter 7 2.4 GHz Radio UpgradeUpgrade OverviewUpgrade OverviewThis section provides instructions for upgrading the access point 2.4-GHz radio. The following operations summarize the upgrade procedure: 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.Caution 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.Note 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 RadioEach 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.

Step 1 Gently lift the top of the antenna card until it clears the plus shaped (+) support post (see Figure 7-2).Figure 7-2 Radio Card and Antenna CardStep 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: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.Step 5 Place the radio card and antenna card on the ESD-protected work surface.1Support post 4Radio Card2Antenna card 5Card-retaining clips3Support bracket 6Mini-PCI connector

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.Figure 7-3 Antenna WiresStep 7 Place the removed 2.4-GHz radio card into an anti-static bag. The antenna card will be connected to your new radio card.Go to the “Installing a 2.4-GHz Radio” section.Installing a 2.4-GHz RadioTo install a new 2.4-GHz radio card into the access point, follow these steps: Caution The internal access point components and the 2.4-GHz radio can be damaged by ESD from improper handling. Step 1 Carefully remove the new Cisco Aironet 2.4-GHz radio card from its anti-static bag.Step 2 Grasp the radio card only on the edges, being careful not to touch components on the board or the gold connector pins.Step 3 Place the radio card on the anti-static work surface next to the antenna card.1Antenna card 2Radio card

Caution The antenna connectors can be damaged by using a pair of long-nose pliers.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).Figure 7-4 Inserting Radio Card in Mini-PCI Connectorb. Push the radio card into the mini-PCI connector until it clicks into place.Step 6 Hold the top of the antenna card and carefully push the radio 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).1Antenna card 3Mini-PCI connector2Radio card
