C1130-k9w7-tar.124-3g.ja1.tar -

1. Filename Breakdown

| Part | Meaning | | :--- | :--- | | C1130 | Target platform: Cisco Aironet 1130 series (e.g., AIR-AP1130AG). | | -k9w7 | Feature set / image type:
• k9 = Cryptography (SSL/TLS, SSH, AES support).
• w7 = Lightweight Access Point (LAP) image (Mobility Express or similar; this specific one is a hybrid image). | | -tar | File format: TAR archive (contains multiple files: IOS image, web management files, etc.). Not a simple .bin file. | | 124-3g.JA1 | IOS version: 12.4(3g)JA1.
• 12.4 = major IOS version.
• 3g = maintenance release.
• JA1 = specific access point train (older, replaced by JA2, etc.). | | .tar | Archive extension – must be extracted or loaded via specific procedures. |

Cautions

• Do not use this file on autonomous APs (e.g., if running IOS in AP mode without a controller).
• Confirm WLC model supports LWAPP (older 1130AG units do not support CAPWAP without an intermediate upgrade path).
• Verify checksum/MD5 before flashing to avoid corruption.

7. Limitations & Compatibility

• Device Compatibility:
  • This firmware is specific to the Cisco Catalyst 1130 series.
  • Use incompatible versions to avoid bricking the device.
• Wireless Features:
  • Supports 802.11n/g/b standards (based on "w7").

Upgrade Methods

1. Controller-initiated – Predownload via WLC:
   config ap image predownload primary C1130-k9w7-tar.124-3g.JA1.tar
2. Manual TFTP from bootloader (ROMmon) – Use archive tar /xtract or tar –x after booting into a recovery image.
3. HTTP/TFTP from autonomous mode – Not applicable unless image is converted (this is pure lightweight).

1. Purpose of the File

This file is a Cisco IOS (Internetwork Operating System) firmware image, specifically tailored for a Cisco Catalyst 1130 series wireless access point. It includes: C1130-k9w7-tar.124-3g.JA1.tar

• The core operating system for the device.
• Wireless capabilities (Wi-Fi support).
• Cryptographic security features (encryption, authentication).

Method B – Via recovery / bootloader (if AP is bricked):

At the ap: bootloader prompt:

ap: set IP_ADDR <AP-IP>
ap: set NETMASK <subnet-mask>
ap: set DEFAULT_ROUTER <gateway-ip>
ap: tar -xtract tftp://<tftp-ip>/C1130-k9w7-tar.124-3g.JA1.tar flash:
ap: boot
