Hardware Diagnostics; Firmware Recovery - Cisco 7925G Deployment Manual

Hardware Diagnostics

As of the 1.3(4) release, a self-diagnostics tool is available that can help with hardware analysis.
The Diagnostics menu is located under the Phone Settings menu, where the Keypad, Speaker and Microphone, Barcode
Scanner, and Wireless LAN Radio and Antenna can be validated.
The keypad diagnostics allows for a button to be pressed and released to ensure they are functional.
The audio diagnostics performs an audio loopback, so the speaker and microphone can be validated.
The WLAN diagnostics menu is the standard Site Survey utility, which will use the current network profile information to
perform passive and active scans for the configured SSID and 802.11 mode.
The scanner diagnostics will allow to scan a 2D barcode to ensure the scan engine is functional. A Reset option is available to
reinitialize the barcode scanner.
