3.3 Powering the Phone
The Cisco SPA504G IP Phone supports Power over Ethernet (PoE). If your network switch provides PoE, the phone will power on automatically once connected to the network. If PoE is not available, an optional Cisco PA100-NA power supply (sold separately) is required. Connect the power supply to the 'DC 5V' port on the back of the phone and then to a power outlet.
4. Operating the Phone
4.1 Display and Navigation
The phone features a monochrome backlit LCD display that shows call information, menu options, and status indicators. Navigation is primarily done using the four soft-key buttons directly below the display and the four-way navigation cluster with a select button in the center.

5. Maintenance
5.1 Cleaning
To clean the phone, use a soft, dry, lint-free cloth. For stubborn marks, a slightly damp cloth with mild, non-abrasive cleaner can be used. Avoid spraying liquids directly onto the phone or using harsh chemicals.
5.2 Firmware Updates
Periodically check the official Cisco support website for available firmware updates for the SPA504G. Firmware updates can improve performance, add new features, and address security vulnerabilities. Follow the instructions provided by Cisco for the update process, which typically involves downloading the firmware file and accessing the phone's web-based administration interface.
6. Troubleshooting
6.1 Common Issues and Solutions
| Issue | Possible Cause | Solution |
|---|---|---|
| Phone does not power on | No PoE or missing/faulty power supply | Ensure PoE is active on the network port or connect the optional Cisco PA100-NA power supply. Verify power supply functionality. |
| "Initializing Network" message persists | Network connectivity issue or incorrect network settings | Check Ethernet cable connection. Verify network settings (IP address, subnet mask, gateway, DNS) through the phone's menu or web interface. Consult your network administrator. |
| No dial tone or unable to make calls | SIP/SPCP registration failure or service provider issue | Verify SIP/SPCP account settings. Ensure the phone is registered with your VoIP service provider. Contact your service provider for assistance. |
| Poor voice quality (echo, static) | Network congestion or faulty cables/handset | Check network bandwidth. Replace handset cord or handset if necessary. Ensure proper network configuration for VoIP traffic. |
6.2 Factory Reset
A factory reset will erase all custom configurations and restore the phone to its default settings. This should only be performed as a last resort for troubleshooting. Refer to the Cisco support documentation for the specific procedure to perform a factory reset on the SPA504G, as it often involves a sequence of button presses during startup.
