Setup and Installation
Follow these steps to properly set up your Cisco SPA 508G IP Phone:
- Unpacking: Carefully remove all components from the packaging. Verify that all parts are present, including the phone unit, handset, handset cord, and Ethernet cable. Note: This product typically does not include a separate power adapter as it is designed for Power over Ethernet (PoE). If PoE is not available, a compatible AC power adapter must be purchased separately.
- Connecting the Handset: Plug one end of the coiled handset cord into the handset and the other end into the handset port on the phone base.
- Network Connection (PoE): Connect one end of the Ethernet cable to the "SW" (Switch) port on the back of the phone and the other end to a PoE-enabled network switch or router. The phone will power on automatically.
- Network Connection (Non-PoE with AC Adapter): If not using PoE, connect a compatible AC power adapter (purchased separately) to the power port on the phone and then to a power outlet. Connect one end of the Ethernet cable to the "SW" port on the phone and the other end to your network switch or router.
- PC Connection (Optional): If you wish to connect a computer through the phone, connect an Ethernet cable from your computer to the "PC" port on the back of the phone. This allows your computer to share the network connection provided to the phone.
- Initial Boot-up: The phone will display a boot-up sequence. Once complete, it will attempt to obtain network settings and register with your VoIP service provider. This process may take a few minutes.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your IP phone.
