Cisco IP Phone Key Expansion Module Setup Overview

Key expansion modules add extra line appearances, speed dials, or programmable buttons to the phone. The
programmable buttons can be set up as phone line buttons, speed-dial buttons, or phone feature buttons

Caution

The slots in the side of the phone are designed only for use with the spine connectors on the key expansion

Key Expansion Module Power Information

If you use a key expansion module with your phone then Power over Ethernet (PoE) is enough to power your
expansion modules. But a power cube is needed for smartphone or tablet charging when your expansion
module is attached.

A key expansion module uses 48V DC, 5W per module. If you are charging a smartphone or a tablet, note
the following:

Side USB: Up to 500mA/2.5W charging

•

Back USB: Fast charging, Supports up to 2.1A/10.5W charging
