Introducing Your 4620/4620SW/4621SW IP Telephone

About the Feature Key Expansion Unit (EU24/EU24BL)

The Feature Key Expansion Unit is an optional device that can be connected to your 4620 IP
Telephone. The EU24 and EU24BL contain 24 buttons onto which your System Administrator
sets up additional IP telephone features and/or call appearances (incoming and outgoing lines).
The EU24BL is essentially the same as an EU24, except with a backlit display. When we use
the term "EU24" anywhere in this guide, the information also applies to the EU24BL, unless
otherwise noted.
The EU24 is recommended for use with the 4620 and 4620SW IP Telephones. The EU24BL is
recommended for use with the 4621SW IP Telephone.
For usage instructions, see the EU24/EU24BL Expansion Module User Guide (Document
Number 555-250-702, available at http://www.avaya.com/support).
