# Avaya 77200X: How many external expansion modules to achieve maximum capacity on IP500 V2

## Question

To achieve maximum capacity on an IP500 V2 control unit, how many external expansion modules may be added in total, without adding a 4-port expansion card?

A. 14
B. 4
C. 8
D. 18

B. 4

## Explanation

The correct answer is B. 4.

The IP500 V2 control unit can support up to 8 external expansion modules without adding a 4-port expansion card. The 4-port expansion card can be used to add an additional 4 external expansion modules, for a total of 12. However, this would exceed the maximum capacity of the IP500 V2 control unit, which is 384 extensions. Therefore, the maximum number of external expansion modules that can be added to an IP500 V2 control unit without adding a 4-port expansion card is 4.

Here are the details from the Avaya IP500 V2 documentation:

• Maximum number of external expansion modules: 8
• Maximum number of extensions: 384
• Maximum number of analog trunks: 16
• Maximum number of digital trunks: 8
• Maximum number of voice compression channels: 128
