The following are the typical components of a IP Office Essential Edition or IP Office Preferred Edition mode system based on an IP500 V2/V2A control unit.

|
•IP Office IP500 V2/V2A System Unit
The control unit holds the main configuration and performs the routing and switching for telephone calls and data traffic. Each control unit includes 4 slots for optional base cards to support trunk and phone extension ports.
• Avaya System SD Card
This card holds the firmware and other files used by the system. An Avaya System SD card is mandatory for system operation.
•The card's unique ID number is used for license validation.
•The card also provides storage for Embedded Voicemail if used. |
|
•License Keys
Various features and applications require licenses in the system's configuration. These are entered by uploading a single PLDS XML file containing all the system's license. The file and its licenses are specific to the ID number of the System SD card installed in the system. |

|
•External Expansion Modules
Additional ports can be added using a number of external expansion modules.
•Systems support up to 8 external expansion modules as standard. If fitted with an IP500 4-Port Expansion Base Card, up to 12 external expansion modules are supported. |

|
•Power Supplies
The IP500 control unit has an internal power supply unit. Each external expansion module is supplied with an external power supply unit. Additional power supply units may also be required for IP phones and some phone add-ons. |
|
•Power Cords
Depending on the locale, different power cords need to be ordered for each control unit, external expansion module and any phones or devices using external power supply units. |

|
•Cables
The system is designed primarily for connection to a structured cabling system using CAT3 UTP cabling. This approach allows telephone and data traffic to share the same wiring infrastructure and simplifies equipment moves. |

|
•Mounting Kits
The control unit can be used free-standing, with external expansion modules stacked above it. With optional rack mounting kits, the control unit and external expansion modules can also be rack mounted. Alternatively with an optional wall mounting kit the IP500 control unit can be wall mounted. IP500 external expansion modules can also be wall mounted. |

|
•Surge Protectors and Barrier Boxes
Where the installation includes extensions in other buildings additional protective equipment is required. This equipment may also be required in areas where the lightning risk is high. |
|
•Phones
IP Office systems support a variety of Avaya digital and IP phones plus analog phones. |

|
•Application Software/DVDs
The IP Office applications can be ordered on a number of DVDs. In addition they can be downloaded from the IP Office section of the Avaya support web site (http://support.avaya.com). |
