System Overview: External Expansion Modules
Connecting External Expansion Modules
The integral expansion ports on a control unit are located on the rear of the unit. For IP500 systems, an additional 4
expansion ports can be added to the front of the control unit by installing an IP500 4-Port Expansion card.
•
Each external expansion module (except the WAN3 10/100) is supplied with a blue 1 meter (3'3'') expansion
interconnect cable. This cable must be used when connecting to expansion ports on the rear of a control unit.
•
When connecting to expansion ports on an IP500 4-Port Expansion card, a yellow 2 meter (6'6") expansion
interconnect cable can be used in place of the standard blue cable. 4 Yellow cables are supplied with the IP500
4-Port Expansion card.
•
The WAN3 10/100 module differs in that it connects via a LAN port on its front to one of the control unit's LAN
ports. This type of external expansion module is not supported by IP500 control units.
•
Pre-IP Office 5.0 IP500 systems require an IP500 Upgrade Standard to Professional license to support
external expansion modules. This license is not required for IP Office 5.0+.
