10.12.9 EXPANSION Port
This type of port is found on the rear of IP Office control units and external expansion modules. It is used for connecting
the external expansion modules to there parent IP Office control unit.
The connection between these ports should only be done using an Avaya Expansion Interconnect Cable. No other cable
type should be used.
•
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+.
Expansion Interconnect Cable
The Expansion Interconnect cable is used to link expansion ports between the IP Office control unit and external
expansion module (except WAN3 modules).
•
Supply: One cable is normally supplied with each external expansion module.
•
SAP Code: 1m (3'3") Blue cable - 700213457, 2m (6'6") Yellow cable - 700472871.
10.12.10 EXT O/P Port
These ports are found on the rear of all IP Office control units. They are used for connection to external switching relays.
The port uses a standard 3.5mm stereo jack plug for connection.
The IP Office is able to open (high resistance), close (low resistance) or pulse (close for 5 seconds and then open) two
switches within the port. Either switch can be operated separately. These switches are intended for activation of external
relays in systems such as door opening systems.
•
CAUTION: In installations where this port is connected to a device external to the building, connection must be via a
towerMAX SCL/8 Surge Protector and a protective ground connection must be provided on the IP Office control unit.
EXT O/P Pin Description
1 Switch 1.
2 Switch 2.
3 0 Volts (Ground/Chassis)
•
Switching Capacity: 0.7A.
•
Maximum Voltage: 55V d.c.
•
On state resistance: 0.7 ohms.
•
Short circuit current: 1A.
•
Reverse circuit current capacity: 1.4A.
•
Ensure that pins 1 and 2 are always at a positive voltage with respect to pin 3.
3.5mm stereo audio jack plugs are frequently sold as pre-wired sealed modules. It may be necessary to use a multi-
meter to determine the wiring connections from an available plug. Typically 3 (common to both relays) is the cable
screen.
