Network Connections - Biamp Vocia VA-8150CV Mode D'emploi

Network Connections

The amplifier is a CobraNet device. A Primary and Secondary CobraNet connection is provided for this.
All CobraNet routing and bundle assignments are processed by the Vocia devices locally. Vocia makes
dynamic use of available bundles in CobraNet. A 100Base-T Ethernet switch (not repeater hub) is
required when networking multiple units. CobraNet utilizes standard CAT5, CAT5e, CAT6, or CAT7
cabling, which has a specified maximum length of 328 feet (100 meters). Additional Ethernet switches, or
switches which provide fiber-optic interface, can be used to extend the physical distance between units
within a network. Please note that CobraNet limits network extensions to seven hops (one-way
transmissions) within a network. The CobraNet network connection is configured with the primary
connector on the left and the secondary (redundant) connector on the right. The primary and secondary
CobraNet ports are provided to facilitate connection redundancy. Each connector provides two LEDs that
indicate Ethernet link and network activity.

Device ID Switches
The VA-8150CV and VA-4300CV units represent separate Vocia device types.
The rotary ID switches give the unit a unique Device ID. The switches are in hexadecimal format. All units
of the same device type must have a unique Device ID to function properly within a Vocia Paging World.
The Factory Default Device ID is 01. A Device ID of 00 is invalid and cannot be used.
To assign a Device ID of hex 07, leave the MSB switch on 0 and turn the LSB switch to 7. Device ID
switches should be set using a 0.1 inch (2.5mm) to 0.12 inch (3.0mm) flat blade screwdriver.
Changes made to the Device ID while connected to the network require a power cycle of the device in order to take effect.
Device-to-Device Failover
All amplifiers support Device-to-Device amplifier chassis failover in case of fault. The redundant amplifier
must be the same model as the primary amplifier. A Failover Link Cable must be connected between the
primary and the redundant amplifier as shown below. Connect ground to ground and Pin 1 of the primary
amplifier to Pin 2 of the redundant amplifier; connect Pin 2 of the primary amplifier to Pin 1 of the
redundant amplifier
Page Active Relay
Via the Page Active Relay connectors, one Form A (single pole, changeover) relay is presented per
channel on the VA-8150CV. Similarly, two such relays per channel are presented for the VA-4300CV
(relays operate in tandem) Each PAR connector is an eight way 3.5mm pluggable screw terminal block.
The Page Active relay connections are labeled as follows:

C – Relay Common.

NO – Normally Open.
No Data Connectivity or CobraNet activity
Link established
Link established and CobraNet activity detected; The unit is acting as a CobraNet Performer
CobraNet fault. Check cabling and configuration for errors
