VA-8600 Rear
AC Power Socket
Provides for connection of the appropriate power cord. Each amplifier uses a switch mode power supply
that has an operating voltage of 100-240V at 50/60 Hz. (5.5 to 2.3 Amps)
CAUTION
Do not remove or defeat the ground prong on the power cord, as this will constitute a shock hazard. Equipment should be
connected to a mains socket outlet with a protective earthing connection. This plug is the main disconnecting device and should
remain readily operable. There are no user interchangeable parts. Please contact Biamp Technical Support or your local distributor
for all service requirements.
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 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.
NOTE
Changes made to the Device ID while connected to the network require a power cycle of the device in order to take effect.
Network Module (NM-1)
NM-1 is the Network Module that is included with VA-8600 and VA-8600c. This module provides
connectivity for control and audio via the dual CobraNet interface and logic ports for the device failover
functionality. The RJ45 connector labeled "Ethernet" is not used at this time.
Reset Button
Reset button, when held down for 5 seconds, performs a chassis restart. The Status indicator will flash
yellow during restart and will turn solid green once the process is complete.
