Auxiliary Power
The VA-2060e and VA-4030e support 48V DC Auxiliary power connections. The VA-2060 and VA-4030
do not support 48V DC Auxiliary power connections.
This connection allows dual DC power inputs to be used. Dual DC supply capability allows the amplifier to
meet standards that call for redundant power supplies. If an amplifier is required to operate without a DC
supply, the Auxiliary supply fault monitoring must be disabled in Vocia software. A loss of supply fault is
indicated via the Vocia software and by a blinking amber 'Amp Fault' indicator on the front panel of the
affected device. The power supplies used for the amplifier must meet the voltage range and current
requirements detailed in the specifications table. Local standards, norms or codes may require the use of
certified power supplies and may require observance of minimum 'on battery' running times both for
standby and maximum power conditions.
Due to potential energy hazard, connections to the Auxiliary Power DC inputs must be made by a qualified electrician or other

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.
CAUTION
qualified person as required to conform with all local codes.
