Biamp Vocia POTS-1 Manual Del Operador página 6

Power
The POTS-1 requires an external single 24V DC power source to operate, but is capable of accepting
dual 24V DC inputs for redundancy. Both power sources may be connected concurrently, however each
must be capable of supporting the full 30 watt load of the unit (inputs are not intended to load-share).
Loss or return of either power source will not result in an interruption to normal operation as long as one
of these power sources remains functional. Monitoring of power sources is selectable via the Vocia
Software.

The power connector is a four-way 5.08mm standard header with mating pluggable screw terminal block
with cable restraint. When power is present at either or both 24V power inputs the corresponding front
panel green power LED will illuminate.
Due to potential energy hazard, connections to the Auxiliary Power DC inputs must be made by a qualified electrician or other
Device ID
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.
Network Connections
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.

qualified person as required to conform with all local codes.
