TesiraCONNECT

tesiraconnect-crop.pngThe TesiraCONNECT TC-5 is a 5-port AVB-capable network switch designed specifically for Biamp conferencing products. The TesiraCONNECT is placed at the center of any Biamp conference room to provide power and media streaming for Biamp components. TesiraCONNECT works out of the box with Biamp products, simplifying conference room deployments and avoiding additional setup steps required in traditional media switches. TesiraCONNECT also connects multiple AVB enabled DSPs within a system. Supported topologies include the connection of up to 4 TesiraCONNECT devices in a single media network cluster. 

Capabilities and limits

TesiraCONNECT is a Tesira infrastructure device that runs Tesira Firmware 3.12 and later. All configuration, firmware updates, and fault monitoring are provided via Tesira Software and Biamp SageVue. TesiraCONNECT is primarily intended for use with Tesira devices.

  • 5-ports with 100/1000M Ethernet
  • All 5 ports are AVB enabled with support for up to 150 AVB streams
  • 4 ports provide PoE+ Class 4 with 120W budget
  • RSTP (rapid spanning tree) Support
  • Supported topology is up to 4 TesiraCONNECT devices in a single media network cluster 
  • Standard Ethernet distance limits using Cat 5e UTP or better
  • Universal external power supply
  • Only Biamp conferencing equipment is supported

Larger topologies, TesiraLUX video streaming, third-party AVB devices, and mixed AV protocol networks require the use of Avnu-certified interoperable switches. Please see the List of AVB-capable Ethernet switches for further information.

Installation

TesiraCONNECT may be mounted under table with the optional mounting bracket, behind a display, in a credenza, a plenum space, or anywhere that it is convenient to accommodate a room design. 

TesiraCONNECT TC-5 uses a fanless design and is passively cooled. Ensure adequate airflow around the device and that the ambient temperature remains between 0°C to 40°C. Excessive ambient air temperature or blocked airflow may result in overheating. TesiraCONNECT will provide fault alerts if over temperature. 

Connection

Up to four TesiraCONNECT TC-5 devices can be used within a single media network cluster. The devices may be in a star or chain topology. The TesiraCONNECT is intended to connect to the AVB port of a DSP and provide connectivity for expander devices in a room. Tesira supported network topologies must be observed.

All 5 ports of the TC-5 are AVB enabled. Ports 2-5 provide PoE+ power. The DSP should be connected to Port 1. Any powered expander devices, additional server-class devices, or additional TC-5 devices should be connected to ports 2-5. 

The following diagram shows a chain topology connection.

The following diagram shows an example star topology connection:

Single network connection

Tesira devices support converging control and AVB media on to a single network cable. Multiple DSPs may be connected to a TesiraCONNECT using single cable mode. Single network connection supported topologies must be followed. The TesiraCONNECT would need to be directly attached to a control computer or uplinked to a control network when using single network connection on the DSPs, to allow a computer to connect to the system via Tesira software. TesiraCONNECT does not support mixing separated and single cable connections within the same system, and it does not provide router functions between isolated control and media networks.

Setup

Under most use cases, the TesiraCONNECT TC-5 requires no configuration out of the box to power Biamp conferencing equipment. TesiraCONNECT does not compile into in a system configuration and does not require any Equipment Table assignment. It does not count against Tesira system device limits or expander proxy limits. Like any Tesira device, all configuration of TesiraCONNECT is managed via Tesira software and Biamp SageVue software. 

Device discovery

The TesiraCONNECT device is discoverable in the Device Maintenance window of Tesira Software. Configuration and firmware updates for the device are performed from this window.

The TesiraFORTE or SERVER-IO in the system will facilitate discovery and control communication between the Control and AVB networks for the TesiraCONNECT device. This requires that separated networks are enabled on the DSP, which is the default in Tesira 3.8 and newer. If separated networks is not enabled or both the AVB and Control networks of the DSP have the same subnet, the TesiraCONNECT device will not be discoverable. 

Network settings

TesiraCONNECT offers the same network settings as any other Tesira server-class device. The network settings are accessed via the Device Maintenance window.

The hostname, network addressing and device services are modified on the Control Network tab.  

By default, RSTP is enabled and the control IP address is obtained automatically. The Tesira media network generally will run without a DHCP server and default to a link local IP address. 

Telnet and SSH are provided for TTP (Tesira Text Protocol) and are disabled by default. Since the TesiraCONNECT is not part of a system configuration, TTP is limited to DEVICE and SESSION commands only. 

The AVB tab provides the peer delay setting. The value should be increased if using fiber media convertors because they add more latency to the link. 

Firmware update

TesiraCONNECT is part of the Tesira platform and is updated using Tesira Firmware TFA2 files. Tesira firmware version 3.12 or newer is required.

All Tesira devices may be updated at the same time as TesiraCONNECT. When a TesiraCONNECT device and Tesira server-class device are both selected, the TesiraCONENCT devices are updated first. The update progress window will display "Pending" on the DSP until the TesiraCONNECT devices have finished. 

Locate devices

TesiraCONNECT supports the Locate function. All LEDs on the front of panel of the TesiraCONNECT will flash green when locate is active. The network port LEDs do not flash for locate.

Status LEDs and fault reporting

Status LEDs

The following states are represented on the front panel LEDs of the TesiraCONNECT device.

LED Off Green Flashing Green Yellow Red Alternating Red/Yellow
Alarm No alarm condition present Not Applicable Unit is in Locate mode Unit has minor alarm condition present Unit has major alarm condition present Unit has minor and major alarm condition present
Per-Port LED No Ethernet link Ethernet link active/up Unit is in Locate mode Not Applicable Not Applicable Not Applicable
Power No power supplied Device is powered Unit is in Locate mode Unit is booting Not Applicable Not Applicable
RJ-45 Ports No Ethernet link Ethernet link active/up Data activity Not Applicable Not Applicable Not Applicable
Status No power supplied Unit is fully booted and ready Unit is in Locate mode Unit is booting Not Applicable Not Applicable
Faults

The following major and minor faults are reported by TesiraCONNECT.

Alarm Level Fault Message Comment
None N/A Normal operation.
Minor Over temperature warning CPU has exceeded 75 °C. Ensure ambient is under 40 °C and adequate ventilation around device.
Major PoE+ fault on port #, Over current limit May indicate issue with network cabling or powered end-point device.
Major AVB bandwidth exceeded Stream reservation limit exceeded, check uplink bandwidth. 
Major Over temperature fault CPU has exceeded 81 °C. Device operation is unstable past 85 °C.

The front panel provides a fault LED. Tesira Software and Biamp SageVue will report fault messages. Additionally, any Tesira server-class device will report a fault if a discovered TesiraCONNECT device has an alarm. The DSP will report "Infrastructure device <hostname> fault detected".
