System Limits

Tesira systems can incorporate a huge number of Tesira servers, expanders, and control devices; allowing Tesira to scale from small systems to the largest systems. There are upper limits on the number of devices that can participate in a single Tesira system.

Tesira devices are categorized as follows:

Server-Class Device	Tesira Amplifiers	Remote Audio Expanders	Logic Expander	Control Device	Video Device	Infrastructure Device
SERVER	AMP-4350R	EX-IN	EX-LOGIC	TEC-1	TesiraLUX IDH-1	TesiraCONNECT TC-5
SERVER I-O	AMP-4175R	EX-OUT		HD-1	TesiraLUX OH-1	TesiraCONNECT TC-5D
TesiraFORTÉ	AMP-8175R	EX-IO		TEC-X 1000
	AMP-4300R CV	EX-AEC		TEC-X 2000
	TesiraXEL 1200	EX-MOD
	Voltera D Series	TCM-1/TCM-X
	Voltera D M Series	TCM-1A/TCM-XA
		TTM-X
		AMP-450P/AMP-450BP
		EX-UBT / EX-USB
		Lab Gruppen Amplifier
		NPX

Systems using firmware version 4.2 or newer

The following device count limits apply to all Tesira systems, running firmware release 4.2 or newer:

Up to 128 Server, Expander, Video and/or Control devices, in any combination
Up to 128 devices per network segment
Each TesiraFORTE X, Tesira SERVER and SERVER-IO can act as the proxy host for up to 64 Expander devices.
Each TesiraFORTE can act as the proxy host for up to *32 Expander devices.
Each TesiraCONNECT TC-5D, TesiraLUX, Tesira XEL, and Tesira AMP (mains powered version) can act as the proxy host for up to 64 Expander devices. Audio expanders require a Tesira processor with available network streams and DSP resources.
Each Voltera D can act as a proxy for Tesira expanders. Up to 5 expanders may be proxied from the 4 channel models and up to 9 on the 8 channel versions. A small amount of available DSP overhead in Voltera D allows for input/output expansion and routing even in systems where Votlera D is the only Tesira server class device.

*Each Tesira SERVER, SERVER-IO and TesiraFORTE can act as the proxy for up to 16 NPX Expander devices.

Tesira systems with only Video and Control devices

For systems containing only Video devices, Control devices and/or Logic expanders, the following device count limits apply:

Up to 128 Video devices, Control devices and/or Logic expanders.
Each Video device can proxy up to 64 Logic expanders.

AVB Expanders cannot participate in a video-only system. For installations that require more than the device limits allow, the system will need to be split in two or more independent systems on isolated network segments.

TesiraCONNECT

TC-5

TC-5 is an AVB capable PoE+ device designed for use in Tesira conference systems to connect Tesira devices.

The TC-5 is unique in the Tesira family of devices:

TC-5 will not show up in the equipment table.
TC-5 units are not part of a system and will not show up in a system view dialog when Tesira software is connected to a system.
TC-5 units will show up in Device Maintenance as a Server device with certain exceptions.
TC-5 devices do not count against the total device count in any system.

TC-5D

TC-5D is a Dante and AVB capable PoE+ device designed for use in conference systems to connect Biamp and Dante devices.
