3. The Hardware

This chapter describes the A__UHD Core hardware.

3.1 Overview

The A__UHD Core is an IP-based processing core.

Each A__UHD Core supports up to 1024 processing channels. These can be dedicated to a single console or

shared between up to four systems. The amount of resource available, and whether sharing is possible, is

determined by the A__UHD Core license. A second device can be installed to provide DSP redundancy.

The A__UHD Core streaming connections are established using RAVENNA. The streams are fully compatible

with the SMPTE ST2110-30/31, AES67 and RAVENNA standards. Redundant streaming can be configured via

SMPTE ST2022-7 Seamless Protection Switching.

The A__UHD Core is designed for 1RU, 19" rack-mounting. The device is fitted with dual-redundant power

supplies.

3. The Hardware

3.2 Controls, Connectors & Indicators

3.2.1 Front View

1 SYSTEM Display

The display shows the Management A IP address. In the current release, the rotary control has no function.

2 STATUS LED

This LED indicates the health of the device. If the LED is blinking at regular intervals, then the device is working

properly.

3 DONGLE

Use this port to connect the USB memory stick containing your system's WIBU license. The port is protected

by a cover plate to prevent accidental removal of the dongle. To remove the cover, you will need a T10 star tool.

4 MGMT A & B - Management Network

The two Management Network ports provide a connection to the device's control system (for administration and

control).

5 USB

The USB port can be used for service procedures

6 SERVICE panel

This area is protected by a cover plate. To remove the cover, you will need a T10 star tool. Once removed, you

will find the following ports/buttons:

USB-A and Display Port - for a local KVM connection.

USB-B - for debugging.

RESETbutton - press to perform a warm start.

A warm start will reboot the device. Do NOT perform a warm start while live on air!

7 IO 1 to 8 (via SFP) - Media Network

The eight 10/1 GbE network IO ports stream audio to and from an IP network.

The streams are fully compatible with the SMPTE ST2110-30/31, AES67 and RAVENNA standards. To achieve

redundant streaming compatible with SMPTE ST2022-7, you must connect odd/even port pairs to discrete

network paths. The Media Network must be properly managed and configured.

The LED beside each port indicates the status of the network connection: green, flashing = link up + network

traffic; green, static = link up, no traffic; off = link down.

8 Ventilation Holes

Internally, the device is fitted with slow turning, lownoise fans which are temperature controlled. Ventilation holes

are provided at the front and rear of the unit.

Take care that no devices or cables obstruct the flowof air and, thereby, hinder cooling.

3. The Hardware

3.2.2 Rear View

9 10101 - Serial Port

The serial port can be used for debugging.

10 WCLK IN, THRU & OUT

The wordclock ports can be used for external synchronization.

11 MAINS 1 & 2

The MAINS 1 & MAINS 2 connectors supply AC mains power to the frame. The sticker below the connector

states the AC mains requirements.

Only one PSUis required for the system to operate; the second provides redundancy.

The DC OK LEDs indicate the status of each PSU: green, static = the power supply is working properly; off

(unlit) = there is no power or low DC voltage (to the main circuit board).

12 CASE

The CASE grounding screw should be used to ground the frame.

4. Installation

This chapter describes how to install the hardware.

4.1 Unpacking

A__UHD Core is delivered in its own box with all included accessories. If you have ordered SFP modules then

these will be delivered separately.

Please check the contents of the shipping boxes, and in the event of any transport damage, contact your local

Lawo representative or email support@lawo.com.

4.2 Packing List

Included

The following items are included with each A__UHD Core:

2 x 2m IEC power cables (country-specific) - to connect mains power to the frame.

1 x USB license dongle (250-5998-000).

1 x 75Ω terminating resistor (designed as BNC connector) - to terminate the Wordclock THRU port.

Dust caps for the SFP cages - these will be mounted in the frame.

Note that you will need to install your A__UHD Core license onto the USB dongle before connecting it to the

device. The license code for your chosen feature set can be found on the delivery note.

Optional

The following items must be ordered separately.

SFP modules - for the Media Network IO ports. You must order one SFP for each port you wish to use.

4. Installation

4.3 Mounting the Frame

Recessed Rack

Adapters

A__UHD Core is designed to be mounted in a 19-inch rack. Please install supporting slide bars to hold the weight

of the unit, and use the locking devices provided. For recessed rack-mounting, use standard, third-party, 1RU

recessed rack adapters such as the ones shown above. When fitting the rack adapters, you must make sure that

there is sufficient airflow around the device for cooling.

Connectors are located at the front and rear of the unit. Therefore, when using 19-inch racks with doors please

leave enough room for the cables.

4.4 Dimensions and Weight

Width

483 mm (19”)

Height

44.0 mm (1 RU)

Depth (inc PSU)

379 mm

Weight

7.4 kg

4.5 Temperature and Cooling

A__UHD Core is equipped with temperature-controlled fans for minimum noise emission. Ventilation holes are

provided at the front and rear. There must be sufficient airflow around the device for cooling.

DO NOT obstruct the ventilation holes as to do so will prevent efficient cooling.

The recommended tolerances can be found in the data sheet for the A__UHD core main frame.
