Mounting Details

The unit is designed to be mounted within a 2000 or 2005 Subrack on standard card guides. Note the
AMG standard racks are supplied with guide rails every 7HP. In order to fit this unit in the subrack, 1
set of card guides have to be removed by pulling gently on the card guides.

The 2000 series subrack is fitted with a 50 watt power supply. A maximum of 4 units may be fitted into
one 2000 series subrack.

The 2005 series subrack is fitted with a 100 watt power supply. A maximum of 5 units may be fitted
into one 2005 series subrack limited by the 70HP rack space.

Data and Audio Channel Configuration and Connection

The AMG2648R has a capacity for 4 bi-directional data and 4 bi-directional audio channels. For these
channels to be present, appropriate data daughter boards have to be fitted onto the main data
motherboard.

Data and Audio Channel Configuration

The data and audio daughter board’s slots are accessed by removing the 2600 unit from the case.
(See below for

removal from the case

).

In order to enable a data channel an appropriate daughter board should be fitted in the upper data
channel slots on the main data motherboard. Each data interface board enables one bi-directional
channel. The data interface daughter board options are as follows:
