Echo 2 Mbps Multiplexer
BEFORE INSTALLATION, PLEASE REFER TO THE SAFETY WARNINGS IN
APPENDIX A, APPROVALS REQUIREMENTS IN APPENDIX B, and EMC
REQUIREMENTS IN APPENDIX C
Supply Voltage & Connection
The Echo may be optionally DC or AC powered. The AC power supply is a switched mode
unit, the optional DC power supply unit being a DC to DC converter. Both allow
considerable input voltage variation.

Environmental Considerations

The Echo Multiplexer must be operated under the following atmospheric conditions:
Temperature: 0 to 40 degrees centigrade.
Humidity:
Air Pressure: 86 to 106 kPa.

Mechanical Construction

The Echo is housed in a 1.5U tall 19" enclosure. An optional rack mount kit is available on
request. Four LEDs on the front panel indicate the current status of the multiplexer.
The multiplexer MUST be disconnected from the power supply before opening the unit
or changing any network connections.
Screws on the left, right and top of the enclosure are removed using a Posidrive screwdriver
to access the interior. This allows installation of option cards.
The rear panel (illustrated on page 36) accommodates the link interface connectors and
supervisor port.
