Page 25: System Overview 1.1 Introduction
System Overview Introduction Chapter 1 System Overview Introduction This chapter describes chassis used by the IMACS-200. The IMACS-200 is available with redundant power supplies which operate in a load-sharing mode. The IMACS-200 chassis is manufactured to be RoHS-compliant. The IMACS-200 comes “Industrial hardened” to operate under more extreme temperature ranges of -40 degrees Celsius to +70 degrees Celsius (-104 degrees Fahrenheit to +158 degrees Fahrenheit).
Page 26 Model No. Running Head Introduction System Overview The IMACS-200 offers a range of power input options, which are selected to be the most commonly used input voltages in use by our various customers. They are: -48VDC, 125VDC, 120VAC and 220VAC. The power supply modules are factory installed, and will come with the proper connectors configured for the IMACS-200 powering options you have selected.

Page 29: Rack Installation Tips
System Installation Chassis Installation Be sure to locate the system near all external equipment to which you will connect it. Cable lengths and physical/electrical characteristics are critical to system operation, especially for data signal interfaces. Generally, higher data rates require shorter cables than lower data rates. Also, you must use T1-grade cables for all system connections to those networks.

Page 273 Switch request sent to port. The system has sent your redundancy switchover command to the associated port. Switchover must be made from the primary WAN. You cannot switch to a redundant WAN port from another redundant WAN port. You can only switch from a primary port to a redundant port.
