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. The power inputs are to the right and left rear of the IMACS-200, and labeled accordingly. In Figure 1-2,the supply inputs are seen on the sides of the rear panel.

Notes:

1.The two -48VDC and 125VDC feeds are located in the lower-left and lower-right hand corners of the IMACS-200 rear panel. Based on ordering options, these ports will arrive at the customer site with screw-down terminals contained in an accessory bag in the IMACS-200 packaging. For customers who order the single-supply option, the right-hand connector above (nearest the T1/E1 and ground screw) should be used. These three-pin terminals (if so equipped) are labelled left-to-right as NC (No Connection), -48 or 125 as the case may be, and RTN (return).

2.The two 120VAC and 220VAC feeds are located in the upper-left and upper-right hand corners of the IMACS-200 rear panel. Based on ordering options, these ports will arrive at the customer site with AC jacks installed. Simply place a North-American AC power supply cord into the supplied jacks.

3.The IMACS-200 comes with two fan units installed in the unit. These fans will turn on and off automatically as the temperature fluctuates inside the enclosure. These fans are not field serviceable, and will alarm should one of them fail or become obstructed.

A more detailed description of this chassis and its power capabilities is given in chapter 3.
