    Installation Procedures A30808-X5130-BllO-l-8928 
    Issue 1. May 1988 
    SECTION 2.00 EQUIPMENT LOCATION AND IDENTIFICATION 
    2.01 General. The SATURN IIE System is housed in a sin- 
    gle, lightweight equipment cabinet with expansion capabili- 
    ties. An LTU shelf can be added within the basic cabinet: in 
    addition an expansion cabinet which contains one or two LTU 
    shelves can be mounted on top of the basic cabinet. Figures 
    2.00 and 2.01 show the basic cabinet and expansion cabi- 
    net. The block diagram shown in Figure 2.02 identifies the 
    functional blocks of circuits into which the system is divided. 
    These functional blocks are related to the system hardware 
    groups. for expansion. The expansion cabinet can contain one 
    or two LTU shelves. 
    b. Power and Distribution Equipment. The SATURN IIE 
    System makes use of distributed power in the cabinet. 
    Several power modules of various sizes are located 
    alongside and at the bottom of the system cabinet. For
