CONTROL AND MAINTENANCE PANELS

Figure 3-5.—Example of a control and maintenance panel (CMP). Power controls and indications operations, and testing the computer. Again review the Initiate computer operations controls Operations and temperature indications Battle short controls and indications The operator panel only allows for powering up/down the maintenance console and the modules within the computer’s frame or cabinet. It does not allow for powering up/down individual modules. Just like the power/temperature panel, you must become familiar with correct procedures for routine powering up/down and emergency situations. You will find these procedures in the computer’s technical or owner’s manual, system operating manuals, desktop guides, or locally generated system doctrine. The operator panel is located in the frame or cabinet above the logic chassis. The operator panel has five levels of controls and indications as follows: Power (blower, logic, and battle short) Logic power indications Overtemperature indications Initiate computer operations Monitor computer operations CONTROL AND MAINTENANCE PANELS Control and maintenance panels (CMPs) have controls for powering up/down the computer, loading and operating programs, initiating computer procedures for routine and emergency power up/down procedures. You can divide control and maintenance panels and their controls and indicators into seven physical areas. They are as follows: Ac power controls Program controls Operator interfacing (displays and keyboard) Built-in-test (BIT) controls and indicators Battle short controls and indicators Cooling fault controls and indicators Dc power controls and indicators The panel in our example (fig. 3-5) also lists some of the information that can be displayed in the Display Select or Fault. You can monitor operations using the display and indications; and you can interface (using inspect and change procedures or manual operations) with the CPU/IOC and memory using the display and keyboard. Computer monitoring capabilities during operations and maintenance include switch settings, hardware availability, halts, jump stops, and operator input. Remember that key settings can interact with computer software. This control and maintenance panel is usually located in the front of the frame/cabinet. It has six levels of controls and indications. They are as indicated: Power (primary, logic, and battle short) 3-8
