DPU Controls and Indicators
Chapter 2 provides descriptions and functional definitions of the data parallel
unit (DPU) controls. Indicators on both the outside and the inside of the DPU
show the status of the system and critical internal components.
Figure 2–1 (DECmpp 12000) and Figure 2–2 (DECmpp 12000–LC) show the
locations of the DPU front controls and indicators. To access the front controls
in either configuration, open the front door. The controls are located inside the
enclosure at the top. Figure 2–3 provides a detail of the front controls.
Figure 2–4 shows the location of the rear controls and indicators. The DPU
controls and indicators are described in detail in the following sections.
