About DAE2 Disk Enclosures
Figure 1-3 Disk Enclosure Rear View
As shown in Figure 1-3 and Figure 1-4, an enclosure address (EA)
switch/indicator is located between the power supplies at the rear of
the disk enclosure. (The EA is sometimes referred to as an enclosure
ID.) Each link control card (LCC) includes a loop (bus) identification
indicator. The storage processor initializes loop ID when the
operating system loads.
