Figure 1-3Disk 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.
