Figure 1-5 Disk enclosure bus and address indicators
The enclosure address is set at installation. Disk module IDs are numbered
left to right (looking at the front of the unit) and are contiguous throughout
an array: enclosure 0 contains modules 0-14; enclosure 1 contains modules
15-29; enclosure 2 includes 30-44, and so on through eight enclosures.
The enclosure EA switch and bus indicator are described in the
installation procedure in Chapter 2. The status lights are described in
the “Monitoring disk enclosure status” section of Chapter 3.
Midplane
A midplane between the disk modules and the LCC and
power/cooling modules distributes power and signals to all
components in the enclosure. LCCs, power/cooling modules, and
disk drives — the enclosure’s field-replaceable units (FRUs) — plug
directly into the midplane.
Front bezel
The front bezel, shown in Figure 1-6, has a locking latch and an
electromagnetic interference (EMI) shield. You must remove the bezel
