Figure 11 Magnetek BBU Numbering Scheme
Controller Node Numbering
The T-Class Storage System contain two, four, six, or eight controller nodes per system and only
use T-Class controller nodes. Controller nodes are loaded into the backplane enclosure from bottom
to top.
Therefore, for the T800 with only two controller nodes installed, those controller nodes would
occupy the lowest 4U of the backplane and would be numbered, node 6 and node 7. The other
bays in the backplane enclosure would be protected with filler panels that block insertion of other
components.
A controller node takes on the number of the bay that it occupies in the backplane, as shown in
Figure 12 (page 17).
