For each InServ E-Class Storage Server 2M cabinet, four Power Distribution Units (PDUs) occupy

the lowest chassis bay in the cabinet. For each 1M cabinet, two PDUs occupy the lowest chassis

bay. Refer to Figure 5-3 for bay numbering.

Numbers for PDUs are assigned:

■ beginning with 0.

■ from top to bottom.
