3.2.3 Confirming the delivered components of an expansion rack
An expansion rack is a dedicated rack required for connecting each SPARC M10-4S unit through a crossbar box. Dedicated power distribution units (PDUs) for supplying power, crossbar boxes, crossbar cables (optical), and XSCF cables are mounted as standard in the expansion rack.
The expansion racks are expansion rack 1 and expansion rack 2. Expansion rack 1 is used for configurations up to the 8BB configuration. Expansion rack 2 is used for the 9BB to 16BB configurations.
Figure 3-1 is a list of accessories for expansion rack 1 and expansion rack 2. Figure 3-2 is a list of connecting kit components supplied with expansion rack 2.
