In this chapter, you are shown how to install your DCS9550 1S1 Storage Expansion Unit and plug-in modules into an industry standard 19 inch rack cabinet. Caution Planning Your Installation Before you begin installation you should become familiar with the configuration requirements of your DCS9550 1S1 Storage Expansion Unit, detailed in Table 2–1.
1 x 4 bay module would take the space of 1 drive width by 4 drive bays high (in the rack mount configuration). The DCS9550 1S1 Storage Expansion Unit is housed in a 4 x 4 enclosure, that is, 4 bays wide by 4 bays high.
DCS9550 1S1 Storage Expansion Unit may be installed without loss of space within the rack. Use of other mounting hardware may cause some loss of rack space.
Handle the module carefully and avoid damaging the connector pins. Do not install the module if any pins appear to be bent. IBM System Storage DCS9550 1S1 Storage Expansion Unit Installation, Service, and User Guide...
