CRUs addressing 2U 12-drive chassis
NOTE:
The 2U12 chassis is configurable as either an RBOD (DS4200/DS2200) or an EBOD (DS EXP).
NOTE:
shows isometric pictorial representations of controller modules and expansion
modules used in 2U 12-drive Lenovo ThinkSystem enclosures. Modules are shown oriented for insertion into IOM
slot A located on the enclosure rear panel.
