5U Chassis Core Product
The 5U chassis consists of a sheet metal chassis, integrated PCBs, and a module runner system. The
design concept is based on an chassis subsystem together with a set of plug-in modules. A typical
chassis system—as supplied—includes the following:
• A chassis consisting of:
• Two sliding drawers containing Disk Drive in Carrier (DDIC) modules (42 drive slots per drawer).
• An Operator’s (Ops) panel.
• A chassis drawer bezel.
• A midplane PCB into which other components and CRUs connect.
• Two power supply units (PSUs) with power cords.
• Five cooling fans.
• Two RAID controllers (with Ethernet cable) or two expansion IOMs: 2 x SBB-compliant interface
slots.
• Up to 84 DDIC modules populated within two drawers (42 DDICs per drawer; 14 DDICs per row)
