If this is the last task you are doing inside the chassis, slide the power supply
module(s) back into place and replace the top front cover.

Installing a Hardware RAID Module
Hard disk drives are not supported on the CG2100 server by default. One of two
separately-orderable controller options is required. Hardware RAID support requires a
SAS/SATA hardware RAID module, which is described in this section. If basic, non-RAID
support is all that your solution requires, then the SAS/SATA control module is
adequate. See Section 4.3, “Installing a SAS/SATA Control Module“, if basic support is
what you want.
Figure 36 shows the SAS/SATA hardware RAID module, which provides SAS/SATA RAID
functionality for the server using an LSI Logic LSISAS1078* hardware RAID controller
(“B”). The module’s interface to the baseboard is through a PCI Express bus flex
circuit cable (“A”) to the bridge board. The SAS/SATA hardware RAID module is located
in the front left of the chassis between the power supply system and the SAS/SATA
backplane board. The module’s gold edge connector (“C”) mates with the SAS/SATA
backplane board.
Figure 36. SAS/SATA Hardware RAID Module
Before you can install the SAS/SATA hardware RAID module, you need to slide the power
supply module(s) out a bit for easy access to the module bracket. There is also a
protective sheet metal bracket that will hold the SAS/SATA hardware RAID module and
this has to come off also before the module can be installed.
