3-2 Components

Chassis

The SC118G chassis includes six 2.5" hard drive bays and options for peripheral
drives. For the latest options, visit our Web site at: http://www.supermicro.com.
This chassis accepts a 1U backplane, up to eight fans and a power supply. SC118G
models come in black.

Backplane

Each SC118G chassis comes with a 1U backplane. The backplane will accept SAS/
SATA. For more information regarding compatible backplanes, view the appendices
found at the end of this manual. In addition, visit our Web site for the latest informa-
tion: http://www.supermicro.com.

Fans

The SC118G chassis accepts up to eight system fans. System fans for SC118G
chassis are powered from the serverboard. These fans are 1U high and are powered
by 4-pin connectors.
