Chapter 1: Introduction
1-3 Server Chassis Features
The SC812S is Supermicro's second-generation 1U chassis and features three hard drive bays, two front side USB ports and a revolutionary cooling design that can keep today's most powerful processors running well below their temperature thresholds. The following is a general outline of the main features of the SC812S chassis.
System Power
When configured as a SuperServer 6012P-6, the SC812S chassis includes a 400W cold-swap power supply.
SCSI Subsystem
The SCSI subsystem supports three 80-pin SCA Ultra160 SCSI hard drives. (Any standard 1" drives are supported. SCA = Single Connection Attachment.) The SCSI drives are connected to an SCA backplane that provides power, bus termi- nation and configuration settings. The SCSI drives are also hot-swap units.
Control Panel
The SC812S control panel provides important system monitoring and control information. LEDs indicate power on, network activity, hard disk drive ac- tivity and system overheat conditions. Also present are a main power button, a system reset button and an NMI (non-maskable interrupt) button.
I/O Backplane
The SC812S is a 1U rackmount chassis. Its I/O backplane provides one full- height full-length and one half-height half-length PCI slots, one COM port (the other is internal), one VGA port, two USB ports, PS/2 mouse and keyboard ports and two Ethernet (LAN) ports and an external SCSI port.
