Chapter 1: Introduction
Onboard Controllers/Ports
The color-coded I/O ports include two COM ports (one header and one port), a VGA (monitor) port, Seven USB 2.0 ports (2x rear, 4x header, 1x type A), PS/2 mouse and keyboard ports, two gigabit Ethernet ports and one dedicated IPMI LAN port.
Graphics Controller
The H8DGU-F features an integrated Matrox G200eW graphics chip, which includes 16 MB of DDR2 memory.
Other Features
Other onboard features that promote system health include onboard voltage monitors, auto-switching voltage regulators, chassis and CPU overheat sensors, virus protection and BIOS rescue.
1-3 Server Chassis Features
The 2022G-URF is built upon the SC825TQ-R720UB chassis. Details on the chassis and on servicing procedures can be found in Chapter 6. The following is a general outline of the main features of the chassis.
System Power
The SC825TQ-R720UB features a redundant 720W power supply consisting of two power modules. The system does not need to be shut down when replacing or removing a single power supply module.
Hard Drive Subsystem
The SC825TQ-R720UB chassis was designed to support eight hot-swap SATA or SAS hard drives. (Requires UIO controller card - not included with system.)
Note: A SAS or SATA UIO card must be installed to support SAS or SATA drives.
PCI Expansion Slots
A riser card (RSC-R2UU-UA3E8+) on the left side of the chassis can support a AOC-PG-i2+ add-on card to provide two additional Gb LAN ports. Alternately, this slot can instead support either a UIO card, one PCI-E x16 card, or four SAS/SATA drives with an optional UIO SAS card. See our web site for details (http://www. supermicro.com/products/nfo/UIO.cfm). See section 5-6 for further details.)
