1.2 System overview The AR200 is a 2U RAID subsystem in a 2U chassis and configured on the DA3100 RAID controller. The controller includes four channels that allow several hard disk configurations to provide more than 365GB storage capacity while keeping optimal fault tolerance and performance. The system supports RAID 0, 1, 3, 5, 0+1, and JBOD protocols, and comes with a comprehensive LCD panel information for easy configuration. 1.2.
1.2.3 Internal features When you remove the top cover of the chassis, you will see the preinstalled components of the RAID system. Refer to “Chapter 2 Hardware Setup” for instructions on removing and installing the top cover of the chassis. Rear panel 10 1 2 9 3 4 8 Front panel 5 1. PCI cage* 2.

When a hard drive is installed, the specific LED for that hard drive is ON (steady green) under normal conditions. If there is a problem, the LED may turn to a steady amber.
1.4 DA3100 RAID controller The front panel of the DA3100 RAID controller consists of an LCD display, status LEDs, and navigation buttons that allow you full access to system information and complete control of the RAID operation.

This chapter describes the internal hardware components and provides the procedures for installing and removing hard disk drives. The SCSI cable connections is also described and illustrated in this chapter.
2.1 Removing the chassis cover The AR200 chassis is a 2U form factor designed for easy assembly and disassembly, making the installation of internal components very convenient. At the top of the chassis is a rotating lock that secures the cover to the chassis. Unlocking the Cover To unlock the cover, turn the rotating lock clockwise until the triangle mark points to OPEN.
2.2 Installing SCSI hard disk drives The RAID system comes with six externally accessible hard disk drive bays. Hot-Swap Drive Tray On each of the HDD bays is a hotswap tray for mounting a hard disk drive. Flip open the tray levers to release the tray, then slide the tray out of the chassis. Tray Levers Take note of the drive tray orientation before you slide it out. The tray will not fit back into the bay if you insert it the wrong way.
2.3 Cooling system The chassis includes an 8-cm system fan located at the front end of the PCI cage, and a 12-cm system blower (underneath a metal hood) located between the PCI cage and the power supply. The metal hood is held in place by two tabs (one on each side) that rest on the edge of the PCI cage and power supply, and two hooks attached to the rear panel. To remove the 12-cm system blower: 1. Disconnect the fan cable from the connector (labeled FAN1) on the power interface board. 2.
2.4 SCSI backplane boards The system includes two SCSI backplane boards to support up to six Ultra160 SCA SCSI hard disk drives. The backplane design incorporates a hot-swap feature to allow easy connection or removal of SCSI hard disks. Front side The front side of a backplane has three 80-pin connectors available for SCA SCSI hard disk drives. The hard disks are externally accessible from the system front panel.
2.5 System interface board The system interface board interconnects the backplane boards, power supply, cooling fans, and the DA3100 controller. Refer to the illustration below for the specific cables connected to the interface board. All the cables are already connected when you receive the system. You do not need to disconnect the cables when installing drives or creating a RAID configuration.
2.6 DA3100 connectors Inside the DA3100 RAID controller are connectors that connect to other system components using interface and power cables. Refer to the illustration below for the specific cable connections. All the cables are already connected when you receive the system. You do not need to disconnect the cables when installing drives or creating a RAID configuration.
2.7 Power supply 2.7.1 Power cable connections The AR200 power supply unit (PSU) consists of two redundant power supply modules with five power plugs. The picture below indicates where you need to connect the PSU power plugs.
