Product Description
The ASR 104 is a EIA310-D standard 1U chassis design that balances what is possible and what is needed. It supports most form factor server board in the market, Single Pentium 4 or Althon , Dual Intel Nocona/Irwindale or Dual AMD Opteron Server Boards in a high density and cost-effective enclosure.

The ASR 104 storage server chassis delivers technology that differentiates your company by helping you to create integrated competitive solutions that win. Your customers need it, expect it, and demand it.

The ASR series Storage server balances what the End-User and System vendor needs to deliver the best solution, provides a classy design, highest flexibility, easy to install and maintain, more storage in limited space and ultimate drive and data protection in this limited space. Each unit has up to 4 dual row hot-swappable cooling fans and with multiple temperature sensors at the hot points.

The ASR -104 backplane with built in power supply-to-drive isolation power management circuitry allows control over voltage and current fluctuations to protect the data anfd thcritical hard disk drives, making the ESR104 uniquely suitable for today's highly demanding system workloads.

Specification

SATA backplane Specification

• A power MOSFET to provide disk spin-up control 
• A pre-charge circuit for surge current protection when a disk is plugged in to protect the hard-disk drive and the backplane. 
• LED: Blue ON = HDD present; Blue Blanking = Drive activity; Red=Drive failed 
• A 4x2 header for Drive activity and Drive failed LED signal input 
• A 4x3 jumper with 4 jumper cap is added to select either disk activity LED is provide by the Host Bus Adapter or form HDD such as Western Digital or axtor Diamond Max X hard disk drive
• Single DC input to provide better cable management
• SATA data connector with latch to secure the SATA cable is not loose 8. Options included Point-to-Point or Multilane data cable connection. 32pin 4-lane-to-1-lane connection available (special order only)
