| 2 | -------- |
| 3 | The T4240QDS is a high-performance computing evaluation, development and test |
| 4 | platform supporting the T4240 QorIQ™ Power Architecture™ processor. T4240QDS is |
| 5 | optimized to support the high-bandwidth DDR3 memory ports, as well as the |
| 6 | highly-configurable SerDes ports. The system is lead-free and RoHS-compliant. |
