The RS235 (rugged 2U server with short depth) offers extended capability with shock/vibe rating of 4.43 G_RMS in combined wheeled vehicle and aircraft profiles, a temperature range of –40^oC up to 71^oC (-40 to160^oF) and multiple power options. The RS235 is available with the following processor: Socket 1366 ( Intel Nehalem-EP & Westmere-EX) CPU. Expansion capabilities in this short depth (20 inches) rugged server include One (1) PCIe 2.0 x16 (x8 signals) Slot, One (1) PCIe 2.0 x8 Slot, and One (1) PCI Slot, meaning greater adaptability. Up to ten drives and a slimline CD/DVD are available. The drives are removable and hot swappable.

All Crystal products are designed and being tested to meet MIL-STDs 810F, 167-1, 461E, and 901D requirements. As always, each Crystal product comes with a standard three-year warranty. On-site, next day and extended warranties are available. Configuration Management is also available upon request.

* Crystal Group designs all servers to meet or exceed the specifications listed herein. Due to the sheer number of models and combinations of components (memory, CPU, peripheral cards, hard drives), it is not practical to test every combination of servers offered. Please ask your Crystal Business Development Manager for data on qualification testing for configurations similar to the desired configuration for your application.
