The EN-8950 chassis is capable of being rack mounted when installed with the optional rack mount bracket handles and can readily fit in an industrial standard 5U-19" rack mount cabinets. The optional hot-swappable RAID module houses five SCA-2 (1" height) hard disk drives. The HDD module has a back plane for true hot-swap capability. The EN-8950 chassis is powered by a single 300W ATX PS and is cooled by two 80mm cooling fans in the rear. The state-of-the-art modular design of the EN-8950 allows it to be implemented as either a stand-alone server chassis or an integrated server-RAID chassis.
