NOTE: There are two dip switches on the IDSDM/vFlash card for write-protection. NOTE: One IDSDM card slot is dedicated for redundancy. NOTE: It is recommended to use Dell branded MicroSD cards associated with the IDSDM/vFlash configured systems. NOTE: The IDSDM and vFlash slot is not hot-pluggable. Environmental specifications NOTE: For additional information about environmental certifications, please refer to the Product Environmental Datasheet located with the Manuals & Documents on www.dell.com/poweredgemanuals Table 7. Temperature specifications Temperature Specifications Storage -40°C to 65°C (-40°F to 149°F) Continuous operation (for altitude less than 950 m or 3117 ft) 10°C to 35°C (50°F to 95°F) with no direct sunlight on the equipment. NOTE: Maximum of 205 W, 28 core processor is supported in systems with eight 2.5 inch processor direct attached PCIe SSD drives, and three PCIe slot chassis. NOTE: Certain configurations may have ambient temperature restrictions. For more information see the Ambient temperature limitations section.
