Key features and benefits
Short-depth 2U chassis
The 297.4 mm depth suits compact racks, media cabinets and installations with substantial rear cabling.
Dual 2.5GbE connectivity
Two 2.5GbE RJ45 ports support multi-gigabit access and port trunking.
Integrated graphics and HDMI
Intel UHD Graphics, HDMI 1.4b and hardware-accelerated transcoding are included.
PCIe expansion
One PCIe Gen 3 x2 slot supports compatible network, QM2 or USB expansion cards within the stated dimensions.
QTS and QuTS hero path
The system runs QTS by default and can switch to QuTS hero starting from QTS 5.2.2.
Redundant power supplies
Two 300W power supplies support continuity-focused rack deployments.
