Description
The VT808 is a four-slot chassis that accommodates four x16 PCIe style modules.
Power Supplies
The VT808 can accept up to four power supplies that can provide 2+2 redundancy. The VT808 has a Power Entry Module (PEM) that manages power to each slot. The VT808 has options for Universal AC, +28V DC and +48V DC power supplies.
Cooling
The VT808 has an intelligent fan controller and the cooling is front to back.
Routing between modules
The VT808 chassis provides x4 lanes to each slot as a full mesh as data plane as well as an x1 lane full-mesh between each slot for control plane.
Integrated GbE Switch
The VT808 has a GbE Switch on board that allows each of the PCIe modules to connect via a cable or use the 16th SERDES on the PCIe Edge to connect to the switch as 1000Base-BX.
Integrated BMC
The VT808 has a health management controller on board which follows the IPMI specification. This allows dynamic cooling of the chassis as well as provide health management to the upper protocol.
Integrated USB HUB
The VT808 has a USB Hub on board that allows each module to connect via cable to the hub.
Integrated JTAG Switch Module (JSM)
The VT808 has a JSM to allow all four slots to be managed thru a single JTAG connector or via GbE using a Virtual Probe functionality.
Chassis Locator
Each chassis could be assigned a unique Chassis Locator (CL) to uniquely identify the chassis among multiple chassis within the larger system.
