SRB-3300H is a edge computing system and a docking station component designed for SRB-3300H scalability. The host is connected to the docking station backplane through dedicated slots, which can provide PCIe x16 Gen3 signals and a maximum power supply of 150W to the docking station. The docking station has multiple specifications to choose from, and can support 2 or 4 full height and half length PCIe or PCI expansion cards. Some models offer 2.5 "SSD expansion capabilities. The 4-slot docking station has an auxiliary power supply interface. When the power consumption of the expansion card is high and the host power supply is insufficient to support the normal operation of all cards, additional power can be provided through the auxiliary power supply interface. All docking stations have optional cooling fan components to ensure stable system operation in harsh temperature environments.
