Description
The EH1D2X12SSA0 is a 12-port 10GBASE-X optical interface board (SA, SFP+) in the S9700 series, providing 12 10GE SFP+ optical ports, distributed line-speed forwarding, and hot-swappable interfaces. It is compatible with S9703/S9706/S9712 chassis and is primarily designed for medium-density 10GE access/aggregation scenarios. The EH1D2X32SSC0 is a 32-port 10GBASE-X optical interface board (SC, SFP+) in the S9700 series, providing 32 10GE SFP+ optical ports, distributed line-speed forwarding, and hot-swappable interfaces. It is compatible with S9706/S9712 chassis and is primarily designed for high-density 10GE access/aggregation scenarios.
EH1D2X12SSA0: 12-port SFP+, low power consumption, lightweight, supports S9703 small chassis, suitable for medium-density 10GE, power-sensitive scenarios with limited chassis resources.
EH1D2X32SSC0: 32-port SFP+, ultra-high density, supports only S9706/S9712 large chassis, suitable for high-density 10GE, high bandwidth, and high-density access scenarios in data centers/campus cores.
Both support distributed line-speed forwarding, hot-swapping, and rich L2/L3/MPLS features, with consistent reliability.
