Cisco Network Interface Module - Expansion module - 1000Base-X x 4 - for P/N: C8300-1N1S-6T C8300-1N1S-6T

The C-NIM-4X is a next-generation 1G/10G LAN/WAN module with local Layer 2 switching capabilities on all four ports. This provides a cost-effective, low-density 4-port Layer 2 LAN switch with the capacity for switching four small form-factor pluggable (SFP)/SFP+ ports at speeds up to 10 Gbps. The two highest-numbered ports can be configured for native Layer 3 operation, providing full feature parity with the router’s embedded WAN ports. This module offers high-speed WAN connectivity through four ports supporting serial gigabit media-independent interface (SGMII)/1000BASE-X-based SFP and 10GBASE-R-based SFP+ pluggables. A 100-Mbps optic pluggable connection can also be supported by using the GLC-GE-100FX SFP transceiver. The four 1G/10G WAN ports are connected to the backplane using a single 10-Gbps-capable internal link. When used at maximum capacity, they form what is known as an oversubscribed connection of 4 to 1. IEEE 802.1AE MACsec is supported as described in the product overview.
