Cisco WS-X6704-10GE-3BXL 4-Port 10GE Network Module

Cisco WS-X6704-10GE-3BXL is a Catalyst 6500 Series 4-Port 10-Gigabit Ethernet Module that combines the base WS-X6704-10GE module with a Distributed Forwarding Card 3BXL (DFC3BXL) to provide four independent 10Gbps Ethernet ports for high-speed uplinks within a Catalyst 6500 chassis. Each port supports 10-Gigabit Ethernet in both full- and half-duplex modes, suitable for uplinks from access switches, aggregation layers, or data center interconnects. The module is designed to use XENPAK optics; a XENPAK transceiver is required for operation. In terms of power, configurations with the DFC3BXL typically draw around 402.36 W (9.58 A at 42 V). Fabric Channel mapping places ports 3 and 4 on Fabric Channel 1 and ports 1 and 2 on Fabric Channel 2, reflecting its interconnect topology within the chassis. This module is used where four 10GE links are needed from a single line-card slot, delivering scalable bandwidth while preserving port redundancy and simplified cabling in existing Catalyst 6500 deployments.
