The MX10K-LC2101-R is a Juniper Networks 24×100G/24×40G/96×10G interface line card in R mode designed for high-density 100G, 40G, and 10G connectivity on the MX10008 and JNP10008 routing platforms.
The MX10K-LC2101-R is fully compatible with the Juniper MX10008 and JNP10008 core routers running Junos OS Release 20.4 or later.
This line card supports up to 24 100GbE, 24 40GbE, or 96 10GbE ports, all simultaneously configurable under a unified interface profile.
The MX10K-LC2101-R delivers up to 4.8 Tbps of bidirectional system throughput when fully populated with 100GbE ports.
The line card consumes approximately 600 W at full load and requires redundant high-efficiency AC or DC power supplies per MX10008 chassis specifications.
Yes, in R mode the line card supports full MPLS, EVPN-VXLAN, SR-MPLS, and Segment Routing capabilities as part of the Junos OS control plane.
Power down the MX10008 chassis, slide the MX10K-LC2101-R into an available line-card slot, secure the ejector handles, and power up the router following Juniper installation guidelines.
No additional interface license is required; all port capabilities are enabled by the MX10008 chassis license and Junos OS software feature set.
The MX10K-LC2101-R is a full-width, single-slot line card measuring 44.5 cm (17.5 in) deep and 6.5 cm (2.6 in) wide.
Each 100G port can break out into four 25G interfaces, and each 40G port can break out into four 10G interfaces using compatible breakout cables.
The line card requires the MX10008 chassis fan trays rated at 200 CFM per tray to maintain optimal operating temperatures between 0 °C and 40 °C.
Juniper provides a one-year limited hardware warranty with optional Juniper Care and J-Care support contracts for 24×7 hardware replacement and software upgrades.
No. All line cards in a single MX10008 chassis must operate in the same mode (R or Q) to ensure consistent forwarding plane behavior.
The line card is ideal for large-scale data center spine deployments, metro aggregation, and high-capacity peering applications requiring flexible port speeds.
With 4.8 Tbps capacity and flexible port configurations, the MX10K-LC2101-R allows seamless scaling from 10G to 100G without additional infrastructure.
The MX10K-LC2101-R is available through Juniper authorized resellers and distributors; contact your local Juniper sales representative for pricing and lead times.
