Nokia 7210 SAS-K ETR Service Router - Carrier Ethernet IP/MPLS Switch

Nokia 7210 SAS-K ETR Carrier-Grade Service Access Switch

The Nokia 7210 SAS-K ETR is a certified refurbished carrier-grade service access switch/router featuring Nokia's programmable datapath silicon, available in three models with system throughput ranging from 5 Gb/s to 30 Gb/s wire speed (full duplex IMIX), operating temperature range of -40°C to +65°C, multiple network interfaces including SFP/SFP+ ports and combo RJ-45 Gigabit Ethernet ports, comprehensive IP/MPLS/Ethernet transport capabilities, and enhanced environmental certifications for power substations and railway deployments. This professional-grade networking solution delivers secure Carrier Ethernet connectivity with advanced routing protocols, deep buffer memory for burst absorption, and passive fanless cooling, making it ideal for network demarcation in enterprise business services, wholesale carrier networks, and mobile anyhaul applications where reliability and extended operating conditions are paramount.

Enterprise-Ready Network Performance

This certified refurbished Nokia 7210 SAS-K ETR series provides three performance tiers to match your specific deployment requirements. The K30 ETR model delivers 30 Gb/s throughput with 512 MB buffer memory and features three SFP+ 10GE ports plus eight combo SFP/RJ-45 Gigabit ports. The K12 ETR offers 9 Gb/s throughput with 64 MB buffer memory and twelve network interfaces combining SFP and Gigabit Ethernet connectivity. The K5 ETR provides 5 Gb/s throughput optimised for compact edge deployments with five total network interfaces. All models support ITU-T SyncE with Ethernet Synchronisation Messaging Channel and IEEE 1588v2 precision timing protocols, ensuring accurate network synchronisation for carrier-grade applications.

Advanced Layer 2 and IP/MPLS Services

The Nokia 7210 SAS-K ETR series runs the proven Service Router Operating System (SR OS), delivering comprehensive networking capabilities across all three models. Layer 2 services include Virtual Private LAN Service (VPLS), Virtual Leased Line (VLL), IEEE 802.1Q VLAN and 802.1ad QinQ tagging, Link Aggregation Groups, and ITU-T G.8032v2 Ethernet ring protection. The K30 and K12 ETR models additionally support full IP/MPLS routing with Segment Routing, MPLS Label Edge Router and Label Switch Router functions, BGP/OSPF/IS-IS protocols, IP VPN services for both IPv4 and IPv6, and multi-chassis LAG for enhanced redundancy. All units provide hierarchical quality of service with per-service ingress and egress policing, deep buffering to absorb traffic bursts, and comprehensive OAM capabilities including IEEE 802.1ag and ITU-T Y.1731 Ethernet OAM.

Operating System Advantages

The Nokia Service Router Operating System (SR OS) offers significant advantages for carrier and enterprise networks, including proven stability across thousands of global deployments, seamless integration with Nokia's broader routing portfolio, and comprehensive support for modern networking protocols. SR OS provides automated configuration capabilities, remote upgrade functionality, and extensive NETCONF/YANG programmability for software-defined networking environments. However, the operating system requires specialised networking knowledge to configure and manage effectively, may have a steeper learning curve compared to consumer-grade network equipment, and typically requires familiarity with carrier-grade networking concepts and protocols.
