Ubiquiti EdgeRouter Infinity | ER-8-XG 8-Port 10G SFP+ Router

Ubiquiti EdgeMAX EdgeRouter Infinity (ER-8-XG)

The Ubiquiti ER-8-XG (EdgeRouter Infinity) is an enterprise-grade core routing gateway built for massive throughput, high-density packet forwarding, and absolute infrastructure redundancy. Occupying a standard 1U rackmount chassis, this flagship carrier-class platform is engineered for regional internet service providers (ISPs), core data centres, high-volume corporate backbones, and complex multi-site enterprise topologies.

Powered by a massive 16-core processing engine, the ER-8-XG delivers an exceptional layer 3 forwarding rate of 18 million packets per second (Mpps) for small 64-byte packets and scales seamlessly to an 80 Gbps aggregate line rate capacity.

16-Core Heavyweight Compute Processing Brain

The internal processing hardware is built to handle intensive internet border routing and intensive protocol tables simultaneously without bottlenecking:

• 1.8 GHz MIPS64 Network Engine: Driven by an industrial 16-core processor running at 1.8 GHz per core, providing immense computational capacity for high-stress throughput spikes.

• 16 GB DDR4 RAM Cache: Backed by 16 GB of ultra-fast DDR4 system memory. This extensive RAM cache allows the router to store multiple full global BGP routing tables natively, making it a reliable choice for edge routing applications.

• Hardware Acceleration Array: Features dedicated on-die hardware-offload processors that bypass the main CPU cores to manage core network address translation (NAT), stateful firewalls, and deep packet filtering directly at full wire speed.

High-Density 10G SFP+ Fibre Interface Grid

The front panel layout provides direct access to high-capacity optical connections, eliminating localised media translation devices:

• Eight Autonomous 10 Gbps SFP+ Ports: Features eight independent 10G SFP+ transceiver cages that operate on a dedicated non-blocking matrix. Each port can function as a completely separate Layer 3 routed boundary or bind together into multi-link LACP trunk paths.

• Dual Mode SFP Flexibility: The SFP+ ports are arranged into two individual groups of four. Via software configuration, each block can be toggled to accept legacy 1G SFP transceivers or high-speed 10G SFP+ optics based on project infrastructure demands.

• Dedicated Copper Out-of-Band Management: Outfitted with an isolated Gigabit RJ45 copper interface (eth0) designed for out-of-band management access, along with a standard RJ45 serial console port for direct command line control.

Carrier-Tier Redundant Power Supply Framework

To minimise system downtime from local electrical utility failures, the ER-8-XG utilises a modular, fault-tolerant power setup:

• Dual Hot-Swappable 100W AC/DC Modules: Ships standard with two pre-installed, load-sharing 100W AC/DC power supply units (RPS-AC-100W). The chassis distributes power load across both units simultaneously. If one grid fails, the other instantly assumes the entire power load with zero drop-outs.

• Optional DC/DC Customisation: For telecom distribution spaces running isolated battery banks, the factory modules can be hot-swapped for secondary DC/DC modules (RPS-DC-100W, available separately) to accept native 38V to 54V DC power.

Port Assignment & Interface Matrix

Hardened Bare-Metal EdgeOS Operating Suite

• Industrial Protocol Options: Driven natively by EdgeOS, providing full access to core provider technologies including dynamic OSPFv3, BGP4 with extensive IPv6 prefix parsing, RIPng, MPLS framing, and advanced VPLS service mappings.

• Granular Zone-Based Security: Features comprehensive access control list (ACL) rulesets and a highly scalable zone-based firewall architecture, managing thousands of simultaneous traffic sessions with deep packet inspection (DPI) packet grouping.

• Centralised UISP Node Integration: Can be fully adopted into the cloud-hosted Ubiquiti Internet Service Provider (UISP) software platform. This central dashboard allows operators to track optical transceiver laser levels, push bulk firmware updates, and view historic traffic trends remotely.
