RJ45 card worked perfectly in AR series routers.
Stable gigabit connectivity across all ports.
Good L2 performance.
Installation was straightforward.
Reliable for branch deployments.
Meets expectations for enterprise routing.
The AR-4ES2G-S is a Huawei PIC/SIC module providing four Gigabit RJ45 Ethernet ports for high-performance L2 switching in AR series routers.
The AR-4ES2G-S is compatible with Huawei AR1200, AR2200, AR3200, AR3600 and AR5600 series routers equipped with a SIC slot.
It offers four independent 1000 Mbps RJ45 Ethernet ports supporting full-duplex Gigabit connectivity.
1000BASE-T is the IEEE standard for Gigabit over Cat5e/Cat6; RJ45 denotes the connector type used by 1000BASE-T interfaces.
No additional license is required; ensure your router runs Huawei VRP firmware version V5R3 or later for full feature support.
Power off the router, insert the AR-4ES2G-S into the SIC slot until it clicks, secure the latch, then power on and verify with 'display card'.
No. To avoid hardware damage and ensure proper recognition, install or remove the card only when the router is powered off.
It suits enterprise campus aggregation, branch office connectivity, VPN gateways and high-density user access scenarios.
It supports Cat5e, Cat6, and Cat6a copper cables for Gigabit Ethernet over 100 meters maximum distance.
Typical power consumption is 3.5 W; ensure your router’s PSU can supply an additional 5 W margin per SIC.
It supports IEEE 802.1Q VLAN tagging, QinQ, 802.1p QoS, IGMP snooping and port-based traffic shaping.
Huawei provides a one-year limited hardware warranty covering defects in materials and workmanship under normal use.
It’s managed via Huawei VRP CLI or eSight NMS on Linux and Windows platforms; no host OS driver is needed.
It supports line-rate forwarding of up to 8 Gbps aggregate throughput across all four ports.
Operating temperature: –40 °C to 70 °C; humidity: 5%–95% non-condensing; compliant with RoHS and WEEE.
Order through authorized Huawei channel partners or e-commerce platforms; global shipping options available with standard lead time of 3–5 business days.
