The ASR5K-041GE-LX-K9 is a Cisco QGLC 4-port Gigabit Ethernet line card for ASR 5000/5500 series, featuring 1000BASE-LX/LH SFPs for up to 10 km single-mode fiber connectivity.
The ASR5K-041GE-LX-K9 is supported in Cisco ASR 5001, 5002, 5004, 5010, 5020 and ASR 5500 series chassis with an available Gigabit Ethernet line-card slot.
Using 1000BASE-LX/LH SFPs, the ASR5K-041GE-LX-K9 supports single-mode fiber distances up to 10 km over standard SMF at 1310 nm wavelength.
Power down or hot-swap the ASR chassis per Cisco guidelines, slide the ASR5K-041GE-LX-K9 into an available GE slot, secure the handle, then power up and verify with 'show card'.
The ASR5K-041GE-LX-K9 requires Cisco IOS XR 4.2.1 or later to enable full Gigabit Ethernet LX functionality and feature support.
The ASR5K-041GE-LX-K9 delivers up to 4 Gbps aggregated line-rate throughput across its four Gigabit Ethernet ports.
Typical power draw for the ASR5K-041GE-LX-K9 is approximately 20 W under full load, complying with ASR 5000 series power-budget guidelines.
Operating temperature: 0–40 °C; relative humidity: 5–90% non-condensing. Storage: –40–70 °C. The card meets Cisco environmental standards for data-center deployment.
Yes. The ASR5K-041GE-LX-K9 supports IEEE 802.1Q VLAN tagging and QinQ stacking for advanced traffic segmentation and carrier-grade networking.
No. The ASR5K-041GE-LX-K9 operates under the base IOS XR license set; no extra feature license is needed for standard Gigabit Ethernet LX ports.
The line card supports IPv4, IPv6, MPLS, QoS, NetFlow, and advanced routing features available in the ASR 5000 series software.
Yes. The ASR5K-041GE-LX-K9 coexists with copper-based and other fiber line cards in the ASR 5000/5500 chassis, enabling hybrid Gigabit Ethernet deployments.
Use CLI: 'configure', then 'interface GigabitEthernet <slot>/<subslot>/<port>'. Assign IP or switchport mode, then 'no shutdown' to activate the interface.
Verify SFP seating, check fiber continuity, use 'show interfaces' for status, inspect SFP LED indicators, and confirm IOS XR compatibility and port configuration.
The ASR5K-041GE-LX-K9 is covered under Cisco’s limited lifetime hardware warranty, with options for Cisco Smart Net Total Care and software support contracts.
Ideal for enterprise edge, data-center aggregation, mobile backhaul, and service-provider access networks requiring long-haul Gigabit Ethernet connectivity.
