The Cisco A901-4C-F-D ASR 901 Aggregation Services Router is a carrier-grade Ethernet routing platform designed for Carrier Ethernet, Metro Ethernet, mobile backhaul, and enterprise WAN edge deployments. Featuring a Pay-As-You-Grow 4-port Gigabit Ethernet configuration, the router provides flexible copper and fiber connectivity through compatible Gigabit Ethernet interfaces. Its compact 1U chassis with dual DC power inputs is well suited for service provider, utility, industrial, and demanding remote network environments.
Powered by Cisco IOS XE, the A901-4C-F-D supports advanced Layer 2 and Layer 3 services, MPLS, L2VPN, L3VPN, IPv4/IPv6, Carrier Ethernet, Metro Ethernet, QoS, and Synchronous Ethernet (SyncE). Its PAYG licensing model allows supported copper and SFP interfaces to be enabled as network requirements grow, while timing capabilities including BITS, 10 MHz, 1 PPS, ToD, and optional IEEE 1588v2 support make it suitable for synchronization-sensitive applications.
The Cisco A901-4C-F-D is an ideal solution for Carrier Ethernet access, Metro Ethernet aggregation, mobile backhaul, enterprise WAN edge routing, utility networks, industrial networking, and service provider access infrastructure. Its redundant DC power architecture, carrier-grade reliability, flexible port licensing, and extended operating temperature range provide a scalable foundation for resilient Ethernet aggregation.
