About the Cisco ASR 900 A901-4C-F-D Cisco ASR 900 series module / router
The Cisco ASR 900 A901-4C-F-D delivers compact, high-density WAN/LAN connectivity with four Gigabit Ethernet combo ports (SFP/RJ-45) and two 10GE SFP+ uplink ports, making it an ideal choice for service providers and network engineers seeking space-efficient edge routing in 1U rack-mountable or wall-mountable form factors.
Built on Cisco's proven ASR 900 Series architecture, the ASR 901 model combines hardware-based distributed forwarding with comprehensive MPLS support—including MPLS VPN, L2VPN, and L3VPN services—plus advanced timing and synchronization capabilities via IEEE 1588v2 PTP and Synchronous Ethernet. The platform runs Cisco IOS or IOS XE software, supporting industry-standard routing protocols such as BGP, OSPF, IS-IS, RSVP-TE, LDP, and static routing. With hierarchical QoS, traffic shaping, policing, and classification built in, the A901-4C-F-D meets stringent service-level requirements across mobile backhaul, business services, and carrier-grade networks. Extended operating temperature ratings from −40°C to +65°C and NEBS Level 3 compliance ensure reliable deployment in outdoor and street-cabinet environments. Dual DC or dual AC power inputs (field-selectable; this unit features DC power, denoted by the '−D' suffix) provide flexible power architecture for distributed network nodes. Network management is simplified through SNMP, NETCONF, and Cisco EPN Manager integration, with dedicated console and out-of-band management Ethernet ports for secure administration.
