Description

The Cisco NCS 540 Fronthaul N540-FH-AGG-SYS is a 1RU aggregation router built for 5G and 4G LTE fronthaul and mid-haul transport in Cloud RAN and Centralised RAN designs. It aggregates CPRI, eCPRI and Ethernet traffic from cell-site routers and radio units, and suits indoor or protected-cabinet deployments as part of a Converged SDN Transport architecture. It runs Cisco IOS XR.

The front panel provides 24 universal 1/10/25G ports that can carry CPRI option 3-8, eCPRI or Ethernet, plus 4x 100G ports, with throughput of up to 900 Gbps. An FPGA-extended forwarding plane keeps forwarding latency typically under 10 microseconds. An 8-core 1.7 GHz x86 CPU with 8 GB DRAM and 32 GB storage runs the control plane. Timing is handled by SyncE and IEEE 1588 PTP, with G.8273.2 Class B/C support and 1pps, 10MHz, ToD and GNSS antenna interfaces.

This C-Temp aggregation SKU uses two hot-swappable N540-PWR750 power supplies in 1+1 redundancy (AC or DC) and six modular fans in 5+1 redundancy with front-to-back airflow. Maximum power draw is 700 W. It supports optics listed in the Cisco TMG Compatibility Matrix for NCS 540 and the N540 rack kit options.
