The Cisco NCS-55A2-MOD-SE-S is a 2RU fixed aggregation router from the Network Convergence System 5500 family. It combines 24 ports of 10G SFP+ and 16 ports of 1/10/25G with two modular bays for Modular Port Adapters, giving flexible port and service options in a compact low power platform.
The Scale Enhanced variant runs an 8 core CPU and supports up to 4 million FIB entries, which makes it suited to internet peering and dense converged aggregation roles where route scale matters. It runs 64 bit Cisco IOS XR and supports L2VPN and L3VPN services, segment routing, ultra wide ECMP, MACsec encryption and streaming telemetry.
Configuration as supplied: one NC55-MPA-4H-S four port QSFP28 or QSFP+ module fitted in MPA bay 1, blanking plate in bay 2, and two 930W DC power supplies with DC power cables. Please note that the power supplies are DC and not AC, which suits telco and central office environments.
Airflow is port-side exhaust, meaning air enters at the power supply and fan side and leaves through the port side, back to front. Confirm that this matches your rack aisle layout before ordering. Supplied without original box and rails.
