Description

The NCS 540 N540X-16Z4G8Q2C-A is a 1RU service provider router running Cisco IOS XR. It is built for cost-effective access and aggregation, including 5G mobile backhaul, metro and converged access, and its temperature-hardened design suits both indoor and outdoor cabinet deployments. An integrated GNSS receiver and Class C timing make it a fit for networks that need accurate phase and time synchronisation.

This AC power variant provides 16 x 1GE/10GE SFP/SFP+ ports, 8 x 1GE/10GE/25GE SFP/SFP28 ports, 2 x 40GE/100GE QSFP28 ports and 4 x 1GE RJ-45 (10/100M) copper ports. Forwarding performance reaches up to 300 Mpps, backed by an 8-core 1.7GHz x86 CPU, 8GB DRAM and 32GB of storage. Power comes from a fixed single AC supply accepting 90-265V AC at 50-60Hz, and the chassis operates from -40 C to +70 C. The router ships with the XR-7.0-AC-TRK software image, and additional capacity and feature licences are available as Right-to-Use or Subscription options per 10G.

Supported optics are listed in the Cisco Transceiver Module Group Compatibility Matrix. Rack mount kits N540-RCKMT-19-EGA, N540-RCKMT-23-EGA and N540-RKMT-ETSI-EGA, the N540-CBL-BRKT-EG cable bracket and the N540-X-BB-FAN fan tray are available for this model.
