Description

The N540-PWR750-D is a hot-swappable 750W DC power supply module for Cisco NCS 540 Series routers. It suits DC-powered telecom and service provider deployments of NCS 540 platforms, including fronthaul, access and aggregation roles.

This variant takes a nominal -48 VDC input and delivers 750W. It is the DC-input counterpart to the N540-PWR750-A, which is the AC-input version of the same 750W power supply option listed for the NCS 540 range. Being hot-swappable, it can be fitted or replaced in a chassis without taking the router out of service, provided a redundant supply is installed.

Choose this module where the site is fed from a -48 VDC battery plant or DC distribution system rather than mains AC.

Enquire with XS Network Tech for new or used pricing and availability.
