Description

The N540-PWR750-A is a hot-swappable 750W AC power supply module for the Cisco Network Convergence System 540 (NCS 540) range. It is listed as the AC power supply for the NCS 540 Fronthaul Aggregation Router (N540-FH-AGG-SYS), used in mobile transport and 5G fronthaul or aggregation sites.

This is the AC input version, accepting 100-240 VAC at 50/60 Hz, which makes it suitable for worldwide AC deployments. Its DC counterpart is the N540-PWR750-D, so choose this -A model where the site supplies mains AC. The aggregation chassis it serves draws up to 700W at maximum load, and two supplies can be installed together for 1+1 power redundancy.

Being field-replaceable and hot-swappable, a PSU can be exchanged without taking the router out of service when a redundant pair is fitted. It is typically ordered alongside the N540-FAN-FHA fan assembly and N540-RKM rack mounting kits for the same chassis.

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