Description

The N540-PWR400-A is a 400W AC power supply module for modular Cisco Network Convergence System 540 series routers. It suits service provider access and aggregation sites, mobile backhaul and cell-site deployments where the NCS 540 platform is fitted in indoor or outdoor cabinets.

This SKU is the AC version of the N540-PWR400 family. It is rated at 400W and takes a 100-240 VAC input at 50/60 Hz. Its DC counterpart is the N540-PWR400-D, so choose this part when the site is fed from AC mains rather than a DC battery plant. The module is field-replaceable and hot-swappable, and two supplies can be installed as a pair for 1+1 power redundancy on NCS 540 models with swappable supplies.

The power supply sits alongside the N540-FAN fan module and the N540-RCKMT-19, N540-RCKMT-23 and N540-RKMT-ETSI rackmount kits listed for the AC variant. Check the exact router model before ordering, because some NCS 540 models use fixed rather than modular power supplies.

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

Q: Is this the AC or DC power supply?
A: The N540-PWR400-A is the AC version, with a 100-240 VAC input. The DC equivalent is the N540-PWR400-D.

Q: Which fan module and rackmount kits go with the AC variant?
