Overview

The Cisco A900-PWR1200-A is a 1200W AC Power Supply designed for the ASR 900 Series and compatible with the Cisco Network Convergence System (NCS) 560-7 Router. This field-replaceable unit (FRU) provides reliable power delivery in modular aggregation platforms optimized for broadband, mobile backhaul, and Metro Ethernet applications.

Key Features and Design

  • Supports up to three power supplies per chassis in load-share mode or 2+1 protection scheme.
  • System operates on a single power supply; mixing of AC and DC power supplies in a single chassis is supported.
  • Shallow depth and side-to-side airflow design enable deployment in compact spaces like ETSI 300-mm deep cabinets.
  • Qualified for extended temperature ranges, supporting industrial conditions from -40 to 65°C for AC operation with 1200W power supply.
  • Enhances high availability with in-box hardware redundancy and In-Service Software Upgrade (ISSU) support.

Deployment Flexibility

The A900-PWR1200-A is part of a fully modular system featuring redundant Route Switch Processors (RSPs), high-speed fan trays, and up to 16 interface modules. It contributes to low power consumption and high Ethernet interface density, with support for 1G/10G/40G/100G ports. The power supply enables precise frequency and phase/time synchronization using SyncE, IEEE-1588 PTP, and GPS interfaces.

Ideal for remote Point-of-Presence (POP) and aggregation sites, it supports Layer 2 VPN, Layer 3 VPN, Ethernet VPN (EVPN), and Multicast services. The platform is 5G ready with Segment Routing and EVPN, MEF 3.0 certified, and part of Cisco Certified Metro Fabric Design.

Operational Efficiency and Reliability

  • Online field replacement for power supplies, fan trays, RSPs, and interface modules without system downtime.
  • Rich QoS capabilities for SLAs, low latency forwarding (<10 µs), and security features including Trust Anchor, secure boot, and runtime defense.
  • Proactive diagnostics, telemetry, and programmability via Cisco IOS XR Software for simplified management.
  • Supports Cisco Evolved Programmable Network (EPN) architectures and EPN Manager for end-to-end orchestration.

System Integration

In the NCS 560-7 Router, the chassis includes 3 power supply slots, 2 RSP slots, 16 interface module slots, and 1 fan tray with redundancy. The A900-PWR1200-A ensures maximum input power of 1680W (fully loaded at 55°C), equivalent to 5800 BTU/hr. It operates in load-share mode with multiple supplies, enhancing redundancy for converged mobile, residential, and business services.

The router’s compact 7 RU form factor (height 12.22 in./310.38 mm, width 17.44 in./443 mm, depth 9.22 in./234.2 mm) weighs up to 69.32 lb (31.4 kg) fully loaded, supporting rack mounts for 19 in. and 23 in. racks, plus ETSI kits.
