Product Overview

The Cisco ASR-9903-FAN is the fan tray designed specifically for the Cisco ASR 9903 Compact High-Performance Router, a key component ensuring reliable thermal management in a fully redundant configuration. Part of the Cisco ASR 9000 Series, the ASR 9903 Router provides up to 3.6 Tbps of nonblocking, full-duplex capacity in a compact Three-Rack-Unit (3RU) form factor with a depth of 600 mm. The ASR-9903-FAN supports front-to-back airflow, critical for dense deployments in space-constrained environments such as mobile edge for 4G/5G networks, business PE, metro aggregation, cloud edge, Internet peering, and Data Center Interconnect (DCI).

Key Role in High-Performance Architecture

The ASR 9903 chassis integrates the ASR-9903-FAN as part of its redundant design, featuring two Route Processors (RPs), two integrated switch fabrics, 4 AC or DC power supply modules, and 4 fan modules. This configuration delivers power-optimized architecture with high-density multi-rate ports, including 400 Gigabit Ethernet, 200 Gigabit Ethernet, 100 Gigabit Ethernet, 40 Gigabit Ethernet, 25 Gigabit Ethernet, and 10 Gigabit Ethernet. The fixed board supports up to 1.6T data bandwidth with 16 integrated QSFP28-based 100GE ports and 20 integrated SFP+-based 10GE ports, configurable as 16x100GE, 15x100GE + 10x10GE, or 14x100GE + 20x10GE. Optional Port Expansion Cards (PECs) like the A9903-20HG-PEC (20 ports, max 2T bandwidth: 5 QSFP-DD/400GE-200GE-100GE + 15 QSFP28/100GE) and A9903-8HG-PEC (48 ports, max 800G bandwidth: 32 SFP28/25GE + 16 SFP+/10GE) further enhance flexibility.

Features and Benefits

  • Interface Support: Cisco Pluggable interfaces allowing mix and match of 10, 25, 40, 100, and 400 Gigabit Ethernet interface types across the chassis. All transceivers applicable on ASR 9903 are compatible with other ASR 9000 Series modular chassis. QSFP-DD optics share mechanical characteristics with QSFP28, supporting breakout to 25GE/10GE, 40GE, 100GE, 200GE, or 400GE.
  • Evolutionary Monitoring: Carrier-class OAM including NetFlow, IEEE 802.1ag, IEEE 802.3ah, ITU Y.1731, IP SLA, VCCV, ping, and traceroute.
  • Timing Capability: Hardware-based IEEE 1588, GPS/BITS interfaces, SyncE support. PTP Telecom profiles (G.8265.1, G.8275.1, G.8275.2), SyncE on Ethernet ports, GPS (10MHz, 1PPS, ToD), and two BITS interfaces for redundant synchronization.
  • Carrier-Grade Redundancy: Fully redundant with two RPs, two fabrics, 4 power supplies, 4 fan modules including ASR-9903-FAN.
  • Route Processor: Service edge-optimized with 64-bit Intel CPU, 32GB memory, external interfaces: console/auxiliary serial, two management Ethernet, Class A USB, GPS, two BITS.
  • Carrier-Class OS: Cisco IOS XR Software (64-bit), modular, patchable, scalable, highly available. Supported from Release 7.1.25.

The ASR-9903-FAN contributes to the platform’s efficiency by maintaining optimal temperatures in operating conditions from 41 to 104°F (5 to 40°C), with front-to-back airflow suited for rack mounting. It supports high service scales, reducing CapEx and OpEx while enabling predictable service infrastructure for enterprise border routing and ISP peering.
