Cisco ASR-9904-AC Router | ASR 9000 Series AC Chassis

Quick Specs

Specifications are based on Cisco's ASR 9904 chassis documentation. Confirm exact hardware revision and included modules before purchase.

3. Technical Specifications

Configuration note: The ASR-9904-AC model designation identifies the AC chassis variant. It should not automatically be treated as a complete, ready-to-deploy router. RSPs, line cards, power modules and other accessories must be verified against the actual quotation and bill of materials.

4. Product Overview

The Cisco ASR-9904-AC Router Chassis is part of the Cisco ASR 9000 Series Aggregation Services Routers, designed for service provider networks and demanding IP/MPLS aggregation environments. Its compact 6 RU chassis combines modular line-card expansion with redundant route-processing architecture, making it suitable for network edge deployments where reliability, scalability and service flexibility are important.

The ASR 9904 supports two line-card slots and dual redundant Route Switch Processors (RSPs) with integrated fabric. This architecture enables network operators to build a configurable routing platform for carrier Ethernet, Layer 2 and Layer 3 VPN services, IP/MPLS transport and other supported service-provider applications. Supported features depend on the installed cards and Cisco IOS XR software release.

Key Benefits

• Modular architecture: Configure line cards and route processors to match network capacity and service requirements.

• High availability: Supports redundant route processors and AC power redundancy when appropriately configured.

• Space-efficient deployment: The 6 RU chassis is designed for rack and telecommunications cabinet installations.

• Service-provider applications: Suitable for supported carrier Ethernet, IP/MPLS, VPN and aggregation deployments.

• Flexible configuration: Hardware selection can be tailored to interface requirements, network topology and deployment needs.

Typical Applications

• Service provider edge routing

• Carrier Ethernet aggregation

• IP/MPLS backbone and metro networks

• Enterprise WAN aggregation

• Layer 2 VPN and Layer 3 VPN services

• Mobile backhaul and transport networks

Confirm the required interface speeds, port types, software features and redundancy level before selecting the final configuration.

5. FAQ

Q1: What is the Cisco ASR-9904-AC used for?

The Cisco ASR-9904-AC is an AC-powered modular router chassis designed for service provider and carrier-grade networking. Typical applications include IP/MPLS routing, carrier Ethernet aggregation, WAN edge connectivity and supported VPN services.

Q2: What is the difference between Cisco ASR-9904-AC and ASR-9904-DC?

The main distinction is the power configuration.

Both belong to the ASR 9904 platform family. Verify the exact chassis, power entry module and power supplies before ordering. AC and DC modules should not be mixed in the same configuration.

Q3: Does the Cisco ASR-9904-AC include line cards and route processors?

Not necessarily. The model number identifies the chassis variant, but the supplied configuration may differ by seller and product condition. Ask for a complete bill of materials confirming the RSPs, line cards, power modules, fan tray and required accessories.

Q4: How many line cards does the ASR 9904 support?

The ASR 9904 chassis has two line-card slots and two RSP slots for a redundant route-processing configuration. Actual interface capacity depends on the selected line cards and supported hardware combination.

Q5: How does the Cisco ASR 9904 compare with other ASR 9000 models?

The ASR 9904 is a compact 6 RU platform with two line-card slots. Larger chassis in the ASR 9000 family can offer more expansion capacity, depending on the model. The best choice depends on port density, throughput requirements, redundancy, rack space and future expansion plans.

Q6: How can buyers verify compatibility before ordering?

Provide your current router model, required port types and speeds, existing RSP and line-card part numbers, IOS XR version, and power requirements. These details help establish whether the proposed configuration is compatible with your network.

Q7: What after-sales support should a supplier provide?

A professional supplier should be able to provide:

• Model and part-number verification before shipment.

• Confirmation of product condition and included accessories.

• Pre-shipment photographs and serial-number verification, where available.

• Packing and shipping information for international orders.

• A clearly stated warranty, return policy and process for reporting defective items.

Warranty coverage and technical support depend on the supplier's terms and the product's eligibility for manufacturer support. Confirm these terms in writing before purchasing.

Q8: Can I request a quotation for Cisco ASR-9904-AC?

Yes. For a more accurate quotation, specify the required quantity, new or refurbished condition, destination country, and whether you need the chassis only or a fully configured system. Request the complete bill of materials to avoid unexpected component costs.
