2. Complete Detailed Product Overview

Product Line Positioning

Cisco 7204VXR is the enhanced upgraded 4-slot modular chassis within Cisco classic 7200 Series multi-service router family, released as a performance upgrade over the original non-VXR Cisco 7204. It features a redesigned dual PCI midplane with drastically improved total bandwidth up to 1.8 Gbps (vs 600 Mbps on base 7204) and compatibility with next-generation high-speed NPE-G1/G2 processing engines that the original 7204 cannot supportCisco. Targeted at small/mid-tier service providers and large enterprises, it unifies data, voice, video and security services on a single modular platform, serving as MPLS provider edge routers, VoIP TDM gateways, DSL/cable broadband concentrators and legacy ATM/Frame Relay migration gateways. The chassis reached End-of-Sale in 2012 and End-of-Support in 2017, replaced by ISR 4000/9000 and ASR series platforms.

Modular FRU Hardware Architecture (Key Differences vs Base 7204)

Single Rear-Mount Network Processing Engine (NPE) Slot

Supports full range of VXR-compatible processing engines, covering low to carrier-grade performance tiers; chassis power cycle required for NPE replacement (non-OIR):

Legacy low-tier: NPE-100 / NPE-150 / NPE-200 (shared with original 7204, capped at low throughput)
Mid-tier dedicated for VXR: NPE-225 (225 kpps), NPE-400 (400 kpps)
High-performance flagship exclusive to VXR:
- NPE-G1: 1 Mpps forwarding rate, onboard 3×GE ports, max 1GB DRAM, Compact Flash storage support
- NPE-G2: Up to 2 Mpps forwarding rate, highest performance of 7200 series, up to 2GB DRAM
  
  The VXR dual independent PCI midplane delivers 1.8 Gbps aggregate bandwidth, eliminating severe bandwidth oversubscription issues on the original single-bus 7204 chassisCisco.

Four Front Hot-Swap Port Adapter (PA) Slots (OIR Supported)

All four PA bays support Online Insertion and Removal for live interface card replacement without power outage, fully compatible with all standard 7200 series port adapters for mixed-media convergence:

Ethernet PAs: 10/100 Fast Ethernet, Gigabit Ethernet, EtherSwitch Layer 2 switch modules
Serial/TDM PAs: Multi-channel T1/E1 PRI, T3/E3, HSSI, ISDN BRI/PRI
Optical WAN PAs: OC-3 ATM, POS Packet over SONET, ATM-CES voice trunk modules
Service PAs: VPN Acceleration Module (VAM) for dedicated IPsec crypto offload, dual-wide voice trunk adapters

Unused slots must be covered with blank filler panels for airflow and EMI compliance.

Upgradable Modular I/O Controller FRU (VXR Exclusive Upgrade Option)

Unlike fixed integrated I/O on base 7204, 7204VXR supports field-replaceable I/O controller variants for flexible management expansion:

Base I/O: 1×10M MII Ethernet + RJ45 Console + RJ45 Aux
I/O-2FE: Dual 10/100 Fast Ethernet management ports
I/O-GE+E: Integrated Gigabit Ethernet management port for high-speed out-of-band accessCisco

Console/Aux ports provide RS232 local CLI and dial-up modem remote maintenance access.

Hot-Swap Cooling & Redundant Power Subsystem (Enhanced vs Base 7204)

Hot-swappable fan tray: Side-to-side airflow, replaceable without full chassis power cycle (original 7204 fan tray is non-OIR)
Dual rear power supply bays: Interchangeable 280W AC (100–240VAC) or 370W DC (-48VDC) power units, supporting standalone single power or N+1 load-sharing redundant power protection; mixed AC/DC supplies are not permittedCisco
