Redundant SUP720 chassis provided stable performance for mid-size deployments.
Handles traffic efficiently and predictably.
Cisco hardware ensures minimal downtime.
Reliable and easy to manage.
Professional-grade enterprise solution.
The Cisco 7603S Chassis offers a 3-slot modular design, redundant Supervisor Engine 720-3B modules, dual hot-swappable power supplies, 720 Gbps system bandwidth per slot, and NEBS Level 3 compliance, ensuring high availability and scalability for enterprise and service provider networks.
Redundant Supervisor Engine 720-3B modules operate in active/standby mode, enabling hitless failover within 200 ms and maintaining control-plane continuity, which minimizes downtime and ensures uninterrupted data forwarding during hardware maintenance or faults.
The Cisco 7603S chassis comes standard with two hot-swappable 2700W AC power supplies, supporting N+1 redundancy and load-sharing. This configuration delivers up to 5400W of combined power for line cards, supervisors, and fabric modules.
Compatible line cards include Cisco 7600 series Ethernet and service modules such as the 48-port Gigabit Ethernet, 16-port 10 Gigabit Ethernet, and multiservice broadband modules. Each line card leverages the 720 Gbps per-slot fabric connectivity.
The Cisco 7603S chassis delivers up to 1.44 Tbps total backplane capacity and 720 Gbps per slot, supporting up to 192 10/100/1000 ports or 32 10-Gigabit Ethernet ports with full line-rate performance.
Management options include a dedicated out-of-band RJ-45 console port, an auxiliary serial port, an Ethernet management port for Cisco IOS RPC, and optional In-Service Software Upgrade (ISSU) support for Supervisor Engine modules.
Yes. When equipped with redundant Supervisor Engine 720-3B modules running Cisco IOS Release 15.x or later, the chassis supports ISSU, allowing software updates without disrupting data-plane traffic.
The chassis meets NEBS Level 3, ETSI, and GR-63 standards. Operating temperature ranges from 0°C to 40°C, storage from –40°C to 70°C, and it supports relative humidity from 5% to 85% non-condensing.
The 7603S chassis ships with front and rear rack-mount kits, including brackets and screws. It occupies 9 RU in a standard 19” rack and requires proper airflow clearance and cable management.
Cisco offers a 90-day limited hardware warranty, with optional extensions up to 5 years. Cisco SMARTnet contracts provide 24x7 technical support, advanced replacement, and software updates for the chassis and Supervisor Engine modules.
Yes. The chassis and Supervisor Engine 720-3B support full IPv6 routing protocols, including OSPFv3, BGP4+, and RIPng, ensuring IPv6 data-plane forwarding at line rate alongside IPv4.
The chassis and Supervisor Engine 720-3B require a base feature set license included in the hardware purchase. Advanced features like MPLS, multicast, and security require Cisco IOS feature licenses, which can be ordered separately.
Upgrading involves swapping the existing chassis with the 7603S, reusing compatible line cards and power supplies, installing new Supervisors, and migrating configurations via Cisco IOS commands or configuration files.
The 7603S is ideal for campus aggregation, small service provider edge, and data center spine deployments that require high performance, redundancy, and IPv6 readiness in a compact 9 RU footprint.
With 3 modular slots, redundant supervisors, up to 5400W power capacity, and 720 Gbps per-slot bandwidth, the 7603S chassis scales by adding higher-density line cards or service modules without disrupting existing services.
Genuine Cisco parts and accessories can be purchased through certified Cisco partners, authorized distributors, or directly via the Cisco Commerce Workspace, ensuring full warranty coverage and technical support.
