Cisco WS-SUP720-3B Catalyst 6500 Series Supervisor Engine

Cisco WS-SUP720-3B is the Catalyst 6500/Cisco 7600 Series Supervisor Engine 720 module that provides the control plane and fabric for the chassis, shipped with a factory-installed PFC3B (Policy Feature Card) and MSFC3 (Fabric MSFC). It supports hardware-based routing with MPLS and IPv6 and is compatible with all Catalyst 6500 interface module classes (Classic, CEF256, dCEF256, and CEF720). The unit’s physical profile lists dimensions of 4.0 x 37.9 x 40.3 cm and a weight of about 11.5 lb, with a rated power draw of 282 W (6.72 A). Operating conditions specify a 0 to 40°C ambient range and 10 to 90% noncondensing humidity. Memory options include MEM-S3-1GB for 1 GB DRAM on Sup720 and Sup720-3B and MEM-MSFC3-1GB for the MSFC3 module, allowing expandable DRAM as needed. This supervisor engine is intended for deployment in core, distribution, or data-center roles within Catalyst 6500/Cisco 7600 networks and requires a high-speed fan tray (such as Fan Tray 2 or a Catalyst 6500-E series fan tray) for proper cooling.
