Route Switch Processor 720

This section describes the Route Switch Processor 720 (RSP720). The Cisco 7600 RSP720 consists of a full-size board and two integrated daughter cards: the MSFC4 and a PFC3C or PFC3CXL. The RSP720 has an integrated switch fabric that interconnects all of the line cards in the Cisco 7600 router with point-to-point 20-Gbps full-duplex serial channels.

Note	• Cisco IOS Release 12.2SRB and later releases support the RSP720; earlier releases do not.
	The RSP720 is supported on all Cisco 7600 routers (including enhanced chassis) except the Cisco
	7603 and the Cisco OSR-7609.
	• Cisco IOS Release 12.2SRC and later releases support an RSP720 that has 10GE uplinks
	(RSP720-3C-10GE and RSP720-3CXL-10GE). See the “RSP720 with 10GE Uplink Ports” section
	on page 2-8for more information.
	Figure 2-1shows the RSP720-3C-GE front panel, which is the same as the RSP720-3CXL-GE front
	panel. See Table 2-2and Table 2-3for information about the front-panel controls and LEDs.
