Chapter 2 Route Switch Processors and Supervisor Engines
Route Switch Processor 720
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 2-8 for more information.
Figure 2-1 shows the RSP720-3C-GE front panel, which is the same as the RSP720-3CXL-GE front
panel. See Table 2-2 and Table 2-3 for information about the front-panel controls and LEDs.
