Rsp4/4+-Cisco 7507, Cisco 7513, And Cisco 7576 - Cisco 7500 Series Configuration Manual

Chapter 1 Cisco 7500 Series Product Overview
•
•
The RSP2 supports high system availability (HSA), which is a feature in Cisco IOS Release 11.1(4) or
later, allowing two RSPs to be used in a Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX
router.
Note The Cisco 7576 uses only one RSP slot per router, designated router A and router B; therefore, it does
not support HSA. The Cisco 7505 has only one RSP slot; therefore, it also does not support the HSA
feature.
The RSP2 ships as Product Numbers RSP2 and RSP2=.
The RSP2 contains most of the memory components used by the system.

1. A system configuration file is contained in NVRAM, which allows the Cisco IOS software to control several system variables.
2. Only Intel Series 2 Flash memory cards can be used with the RSP2.
3. With the RSP2, the HSA feature requires boot ROM Version 11.1(2) or later.
