Software and Hardware Requirements
The 4R port adapter on a VIP2-15 or VIP2-40 installed in a Cisco 7000 series or Cisco 7500 series router
requires that the host router is running Cisco IOS Release 11.1(472) or later, Cisco IOS Release
11.1(9)CA or later, Cisco IOS Release 11.2(1) or later, or Cisco IOS Release 11.2(6)P or later.
The 4R port adapter installed in a Cisco 7204 or Cisco 7206 requires that the host router is running Cisco
IOS Release 11.1(472) or later, Cisco IOS Release 11.1(9)CA or later, Cisco IOS Release 11.2(1) or
later, or Cisco IOS Release 11.2(6)P or later.
The 4R port adapter installed in a Cisco 7202, requires that the host router is running Cisco IOS
Release 11.1(19)CC1 or later, or Cisco IOS Release 11.3(4)AA or later.
In the Cisco 7000 series or Cisco 7500 series routers, the 4R port adapter requires the following VIP2
models:
• VIP2-15 (1 MB of SRAM, 8 MB of DRAM)
• VIP2-20 (1 MB of DRAM, 16 MB of SRAM)
• VIP2-40 (2 MB of SRAM, 32 MB of DRAM)
Caution To prevent system problems, the VIP2 requires that the Cisco 7000 series router has the 7000 Series
Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI) installed. The VIP2
will not operate properly with the Route Processor (RP), Switch Processor (SP), or Silicon Switch
Processor (SSP) installed in the Cisco 7000 series router.
Note The minimum recommended VIP2 model is a VIP2-15.
