2-2
Software and Hardware Requirements
lists the minimum Cisco IOS software release required to use the PA-4T+ port adapter in supported
router platforms.
1
For PA-4T+ port adapters installed in Cisco 7200 series routers, Cisco IOS Release 11.1(6)CA, or later, is required; however, we recommend Cisco IOS
Release 11.1(8)CA or later.
Note Cisco IOS Release 11.2(7a)P or later supports half-duplex and binary synchronous
communications (Bisync) operation on PA-4T+ port adapters in Cisco 7200 series routers.
Also refer to the Cisco IOS software release notes for the Cisco IOS software version you are
running.
In Cisco 7000 series or Cisco 7500 series routers, the PA-4T+ requires the following VIP2 models:
• VIP2-15(=) (1 MB of SRAM, 8 MB of DRAM)
• VIP2-20(=) (1 MB of SRAM and 16 MB of DRAM)
• VIP2-40(=) (2 MB of SRAM, 32 MB of DRAM)
• VIP2-50(=) (4 to 8 MB of SRAM, 32 to 128 MB of DRAM)
Note The PA-4T+ can be installed in port adapter slot 0 or slot 1 on the VIP2 motherboard, or in
any available port adapter slot in a Cisco 7200 series chassis.
Caution To prevent system problems, the VIP2 requires that Cisco 7000 series routers have the
RSP7000 and RSP7000CI installed. The VIP2 will not operate properly with the Route Processor
(RP), Switch Processor (SP), or Silicon Switch Processor (SSP) installed in a Cisco 7000 series
router.
