Software and Hardware Requirements
Software and Hardware Requirements
Table 2-1 lists the recommended minimum Cisco IOS software release required to use the PA-2CE1in
supported router or switch platforms.
For configuration guidelines on port adapters in the Cisco 7200 series, refer to the Cisco 7200 Series
Port Adapter Hardware Configuration Guidelines.
Checking Hardware and Software Compatibility
To check the minimum software requirements of Cisco IOS software with the hardware installed on your
router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether
modules within a system are compatible, but it does provide the minimum IOS requirements for
individual hardware modules or components.
Note
Access to this tool is limited to users with Cisco.com login accounts.
To access Software Advisor, click Login at Cisco.com and go to Technical Support Help—Cisco TAC:
Tool Index: Software Advisor. You can also access the tool by pointing your browser directly to

software release needed for your hardware.

The
PA-2CE1 can be used in the VIP2 in all Cisco 7500 series routers using a Route Switch Processor (RSP), and in Cisco 7000 series routers using
the RSP7000 and RSP7000CI.
3.
The specific VIP2 models recommended for the PA-2CE1s are VIP2-40(=), which has 2 MB of SRAM and 32 MB of DRAM, and VIP2-50(=), which
has 4 to 8 MB of SRAM and 32 to 128 MB of SDRAM. The VIP2-40 and VIP2-50 support two installed PA-2CE1s that are running ISDN PRI with
distributed services or channelized E1 with distributed switching or distributed services. The VIP2-20=, which has 1 MB of SRAM and 16 MB of
DRAM, supports two installed PA-2CE1 that are running ISDN PRI or channelized E1 with distributed switching. The VIP2-15(=), which has 1 MB
of SRAM and 8 MB of DRAM, supports one installed PA-2CE1 that is running ISDN PRI or channelized E1 without distributed switching.
4.
Cisco 7000, Cisco 7500, and Cisco 7200 series routers support up to five installed PA-2CE1 that are running ISDN PRI (ten E1 ports total, including
E1 ports on MultiChannel Interface Processors installed in Cisco 7000 series or Cisco 7500 series routers). There are no such limitations when
installed PA-2CE1s are running channelized E1.
