Checking Hardware and Software Compatibility
For configuration guidelines on port adapters in the Cisco 7200 series, refer to the
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.

Choose a product family or enter a specific product number to search for the minimum supported
software release needed for your hardware.
75-Ohm In-Line Coaxial Attenuator
A 75-ohm in-line coaxial attenuator may be required to tune the signal between the PA-MC-2T3+ and
the far-end equipment, if the port adapter is experiencing line code violations (LCVs). LCVs occur when
the far end equipment transmit signal saturates the front end receiver of the PA-MC-2T3+.
Cisco offers an attenuator kit (ATTEN-KIT-PA=) that contains five attenuators with fixed values ranging
from 3-dB to 20-dB. For more information on the attenuator kit go to the following website:
