Software and Hardware Requirements
Software and Hardware Requirements
The PA-MC-T3-EC and PA-MC-2T3-EC require Cisco IOS Release 12.4(11)T
a later release of Cisco IOS Release 12.4T.
The PA-MC-T3-EC and PA-MC-2T3-EC are supported on the Cisco 7301 router, the Cisco 7201 router,
the Cisco 7204 VXR and Cisco 7206 VXR routers with the NPE-G1 and NPE-G2.
Additionally, the PA-MC-T3-EC and PA-MC-2T3-EC are supported on the Port Adapter Jacket Card in
the Cisco 7204 VXR and Cisco 7206 VXR routers.
For configuration guidelines on port adapters in the Cisco 7200 VXR routers, refer to the
Series Port Adapter Hardware Configuration
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 Cisco 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 Support > Tools and Resources >
Software Advisor. You can also access the tool by pointing your browser directly to
http://www.cisco.com/en/US/support/tsd_most_requested_tools.html.
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-T3-EC 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-T3-EC.
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, see the
Coaxial Attenuator on Cisco Port Adapters
