For VIC/VWIC compatibility information, refer to the
DSP Optimization on the Cisco 1751 and Cisco 1760 Routers
To find software configuration information for changing the codec complexity of the analog
Voice Interface Cards (VICs) and optimizing the Digital Signal Processor (DSP) resources among
the analog and BRI VICs on the Cisco 1751 and Cisco 1760 routers, refer to
the Cisco 1751 and Cisco 1760
The DSP Calculator tool
for the Cisco 1751 and the Cisco 1760 routers, based on the interface modules selected and their
codec configurations. This tool supports Cisco IOS Software Releases 12.2(8) YN and later.
WIC-1ENET Module
The Cisco WIC-1ENET is a single-port Ethernet interface card supporting 10BASE-T Ethernet. The
card provides the Cisco 1700 Series Router with additional Ethernet interfaces.
The Cisco WIC-1ENET card is only supported on the Cisco 1700 series routers and requires Cisco IOS
Software Release 12.2(2)XJ or later if the card is installed in any WIC slot other than slot 0, or if more
than one card is installed. The card can be used with Cisco IOS Software Release 12.2(4)T, but the card
must be installed in slot 0, and only one Cisco WIC-1ENET card can be installed in the router.
For information on compatibility and hardware/software requirements for the Cisco WIC-1ENET card,
refer to Cisco WIC-1ENET
Identifying the Issue
This section explains what to do to determine the cause of the potential hardware issue(s).
In order to determine the cause, the first step is to capture as much information about the problem as
possible. The following information is essential for determining the cause of the problem:
Console logs - For more information, refer to
Console Connections.
Syslog information - If the router is set up to send logs to a syslog server, you may be able to
obtain information on what happened. For details, refer to the How to Configure Cisco Devices for
Syslog section of
show technical-support command output - The show technical-support command is a
compilation of many different commands including show version, show running-config, and
show stacks. TAC engineers usually ask for this information to troubleshoot hardware issues. It is
important to collect the show technical-support information before doing a reload or power-cycle
as these actions can cause all information about the problem to be lost.
