MWAM Problem Solving
MWAM Problem Solving
In a typical MWAM problem solving situation, you would first check the following:
• The module is firmly seated in its slot.
• The installation is verified.
• The STATUS LED is on.
• The version of Cisco IOS software that supports the MWAM is installed.
• The MWAM configuration is verified.
This section also contains information that can be useful for some common problems that may affect the
proper operation of the MWAM, such as:
• DIMM Issue
• Performance Tuning
• Buffer Allocation for Complex 0 CPUs
Module Seating
Note All Catalyst 6500 series switches and Cisco 7600 series internet routers support hot swapping, which
lets you install, remove, replace, and rearrange the modules without turning off the system power. When
the system detects that a module has been installed or removed, it runs diagnostic and discovery tests
automatically, acknowledges the presence or absence of the module, and resumes system operation with
no operator intervention. However, DO NOT remove the MWAM until it has shut down (see the
“Front-Panel Features” section on page 1-3 and the “MWAM Shutdown” section on page 1-4 for
details).
To ensure the MWAM is securely seated, see the “MWAM Installation” section on page 3-3.
Verify the installation
Note As a rule, right after installing the MWAM, you verify the installation of the MWAM.
To verify the installation of the MWAM, see the “Verifying the Installation” section on page 3-9.
STATUS LED
Verify that the MWAM STATUS LED is on. Periodically, check the STATUS LED. If the STATUS LED
changes to orange or red, the MWAM has not successfully completed the boot process or may have
encountered an error. For more information about the orange or red STATUS LED states, see Table 1-1
on page 1-3.
