Fixing Configuration Errors
If the STATUS LED on the PoS module turns amber and blinks, use the show slot
command to display the configured slot type. The output from this command also
displays information about the module state, including the CARD MISMATCH
message. This message indicates that the slot was previously configured for a module
type different than the one you just installed.
Use one of the following commands to reset the slot configuration:
•
clear slot <slot>
• unconfig slot <slot>
• config slot <slot> module [f32t | f32f | f48t | g4x | g6x | g8x |
g12x | p3c | p12c]
The first two commands listed above clear the slot of a previously assigned
module type. The third command replaces the existing module type configuration
with a new module type configuration.
