Line modules and SRP modules have two recessed buttons that enable you to reset the software or module. You can use the NMI button to reset the software on the module and the module reset button to reset the module. See Figure 5.
If a line module fails to respond for an extended time, a software problem might exist with that module. You can depress the NMI button with a paper clip to suspend the current software task. Depending on the situation, this action might also reset the software on the module.
If depressing the software reset button fails to correct the issue with the line module, depress the module reset button. This action reboots the line module.
The buttons work in the same way for the SRP module. Depressing the module reset button on an SRP module is equivalent to rebooting the router and causes all the line modules to reboot.
