What should be done after installing a module in a switch?

After installing a module in a switch, verifying that the STATUS LED is lit is an important step to ensure that the module has been successfully installed and is operational. The STATUS LED provides immediate visual feedback about the module's functionality. A lit STATUS LED typically indicates that the module is powered on and functioning correctly, while an unlit or blinking LED may signify issues such as improper installation, a malfunctioning module, or a power supply problem.

Checking the STATUS LED is a standard procedure in network device management because it allows technicians to quickly assess the status of the hardware without needing to conduct more complex troubleshooting steps. This simple check can save time and help ensure that the switch is up and running smoothly with the newly installed module integrated into the network.

Other options, while they may seem reasonable in certain contexts, do not represent the immediate action that should be taken following module installation. For example, checking the power supply voltage might be relevant if there are issues, but it is not a standard immediate post-installation step. Similarly, rebooting the switch or removing other modules would unnecessarily disrupt the system and may not be required if the installation was successful. Thus, confirming the STATUS LED provides a straightforward and effective way to ensure the module is ready for use.
