more often than is absolutely necessary.
Procedure
Step 1 Grasp the module on the sides, and insert it into the switch slot until you feel the connector snap into place.
Step 2 Insert an appropriate cable into the module port. Insert the other cable end into the other device.
Verifying Port Connectivity
After you connect the switch port and another device, the port LED turns amber while the switch establishes a link. This process
takes about 30 seconds, and then the LED turns green. If the LED turns off, the target device might not be turned on, there might be
a cable problem, or there might be a problem with the adapter installed in the target device.
