10.9 DOWNLOADING A SOFTWARE UPGRADE
You can upgrade the operational software in the switch without physically opening the switch or
being in the same location. The software storage sector in the flash memory of the switch is
reprogrammed, allowing you to easily download software feature enhancements and problem fixes
to the switch from a local or remote location.
Software can be downloaded to the switch in two ways:
•
Via the serial port. This procedure is an out-of-band operation that copies the software through
the serial port to the switch. This operation takes approximately three minutes and requires
minimal configuration.
•
Via TFTP download. This procedure uses a TFTP server connected to the network and
downloads the software using the TFTP protocol. A TFTP download is much faster than a serial
download, requiring only a few seconds, and can be used to upgrade a switch that is not
physically in the area. The disadvantage is that this method requires a TFTP server and
additional setup.

of equipment and configuration.
