Flash Memory Storage

The BayStack 350 switch uses flash memory to store the switch software image. Flash memory allows you to update the software image with a newer version without changing the switch hardware. An in-band connection between the switch and the TFTP load host is required to download the software image (refer to “Software Download” on page 3-48). For information about connecting a console terminal for this procedure, refer to “Service Port Cabling” on page 3-2.

If a BootP server is set up properly on the network and the BayStack 350 switch detects a corrupted software image during the self-test, the switch automatically uses TFTP to download a new software image.

BootP Automatic IP Configuration

The BayStack 350 switch has a unique 48-bit hardware address, or media access control (MAC) address, that is printed on a label on the back panel. You use this MAC address when you configure the network BootP server to recognize the BayStack 350 switch BootP requests. A properly configured BootP server enables the switch to automatically learn its assigned IP address, subnet mask, IP address of the default router (default gateway), and software image file name. Refer to Appendix D, “Sample BootP Configuration File,” for an example of a BootP configuration file.
