Introduction to the BayStack 410-24T Switch

Flash Memory Storage

The following two sections describe switch parameters that are stored in flash memory.

Switch Software Image

Your switch’s software image is stored in flash memory. The flash memory allows you to update your switch software image with a newer version, without changing the switch hardware (see “Software Download” on page 3-102). An in-band connection between the switch and the TFTP load host is required to download the software image.

If a BootP server is set up properly on the network and the BayStack 410-24T switch detects a corrupted software image during the self-test, the switch automatically uses TFTP to download a new software image.

Configuration Parameters

Certain configuration parameters, including the system characteristics strings, some VLAN parameters, IGMP configuration parameters, and the MultiLink Trunk names are stored in flash memory. These parameters are updated every 10 minutes or whenever you issue the Reset command.

Note: Do not power off the switch within ten minutes of changing any configuration parameters, unless you first issue the Reset command. Powering down the switch within 10 minutes of changing configuration parameters (without resetting) can cause the changed configuration parameters to be lost.
