The following sections discuss the ﬁelds on the FLASH DOWNLOAD screen and provide instructions for using them.

Download Method ﬁeld

Use the Download Method ﬁeld to select either the RUNTIME or the BOOTPROM download method. The Reboot after Download ﬁeld appears when the RUNTIME method is used, and the Commit to Flash ﬁeld appears when the BOOTPROM method is used.

The RUNTIME method permanently changes the image in Flash, replacing the currently stored version while the management device is operational. The process neither interrupts network operations nor affects the currently running LM application. When the device is reset, the new image takes effect.

To chose the RUNTIME method:

1.Highlight the Download Method ﬁeld.

2.Toggle from BOOTPROM to RUNTIME, if necessary, using the spacebar.
