LOCAL MANAGEMENT

The Reboot after Download ﬁeld appears by default when the RUNTIME method is used. If YES is selected, the MicroMMAC-T will automatically reset after the image is downloaded into Flash to load the new image into the active system ﬁle.

You can choose to use the BOOTPROM method also. It forces the device to reset and reboot from the download server rather than from the image stored in Flash.

To choose the BOOTPROM method:

1.Highlight the Download Method ﬁeld

2.Toggle from RUNTIME to BOOTPROM using the spacebar.

When BOOTPROM is selected, the Commit to Flash toggle ﬁeld appears, replacing the Reboot after Download ﬁeld. If YES is chosen, the device will automatically replace the old image in Flash with the new image. If NO is chosen, the new image will be downloaded into active memory only, leaving the prior image in Flash unaffected and available for use at next reset. The NO option allows the user to test a new system ﬁle without losing the prior system ﬁle.
