A. Yes, if the target Flash card does not have enough free space for the store of the new modem image, SWIM erases the target Flash. SWIM does not erase the Flash card if: • the upgrade of the system software does not occur within the same job as the modem upgrade. • the target Flash partition for the modem upgrade contains the current system software image. Instead, SWIM prevents the modem upgrade on that Flash partition. On the Cisco AS5200, the bootflash card stores modem images, which can contain the bootloader image that currently runs. If there is not enough free space to contain the new modem image, SWIM erases the bootflash card. Back up and restore bootloader images in the case that an erase of the bootflash is necessary for the upgrade of the modem image. SWIM issues a verification warning if SWIM needs to erase the bootflash.
