Installing the New Firmware
1. From the Select Firmware Version drop‑down list (see figure 70,

PREPARE0%. As it writes the upgrade to flash, the status changes incrementally to
PREPARE100%.
3. Click forward. The Device Upgrade Status changes to READYTOACTIVATE.

) to activate the upgrade and move to the
READYTOCOMMIT state.
b. Click reverse (see figure 70,
5
) to abandon the upgrade using the BACKOUT state.
5. Once the device is in the READYTOCOMMIT state:
a. click forward (see figure 70,
4
) to irrevocably commit to the upgrade using the
COMMITTING state.
b. click reverse (see figure 70,
5
) to return to the original firmware and the
READYTOACTIVATE state.
6. The unit reboots. Once the reboot is complete, the device upgrade process is complete
and the device enters the WAIT state.
