D-Link DSR-Series User Manual 200
Section 9 - Maintenance
You can upgrade to a newer rmware version from the Administration web page. In the Firmware Upgrade
section, to upgrade your rmware, click Browse, locate and select the rmware image on your host, and click
Upgrade. After the new rmware image is validated, the new image is written to ash and the router will
automatically reboot with the new rmware.
Universal Firmware (FW) Naming Convention: The new rmware naming convention is DSR_<Model
name>_<Hardware>x_FW <Version number>_<WW or RU>. For all the same hardware (A, B, C, etc.), there will
be only one Firmware le which is to be used with all the versions (1, 2, 3, etc.) of the respective hardware. For
example, the new FW le name is DSR_250_Ax_FW3.12_WW. This FW le can be used for FW upgrade of the
following hardware versions: A2, A3, A4, and so on.
Warning: During the rmware upgrade, do NOT try to go online, turn o the DSR, shut down your PC, or interrupt the
process in anyway until the operation is complete. This should take only a minute or so including the reboot process.
Interrupting the upgrade process at specic points when the ash is being written to may corrupt the ash memory
and render the router unusable without a low-level process of restoring the ash rmware (not through the web GUI).
