Note 3:
When updating the firmware, the factory-default MAC address is used rather than the
user-defined MAC address. Thus, the MAC address (user-defined) displayed in the firmware
update window may not be the one required. If this is the case, the factory-default MAC address
should be manually entered into the MAC Address field, or restore the MAC address to the
factory-default settings via the web configuration pages.
Note 4:
The "BOOTPREQ from MAC: xx-xx-xx-xx-xx-xx" message indicates there is a module with
the factory-default MAC address "xx-xx..." that is asking for the firmware to be updated. The
update process will not begin if you assign a user-defined MAC address in the firmware update
window, since the addresses do not match. If this situation occurs,repeat the update procedure
and manually enter the factory-default MAC address in the firmware update window, as
described in Step 5 on Page 6.The firmware update procedure is illustrated in the figure below.
Note 5:
BOOTP (Bootstrap Protocol) is defined in RFC-951 and uses UDP ports 67 and 68.
Note6:
TFTP (Trivial File Transfer Protocol) is defined in RFC-1350 and uses UDP port 69.
