Figure 3-54. Firmware Upgrade Setup—Option 2
(TFTP Server and Firmware File on Remote Server)
NOTE: The LAN and COM1 ports share a common data channel when
loading firmware over-the-air. Transferring the radio firmware
image file (≈ 3 Mb), may take several minutes depending on
traffic between the TFTP server and the transceiver.
Regardless of your connection to the transceiver, loading firm-
ware/configuration files into the unit’s flash-RAM is much
slower than loading software onto a PC hard drive or RAM.
Upgrade Procedure To load a new firmware file (filename.ipk) into the transceiver, use the
following procedure:
1. Launch a TFTP server on a PC connected either directly or via a
LAN to the Ethernet port (
LAN) of the radio. Point the server
towards the directory containing the firmware image file.
2. Connect to the Management System by whichever means is conve-
nient: Browser or Telnet via the
LAN, or Terminal emulator via the
COM1 port.
3. Go to the MS Reprogramming Menu.
(Main Menu>>Maintenance Menu>>Reprogramming Menu)
4. Fill in the information for the:
•
TFTP Host Address—IP Address of server (host computer) run-
ning TFTP server.
•
Retrieve File—Name of file (filename.ipk) to be pulled from the
TFTP server holding the firmware file.
