8.0 UPGRADING LEDR FIRMWARE
8.1 Introduction
The LEDR radio’s firmware can be upgraded with new software
releases that may be issued from time-to-time by Microwave Data Sys-
tems. To support firmware upgrades while the radio is in use, the LEDR
radio contains two complete copies of its firmware. Once the inactive
version is replaced, the radio can be rebooted using the code in the new
firmware. However, if an error occurs during the download, the radio
can easily recover because it always has a complete copy of firmware
available.
NOTE: Any time new firmware is loaded into a radio, it must be power
cycled. Merely rebooting a radio will not guarantee proper
operation with the new firmware.
Firmware reprogramming can be done using one of three methods:
1. Locally through the front panel
CONSOLE Port .
2. Locally using TFTP and Telnet through the
ETHERNET Port .
3. Remotely over a network connection using TFTP and Telnet to the
ETHERNET Port .
The procedures that follow use one or both of two utilities found in
MDS’ LEDR Utilities package. These utilities will facilitate local and
remote transferring of firmware files to and from the LEDR radio. These
applications are available from Microwave Data Systems on floppy disk
(P/N 03-3631A01) or on the FTP section of the MDS Internet site at
www.microwavedata.com.
The following sections will explain how to program new firmware into
the radio using each of the three connection options. They assume the
LEDR Utilities are installed on each computer system named in the pro-
cedure.
NOTE: The ETHERNET, SERVICE CHANNEL and CONSOLE Ports
share a common data channel when loading firmware
over-the-air. Transferring the radio firmware image file (≈ 1
MB), may take up to 30 minutes if there is other activity on any
of the other ports.
Regardless of your connection to the LEDR radio, loading
data/firmware into the radio’s SRAM is much slower than
loading software onto a PC hard drive or RAM.
