This chapter details the updating of the OfficeConnect Remote 840 software. It is divided into the following sections:
The OfficeConnect Remote 840 operational software is stored in the unit's FLASH memory. In order to update the operational software, you must first obtain and copy it to your PC's hard drive. You can then install it into FLASH memory on the OfficeConnect Remote 840.
The method of obtaining the latest versions of the OfficeConnect Remote 840 Operational Software is either via the 3Com website, www.3com.com/ocr840 or via the CD. Install the latest version software from the website or the OfficeConnect Remote 840 CD. Type show system, using the CLI interface, to verify the version software installed on your OfficeConnect Remote 840.
If you have erased the operational software from your OfficeConnect Remote 840, you will need to reinstall the software using a utility on your CD. Follow the procedure described in "Installing Software via DOS".
Once you obtain the OfficeConnect Remote 840 operational software, there are two methods of installing the software into the FLASH memory.
If you have obtained an updated OfficeConnect Remote 840 CD, or if you have erased the copy of the OfficeConnect Remote 840 Operational Software from your hard drive, you need to copy the operational software from the CD to your hard drive.
1 . Insert the OfficeConnect Remote 840 Installation CD in your PC's CD drive.
2 . Click Start > Run.
3 . Type x:\setup.exe (where x is the letter of your CD drive) and click OK to start the OfficeConnect Remote 840 software installation.
Follow the prompts on your screen to finish the software installation. In addition to installing the OfficeConnect Remote 840 operational software, this will also install the utilities, HTML help, and printable documentation.
The OfficeConnect Remote 840 operational software (the *.nac file) included on the CD is copied to your hard drive and not the OfficeConnect Remote 840 unit. It is installed to C:\Program Files\3Com\ocr840.
After you have obtained the operational software using one of the described methods, it will reside on your computer's hard drive in a file with an extension of '.nac' (a NAC file). You can install this software in the FLASH memory of the OfficeConnect Remote 840 using one of the following methods.
Installation of the operational software using the OfficeConnect Remote 840 Manager is a three-part process. First, the current software must be erased from the FLASH memory of the OfficeConnect Remote 840. Once the current software has been erased from the unit you will provide the browser with the pathname of the new NAC file. The browser will then load this file into the unit's FLASH memory. Finally, you will reboot the unit to allow the new operational software to become active.
The software update process does not change configuration of the OfficeConnect Remote 840. However, since a reboot is needed at the end of the process, you should make sure to save the current configuration.
Your browser must support RFC1867 File Upload. This requires Microsoft Internet Explorer version 3.02 (with the file upload add-on installed) or Netscape Navigator 3.0 or higher. You can install Internet Explorer 4 and the file upload add-on from the OfficeConnect Remote 840 Installation CD.
To update the software, go to Tools > Software Update from the OfficeConnect Remote 840 Manager home page. You will be guided through the update process.
When browsing for the update file, select 'All files (*.*)' on the file type pull-down menu.
Your OfficeConnect Remote 840 Installation CD installs a DOS-based utility program onto your hard drive. This utility program, PCSDL.EXE, is invoked by a DOS-batch file, DL.BAT, which has also been installed to your drive.
In order to use PCSDL to load code to your OfficeConnect Remote 840, use the console port straight-through console cable (provided) between your workstation's serial port and the unit's console port.
To update the software from DOS, perform the following:
1 . Using a terminal application such as HyperTerminal to test the serial connection, set up the terminal application with the following settings:
9600 baud, No stop bits, 8-bit characters, no parity
2 . Press Enter on your workstation. If the terminal application displays the OfficeConnect Remote 840> prompt, the serial connection is operational.
3 . Power off your OfficeConnect Remote 840.
4 . Open a DOS window on your workstation.
5 . Change to the directory containing the new operational software. If you obtained the software from the Installation CD or using Instant Update the default directory is c:\Program Files\3Com\ocr840.
The DL.BAT batch file uses the Com 1 port by default. You can change the port used by editing the DL.BAT file. The relevant lines of the file are shown below.
REM
REM Edit the pcsdl command line -v parameter so that it includes
REM the REM version number of the NAC file. The version number of
REM the NAC file is part of the filename. The filename syntax is:
REM
REM vaxxyyzz where xx = major version number
REM yy = minor version number
REM zz = revision number
REM
REM Release 1.0.1 would have a filename of va010001.
REM
REM
REM Change the -p option on the pcsdl command line to use the
REM proper COM port.
pcsdl -p1 -r%BAUDRATE% -vNA1.0.5 -vSD0.1.1 -nSD%2 -nNA%2
6 . Execute the batch file with the following command: dl 115 ms
7 . When Establishing Communications... appears in your DOS window, plug the OfficeConnect Remote 840 back into the outlet.
8 . Wait for the download to complete.
