Figure 22: Firmware Upgrade Mode dialog box 

NOTE:

 The Configuration utility does not resolve the topology of the cell. Therefore, 

firmware upgrades should be made from the central point where the 
BU/DWL-1800B are located. 

The list box on the left-hand side of the dialog box displays the managed units; it is 
sorted sequentially by DWL-1800B followed by DWL-1800R units. 

To upgrade firmware: 

1.  Select the units that you wish to upgrade from the list box. Use 

Shift-click and/or Ctrl-click to select multiple units, or select multiple 
units by dragging with the mouse.   

2.  Specify the firmware file you wish to use in the 

Local file name 

fields; 

there are separate fields for files of different device type. The field text is 
displayed in blue when corresponding unit types are selected in the list 
box. 

3.  In the Remote File Name field, enter the Read/Write community string of the 

unit(s). 

4.  Click 

Advanced

 if you wish to change the settings of the TFTP session 

used in the upgrade download (see  3.2.2.1). 

5.  Click 

Start

 to initiate the firmware upgrade; progress bars are displayed
