– Download a New Image Using the Bootloader CLI
Because the CLI option requires a physical connection to the unit's serial port, Proxim recommends the ScanTool
option.
Download a New Image Using ScanTool
To download the AP Image, you will need an Ethernet connection to the computer on which the TFTP server resides and
to a computer that is running ScanTool (this is either two separate computers connected to the same network or a single
computer running both programs).
ScanTool detects if an Access Point does not have a valid software image installed. In this case, the TFTP Server and
Image File Name parameters are enabled in the ScanTool's Change screen so you can download a new image to the
unit. (These fields are grayed out if ScanTool does not detect a software image problem.)
Preparing to Download the AP Image
Before starting, you need to know the Access Point's IP address, subnet mask, the TFTP Server IP Address, and the AP
Image file name. Make sure the TFTP server is running and configured to point to the folder containing the image to be
downloaded.
Download Procedure
Follow these steps to use ScanTool to download a software image to an Access Point with a missing image:
1. Download the latest software from http://support.proxim.com.
1. Copy the latest software updates to your TFTP server.
2. Launch ScanTool.
3. Highlight the entry for the AP you want to update and click Change.
4. Set IP Address Type to Static.
NOTE: You need to assign static IP information temporarily to the Access Point since its DHCP client functionality is not
available when no image is installed on the device.
5. Enter an unused IP address that is valid on your network in the IP Address field. You may need to contact your
network administrator to get this address.
6. Enter the network's Subnet Mask in the field provided.
7. Enter the network's Gateway IP Address, if necessary. You may need to contact your network administrator to get
this address. You should only need to enter the default gateway address (169.254.128.133) if the Access Point and
the TFTP server are separated by a router.
8. Enter the IP address of your TFTP server in the field provided.
9. Enter the Image File Name (including the file extension). Enter the full directory path and file name. If the file is
located in the default TFTP directory, you need enter only the file name.
10.Click OK.
The Access Point will reboot and the download will begin automatically. You should see downloading activity begin
after a few seconds within the TFTP server's status screen.
11. Click OK when prompted that the device has been updated successfully to return to the Scan List screen.
12.Click Cancel to close the ScanTool.
13.When the download process is complete, configure the AP.
Download a New Image Using the Bootloader CLI
To download the AP Image, you will need an Ethernet connection to the computer on which the TFTP server resides.
This can be any computer on the LAN or connected to the AP with a cross-over Ethernet cable.
