Section 4: Maintenance of the Access Point

LAPAC1750PRO Access Point Software User Manual

Use the buttons to perform the following tasks:

 

•

Switch: Use the secondary image as the primary image  The change takes 
effect the next time the AP boots  For more information, see Switching 
Firmware Image 

 

•

Upgrade: Upload the specified firmware image to the AP  For more 
information about the firmware upgrade procedures, see Firmware Upgrade 

Click 

Maintenance > Firmware to display the Manage Firmware 

page  From the 

Manage Firmware page, you can:
•  

View the current firmware version for the primary and secondary image

•  

Switch the firmware image running on the AP.

•  

Upload a new firmware version.

Switching Firmware Image

The AP always tries to boot with the primary image  If the primary image fails to 
load, then the secondary image is used to boot the AP  Whenever such a failover 
occurs, the system creates a log message to help you troubleshoot the firmware 
failure 

Use the following steps to switch the firmware image running on the AP:

1  

Click Switch 

A dialog box displays confirming the firmware image switch and subsequent 
reboot 

2  

Click OK to proceed 

The process may take several minutes during which time the access point will 
be unavailable  Do not power down the access point while the image switch is 
in process  When the image switch is complete, the access point restarts  The AP 
resumes normal operation with the same configuration settings it had before 
the upgrade 

Firmware Upgrade

As new versions of the access point firmware become available, you can 
upgrade the firmware on your devices to take advantage of new features and 
enhancements  The AP uses a TFTP client for firmware upgrades  You can also 
use HTTP to perform firmware upgrades 

After you upload new firmware and the system reboots, the newly added 
firmware becomes the primary image  If the upgrade fails, the original firmware 
remains as the primary image 

NOTE:

When you upgrade the firmware, the access point retains the existing 
configuration information 

Use the following steps to upgrade the firmware on an access point by using 
TFTP:

1  

Select TFTP for Upload Method 

2  

Enter a name (1 to 256 characters) for the image file in the Image Filename 
field, including the path to the directory that contains the image to upload  
For example, to upload the ap_upgrade tar image located in the /share/
builds/ap directory, enter /share/builds/ap/ap_upgrade tar in the New 
Firmware Image field The firmware upgrade file supplied must be a  tar file  
Do not attempt to use  bin files or files of other formats for the upgrade; 
these types of files will not work 

3  

Enter the IP address of the TFTP server  

4  

Click Upgrade 

Upon clicking Upgrade for the firmware upgrade, a popup confirmation 
window is displayed that describes the upgrade process
