6 Managing and Maintaining D-Link Access Points Table 19. AP Upgrade Field File Name Group Size Managed AP Description Enter the name of the upgrade file. You may enter up to 32 characters, and the file extension ".tar" must be included. When you upgrade multiple APs, each AP contacts the TFTP server to download the upgrade file. To prevent the TFTP server from being overloaded, you can limit the number of APs to be upgraded at a time. In the Group Size field, enter the number of APs that can be upgraded at the same time. When one group completes the upgrade, the next group begins the process. The combination box lists the APs that the switch manages. Each AP is identified by its MAC address and location (if specified). To upgrade one or more APs, select the AP MAC address from the list. To upgrade all APs, select "All" from the top of the list. The Group Size field limits the number of simultaneous AP upgrades in order not to overwhelm the TFTP server. NOTE: We recommend that you upgrade all managed APs at the same time. After you provide the information about the upgrade file, click Start to begin the upgrade process. Additional fields appear to provide information about upgrade status and success. The software download could be aborted while the code transfer is in progress for any AP only during the time the Abort button is displayed. It still completes the download from the TFTP server, but does not update its NVRAM. Once the NVRAM update begins for all APs involved, the Abort button disappears. An activity/progress bar is displayed during the upgrade. The activity bar is no longer displayed once the upgrade process is complete, that is, the AP is up and running and managed. Figure 55.
