Only one QAM24 can be updated at a time.
QAM24 does not automatically reset after the new SW is downloaded. It must be
manually reset by depressing the recessed reset button on the front of the card.
To perform the SW update, first access the QAM command as shown in Figure 52 in Section
6.14. At the bottom of the page are the fields necessary for the SW upgrade (Figure 53). Figure
58 below shows those fields filled in as an example upgrade.
The “tftpIP” will be the IP address of the device that contains the upgrade file (your PC). The
“Filename” will be the name of the upgrade file (e.g. “QAM24_01.05.03.img”). It is
recommended that you retain the original filename of the update file you have been issued to
avoid confusion later on. The reset field only causes a soft reset. The card needs a hard reset
after the new SW is loaded.
