Appendix A: Flash Upgrades
You can use the APC KVM switch flash upgrade feature to update the KVM switch with the latest
firmware available. This update can be performed using the Network Access Software or using a
Trivial File Transfer Protocol (TFTP) target device.
After the flash memory is reprogrammed with the upgrade, the KVM switch performs a soft reset,
which terminates all KVM server module sessions. A target device experiencing a KVM server
module firmware update might not be visible or might be listed as disconnected. The target device
opens normally when the flash update is completed. During an OSD initiated upgrade, the KVM
server module status indicator in the OSD Main window is yellow.
To upgrade the KVM switch firmware using the web interface:
2.
Connect a computer running terminal emulation software to the configuration port on the rear
panel of the KVM switch using a straight serial cable. The terminal should be set to 9600 bps,

Tun on the KVM switch. After approximately one minute, press any key to access the Console
Main menu.

subsystems.

Repairing damaged firmware
If the firmware is damaged after a firmware upgrade (for example, if the KVM switch is turned off
and turned on during the upgrade process), the KVM switch will remain in boot mode. In this
mode, the Power LED at the rear panel flashes at about 1 Hz, and the KVM switch attempts to
restore the firmware over TFTP using the following default configuration:
