Chapter 7. The Firmware Upgrade Utility
Note: 1. The upgrade to the KVM Adapter Cables takes place via the Cat
5e/6 cable that connects the adapter cable to the KVM switch, so
there is no separate firmware upgrade cable to attach.
2. Adapter cable firmware selected with the upgrade utility will
upgrade in a single session all connected adapter cable models
that match the firmware type.
