SCAN Mode
SCAN Mode is indicated by a flashing CPU port LED. The switch scans to either port with a CPU powered-ON. That port remains
active for the configured dwell time (default time is 5 seconds) before switching to the other powered-ON CPU port. See
COMMAND MODE Section for configuring the scan dwell time.
NOTE: The keyboard and mouse must remain idle for the full SCAN dwell time before the switch selects the other port.
BROADCAST Mode
(USE WITH EXTREME CAUTION)
BROADCAST Mode is indicated when both CPU LEDs are illuminated. This mode allows the operator to send keystrokes to both
active CPUs simultaneously. However, BROADCAST Mode has some critical requirements:
1. BROADCAST Mode must be OFF when booting an attached CPU.
2. COMMAND Mode must be OFF for keystrokes to reach attached CPU(s) when in BROADCAST.
