NOTE: If you select the 100 Mb/s or 10 Mb/s display mode, the mode is active for
approximately 5 minutes, at which time the repeater returns to the default
alternating mode.

Automatic Speed Detection

The repeater automatically detects the incoming wire speed of a transmission
and adjusts the repeater's operation accordingly.
The repeater immediately adjusts to 100 Mb/s wire speeds. However, the
repeater requires slightly longer (approximately 8 seconds) to adjust to 10
Mb/s wire speeds.
If you change the NIC wire speed from 10 Mb/s to 100 Mb/s, you must
momentarily disconnect the link for the automatic speed detection function to
work correctly.
During automatic speed detection, 10 Mb/s data on the detecting port will be
invalid (error packets).
The ALTERNATING (default) display mode alternates every 2 to 3
seconds between displaying 10Base-T and 100Base-TX port activity.
