A note about Legacy and Standard modes:

Modules come configured in STANDARD Mode. Older Gigabit Ethernet modules used the Marvell
ALASKA chipset. This chipset implemented 1000Base-X without clock information and auto
negotiation that is available on newer chipsets. The switch changes internal settings to disable the
clock and auto-negotiation parts of the gigabit signal and ensure compatibility with older Gigabit
Ethernet transceivers

If you find that your system does not function in STANDARD mode, change the mode to LEGACY
and re-test.
