Installing the Adapter
Setting the MAC Address
Set the MAC address using the MAC Address switches (
Refer to
Table 2.A
for specific MAC address switch settings.
Important: Each node on the network must have a unique MAC
address. Set the MAC address before power is applied
because the adapter uses the MAC address it detects when it
first receives power. To change a MAC address, you must
set the new value. Then remove and reapply power to (or
reset) the adapter.
