Installing the Adapter
Setting the MAC Address
Set the MAC address using the MAC Address switches (
Figure 2.1
).
Refer to
Table 2.A
for specific MAC address switch settings.
Important: Each node on the network must have a unique MAC
address. The MAC address must be set 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
the adapter, or reset the adapter.
