2-2 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.
