Installing the Adapter
1. Set the adapter Operating Mode Jumper (J7) for Single (1x) or
Multi-Drive (5x) operation (see
below). For complete details on Multi-Drive mode operation, see
.
Figure 2.1 Setting Single/Multi-Drive Operation and Node Address Switches
2. Set the adapter node address by rotating the Node Address Switches
to the desired value for each digit.
Important: Each node on the network must have a unique address.
The node address must be set before power is applied
because the adapter uses the node address it detects
when it first receives power. To change a node address,
you must set the new value. Then remove and reapply
power to the adapter, or reset the adapter.
The node address switch settings can be verified using a PowerFlex
4-Class HIM, DriveExplorer, or DriveExecutive to view Diagnostic
Item number 28 (listed on
).

Important: In this mode, connections to multiple drives must be
removed since all powered and connected hosts will respond to
any message sent by the adapter.

drives. DSI peripherals (22-HIM-*, 22-SCM-*, etc.) do not
operate with the adapter in this mode.
