ERMINATION ONFIGURATION
Internal termination on Logic Component is always on by default and is not
settable at the point of the logic components (see Figure 5-1). To ensure proper
termination when configuring the switch termination, always have the termination
enabled at the specified alphanumeric port and the termination disabled at the
specified numeric port.
Example:
Host adapter is connected to port 1 (port 1 termination disabled) target device
connected to port A (port A termination enabled), with port A1 enabled through
the switch (see Figure 5-1).
