USER’S GUIDE

Port Information

The following settings are available.

Setting	Description
Smart Setting Name	Displays the name of the Smart Setting. The Smart Setting name will
	automatically appear in the text box when selected in the scroll menu.
Smart Setting Type	The topology among switches for a port. Options include:
	• Initiator or Target Port – the default setting. Should be used when there
	are no links between switches.
	• Tree Cascade – designates the port as a tree cascade port. Use this
	setting when connecting multiple switches together in a tree cascade
	configuration. Under most conditions, this setting will result in accept-
	able performance.
	• String Cascade 1 through String Cascade 4 – designates the string
	cascade to which a port is assigned. String cascades maintain fairness
	when two or more InSpeed-based storage switches are serially
	cascaded. Switch performance may be lower when compared to a tree
	cascade configuration.

Pre-Insertion Testing

The following settings are available.

Setting	Description
Enable Policies/Smart	This policy is the default operating mode for all ports and determines what
Insertion	the switch looks for prior to allowing a port to insert into a zone. When the
	policy is enabled, an external device is sent an F7 Initialization notification
	by the switch until an F7 Initialization notification is received from the
	device. Once an F7 Initialization notification is received, the port is
	inserted in the zone.
	This policy takes precedence over all other policies. When this policy is
	disabled, no additional policies are operational, and as long as a port
	transmits a signal of the correct frequency and amplitude, the port will be
	allowed in the zone.
Port Test Before Insertion	This policy ensures a device on a port is a valid, standards-compliant
	participant before allowing the device to be inserted into a zone. The
	device must meet all of the FC-AL requirements along with going through
	a complete change notification cycle. During the change notification cycle,
	the device becomes the Initialization Master (IM) and goes through the
	change notification phases. Once the change notification cycle is
	complete, the device can be inserted. This process ensures a bad device
	is not allowed into the zone.
