Pre-Insertion Testing

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 acceptable 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.

Setting Description

Enable Policies/Smart

Insertion

This policy is the default operating mode for all ports and

determines what 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 that 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 that a bad device is not allowed into

the zone.
