Configuring the Director enables the port to process 2K frames from attached devices. If this option is not enabled, the port uses the BB_Credit (1-60) configured through the Operating Parameters dialog box. If a device is connected and logged in to the fabric when extended distance is enabled or disabled on the corresponding port, the switch will send OLS for 5 ms to force the device to log in again and obtain the new BB_Credit value set for the port. • LIN Alerts-A link incident (LIN) is a problem detected on a fiber optic link, such as the loss of light or invalid sequences. When a problem occurs, a LIN alert is sent to the Link Incident Log in the switch Product Manager. LIN alerts warn you that there is a link incident being detected through a port connection. Place or remove check marks in the check boxes in this column to enable or disable link incident alerts. The factory default is to enable LIN alerts. A link incident causes a yellow attention indicator (triangle) to display for the port in the Hardware View, Port Card View, and in the alert column of the Port List View. Once a LIN occurs, you must acknowledge it by choosing the Clear Link Incident Alert option from the right-click menu for the port (Hardware View). A description of the alert displays in the Link Incident field of the Port Properties dialog box (refer to Figure 2-11 on page 2-17). If the check boxes in this column are not selected, no link incident indicators display in the Hardware View. Also, the Link Incident field of the Port Properties dialog box is blank and a link incident is recorded in the Link Incident Log. LINs are always logged in the Link Incident Log, regardless of the configuration. If LIN Alerts are enabled, you can receive e-mail notification when a LIN occurs. To receive e-mail notification, you must configure and enable this feature in the Maintenance menu of the StorageWorks HA-Fabric Manager (HAFM) and enable e-mail notification through the Enable E-Mail Notification option in the Product Manager's Maintenance menu. For additional information about LIN alerts, refer to "Link Incident Alerts" on page 2-44. • Type-Choose each port's type (G_Port, E_Port, or F_Port) in this column from the drop-down list. NOTE: In S/390 mode, you cannot change port types unless the optional SANtegrity feature is installed. If ports are configured as E_Ports in Open Systems mode, and you install SANtegrity before changing to S/390 mode, the ports will remain as E_Ports when you change to S/390 mode. If SANtegrity is not installed, setting a director to S/390 mode will change all E_ports to G_Ports. 3-10 director product manager user guide
