The new fabric will contain four zones for this zone type. When the two fabrics are
connected, the result will have zone 1 from both fabrics combined in zone 1, zone
2 will have the ports defined for the original fabric A, zone 3 will contain the
original ports defined for zone 3 of fabric B, and zone 4 will contain the ports
defined in the original zone 2 of fabric B.
Credit Chaining
Credit chaining is performed internally on a switch. The only ports that can
provide credit chaining are main credit chain ports 1 & 5 (8-port switch), and ports
1, 5, 9, and 13 (16-port switch).
To perform credit chaining, additional port(s) must be designated as donors to the
main credit chain port.
Donor Ports
Each of the three ports that follow a main credit chain port (in sequential port
number order) can be designated as a donor port. The donor ports are defined in
sequential order as the number of extended credits are requested. For an additional
8-credit value to add to the current port, select the F_Ext16 selection. For 16
additional credits, select F_Ext24. For an additional 24 credits, select F_Ext32. For
each additional 8 credits added to the main credit chain port, an additional sequen-
tial port is rendered unusable by another type of port connection.
Ports designated as donor ports are no longer able to communicate with external
devices physically attached to that port. These devices must be moved to another
non-donor port.
Selecting a Main Credit Chain Port for Extended Credits
Either right click on the desired main credit chain port in any faceplate and select
the desired extended credit selection (F_Ext), or, from the View>Port Modes
faceplate screen, click through the port types for the desired main credit chain port
until the desired extended credit selection is displayed.
After specifying the desired number of credits, press the Apply button. The
Logged-In LED for each donor port will light on the switch. When viewing the
port mode faceplate display, the main credit chain port changed to an F_Port and
each donor port displays the appropriate F_Ext label for their level of chained
credits.
