McDATA StorageWorks 2/140 - Director Switch Planning Manual page 43

Switch ports can be configured as:
• Fabric ports (F_Ports) to provide direct connectivity for switched
fabric devices.
• Fabric loop ports (FL_Ports) to provide switched arbitrated loop
connectivity and fabric attachment for FC-AL devices. The switch
supports:
— Connectivity of public loop devices and private loop devices.
Refer to Public Versus Private Devices
— Configuration of public arbitrated loops and private
arbitrated loops. Refer to
information.
• E_Ports to provide ISL connectivity to fabric directors and
switches. E_Port connectivity is not standard and must be
configured through the optional full fabric product feature
enablement (PFE) key. Refer to
The switch provides a modular design that enables quick removal
and replacement of FRUs, including up to 12 duplex SFP fiber-optic
port transceivers. Shortwave laser transceivers are available for
transferring data over multimode fiber-optic cable. Longwave laser
transceivers are available for transferring data over singlemode
fiber-optic cable. Fiber-optic cables attach to switch port transceivers
with duplex LC connectors.
NOTE: The Sphereon 4300 Fabric Switch can be purchased at a discount price
with the Flexport Technology feature. The switch is delivered with only four
ports enabled. When additional port capacity is required, the remaining ports
are enabled (in four-port increments) through purchase of a PFE key.
The switch front panel provides a combined initial machine load and
reset (IML/RESET) button, Ethernet LAN connector, port status
LEDs, port speed LEDs (green for 1.0625 Gbps operation and blue for
2.1250 Gbps operation), green power (PWR) LED, and amber system
error (ERR) LED.
The switch rear panel provides a 9-pin DSUB maintenance port for
connection to a local terminal or remote terminal. Although the port
is typically used by authorized maintenance personnel, operations
personnel can use the port to configure switch network addresses.
