Switch ports can be configured as:
• F_Ports to provide direct connectivity for switched fabric devices.
• 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

The switch provides a modular design that enables quick removal
and replacement of FRUs, including:
• Redundant power supplies and cooling fans. The switch provides
two power supplies, each with an AC power receptacle and three
cooling fans (six fans total).
• Up to 24 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 4500 Fabric Switch can be purchased at a discount price
with the Flexport Technology feature. The switch is delivered with only eight
ports enabled. When additional port capacity is required, the remaining ports
are enabled (in eight-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.
