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 for information.
— Configuration of public arbitrated loops and private
arbitrated loops. Refer to Public Versus Private Loops for
information.
• E_Ports to proved ISL connectivity to fabric directors and
switches.
The switch provides a modular design that enables quick removal
and replacement of FRUs, including:
• Redundant power supplies and cooling fans. The switch is
delivered with one external power supply assembly, and a second
power supply can be installed as an option. When a second
power supply is detected, the switch automatically enables high
availability (HA) mode. Three internal cooling fans provide
airflow.
