Major Fibre Channel port features include:

•

Each Switch chassis has 16 Fibre Channel ports. Each port operates at 
1062.5 megabaud.

•

Any or all 16 ports may be: 

Fabric ports connect to fibre channel public devices and device 

loops. A fabric port is self configuring as an F_Port for a public device 
or as an FL_port for a loop of public devices. Refer to 

. 

Segmented Loop Ports (SL_Ports) allow you to divide a Fibre 

Channel Private Loop into multiple segments. Each segment of the loop 
can pass frames around as an independent loop and can also connect 
through the fabric to other segments of the same loop. Refer to 

.

Each Translated Loop Port (TL_Port) connects to a private loop 

and allows connectivity between the private loop devices on the loop 
and “off-loop” devices (devices not connected to that particular 
TL_Port) such as Public fabric devices and private devices on other 
TL_Port loops. Refer to 

Trunk Ports (T_Ports) allow the interconnection of multiple chassis 

to form larger fabrics. Refer to 

.

•

All ports support Class 2 and Class 3 Fibre Channel service. Refer to 

 for more information.

•

The Switch supports the maximum Fibre Channel frame size (2148 bytes) for 
Class 2 and 3 Fibre Channel service. Refer to 

 for more information.

•

All ports are supported by GigaBit Interface Converters (GBICs). GBICs 
contain the transmitters and receivers that connect to the interconnection 
media. Each GBIC is “hot pluggable”.

•

Each port has eight buffer credits. This feature allows a cable length up to 13 
km at 1 Gbps without performance degradation. F_Port and T_Port credits 
can be extended by chaining ports together. Refer to 

 for more information about extending port credits. Cable length is 

also dependant on the type of GBIC used. Refer to 

 for more information.
