Data transmission ranges
Table 10 provides the data transmission ranges for different cable types and port
speeds.

Fibre Channel port specifications
The Fibre Channel ports in the SAN16B-2 are compatible with SWL and LWL SFPs.
The strength of the signal is determined by the type of SFP in use.
The ports are capable of operating at 1, 2, or 4 Gb/sec, and are able to autosense
to the highest speed capable for all attached devices.
Serial port specifications
The serial port is located on the port side of the switch. It is a three-wire RS–232
port with a DB–9 male connector, designed to connect to a DTE port.
Note: To provide dust and ESD protection, keep the safety plug on the serial port
whenever the port is not in use.
You can use the serial port to connect to a computer workstation to configure the
switch IP address without connecting to the fabric. The serial port's parameters are
9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control.
