Additionally, the ports autonegotiate at 1, 2, or 4 Gb/s and meet all required safety
standards. For more information about these standards, see Regulatory compliance

4/32B SAN Switch FC port specifications
The FC ports are compatible with SWL, LWL, and ELWL SFP transceivers. The strength of
the signal is determined by the type of transceiver in use.
The ports meet all required safety standards. For more information about these
standards, see Regulatory compliance notices .

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. For the 4/32B or 4/64 SAN
Switch it is an RJ45 connector. The serial port is used for initial IP address configuration
and for recovery of the switch to its factory default settings should Flash memory
contents be lost. The serial port connection is not intended for performance of normal
administration/maintenance functions. Customer or field personnel accessible functions
are limited to connecting a terminal to the port to re-initialize the switch defaults, which
will restore the switch to its factory configuration. This will be required to restore the
switch passwords to a known state and to allow users to set a specific switch IP address.
NOTE:
To protect the serial port from dust and electrostatic discharge (ESD), keep the cover
in place on the serial port when the port is not in use.
The serial port can connect to a workstation to configure the switch IP address without
connecting to the fabric. The serial port’s parameters are fixed at 9,600 baud, 8 data
bits, and no parity, with flow control set to None.
The port requires a straight serial cable with a female 9-pin subminiature-D connector.
Only pins 2, 3, and 5 are supported.
Table 30 describes the cabling pinouts.
