Serial port specifications
A
The ports meet all required safety standards. For more information about these standards, see
“Regulatory compliance” on page 32.
The ports are capable of operating at 1, 2, 4, or 8 Gbps and are able to autonegotiate to the higher
speed.
Serial port specifications
The serial port is located on the port side of the switch. The Brocade VA-40FC uses an RJ-45
connector for the serial port.
NOTE
To protect the serial port from damage, keep the cover on the port when not in use.
The serial port can be used to connect to a workstation to configure the switch IP address before
connecting the switch to a fabric or IP network. The serial port’s parameters are fixed at 9600
baud, 8 data bits, and no parity, with flow control set to None.
This connector is for initial IP address configuration and for recovery of the switch to its factory
default settings if Flash memory contents are lost. The serial port is not intended for performance
of normal administration or maintenance functions. You should only use this port to connect a
terminal to the port to re-initialize the switch defaults, restoring the switch to its factory
configuration. This is required to restore switch passwords to a known state and allow you to assign
an IP address to the switch.
Table 10 lists the serial cable pinouts.
