Mini-USB Port Pinout Specicaons
If your management host (laptop or PC) does not have a DB-9 plug connector pin or an RJ-45 connector
pin but has a USB port, you can connect your management host to the Mini-USB Type-B console port
by using a cable that has a standard Type-A USB connector on one end and a Mini-USB Type-B (5-pin)
connector on the other end.
The Mini-USB Type-B console port uses a Mini-USB Type-B connector to connect to a console
management device. The default baud rate for the console port is 9600 baud.
Table 61 on page 153 provides the pinout informaon of the Mini-USB Type-B console port.
