Mini-Usb Port Pinout Specifications - Juniper EX2300 Series Hardware Manual

issues related to unsupported hardware. We strongly recommend that you use only
supported USB flash drives.
All USB flash drives used on EX Series switches must have the following features:
• USB 2.0 or later.
• Formatted with a FAT or MS-DOS file system.
• If the switch is running Junos OS Release 9.5 or earlier, the formatting method must use a primary
boot record. Microsoft Windows formatting, by default, does not use a primary boot record. See the
documentation for your USB flash drive for information about how your USB flash drive is formatted.

Mini-USB Port Pinout Specifications

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 26 on page 86 provides the pinout information of the Mini-USB Type-B console port.
