Console Port Connector Pinout Information
The console port on a Juniper Networks device is an RS-232 serial interface that uses an RJ-45 connector to connect to a console management device. The default baud rate for the console port is 9600 baud.
Table 2 provides the pinout information for the RJ-45 console connector.
We no longer include the RJ-45 console cable with the DB-9 adapter as part of the device package. If the console cable and adapter are not included in your device package, or if you need a different type of adapter, you can order the following separately:
- RJ-45 to DB-9 adapter (JNP-CBL-RJ45-DB9)
- RJ-45 to USB-A adapter (JNP-CBL-RJ45-USBA)
- RJ-45 to USB-C adapter (JNP-CBL-RJ45-USBC)
If you want to use RJ-45 to USB-A or RJ-45 to USB-C adapter you must have X64 (64-Bit) Virtual COM port (VCP) driver installed on your PC. See, https://ftdichip.com/drivers/vcp-drivers/ to download the driver.
If your laptop or desktop PC does not have a DB-9 plug connector pin and you want to connect your laptop or desktop PC directly to a device, use a combination of the RJ-45-to-DB-9 socket adapter and a USB-to-DB-9 plug adapter. You must provide the USB-to-DB-9 plug adapter.

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 3 provides the pinout information of the Mini-USB Type-B console port.

USB Port Specifications for an EX Series Switch
Juniper Networks tested and officially supports the following USB flash drives for the USB port on all EX Series switches:
-
RE-USB-1G-S
-
RE-USB-2G-S
-
RE-USB-4G-S
Any USB memory product not listed as supported for EX Series switches has not been tested by Juniper Networks. The use of any unsupported USB memory product could expose your EX Series switch to unpredictable behavior. Juniper Networks Technical Assistance Center (JTAC) can provide only limited support for 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.

The Ethernet cables that you use to connect to the RJ-45 network ports on EX4300-48MP and EX4300-48MP-S switches and provide 95-W power over 4-pair wire must meet the following specifications related to deployment, temperature rise, category, IEEE, UL, NEC, and local electric codes to ensure proper performance and to not exceed rated temperature and ampacity of cables:
The cables must be shielded RJ-45 cables.
The cables must be rated for IEEE 802.3 BT, TIA standards, and UL-LP.
The cables must follow NEC 725.144 article and local electric code.
The operating temperature of the cable must be rated at 15° C more than the ambient temperature.

RJ-45 to DB-9 Serial Port Adapter Pinout Information
The console port on a Juniper Networks device is an RS-232 serial interface that uses an RJ-45 connector to connect to a management device such as a laptop or a desktop PC. If your laptop or desktop PC does not have a DB-9 plug connector pin and you want to connect your laptop or desktop PC to the device, use a combination of the RJ-45 to DB-9 socket adapter along with a USB to DB-9 plug adapter.
Table 10 provides the pinout information for the RJ-45 to DB-9 serial port adapter.
