QFX5700 Console and Management Cable Specifications and Pinouts
The following sections describe the console port, the USB port, and the management port connections and specifications for the QFX5700 switch.
Management Cable Specifications for QFX5700 Switches
This table lists the specifications for the cables that connect the console and management ports to management devices.
Ports | Cable Specifications | Receptacle | Additional Information |
RJ-45 Console port | CAT5e unshielded twisted pair (UTP) cable | RJ-45 | |
Management Ethernet port | Ethernet cable with an RJ-45 connector | RJ-45 |
RJ-45 to DB-9 Serial Port Adapter Pinout Information
The console port 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. This table provides the pinout information for the RJ-45 to DB-9 serial port adapter.
The RJ-45 console port is a multiplexed port for both console (pins 3&6) and TOD (Time of the day), Pin 2 - TOD TXD, and Pin 7- TOD RXD. A split cable is required to use both the functionalities.
RJ-45 Pin | Signal | DB-9 Pin | Signal |
3 | TxD | 2 | RxD |
6 | RxD | 3 | TxD |
Console Port Connector Pinouts for a QFX5700
The console port (labeled CON) on the Routing and Control Board (RCB) panel is an RS-232 serial interface that uses an RJ-45 connector to connect to a console management device. The baud rate for the console port must be set to 115200 baud.
Table 2 provides the pinout information for the RJ-45 console connector.
- 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 PC does not have a DB-9 connector pin (plug) and you want to connect your laptop or PC directly to a QFX5700 switch, use a combination of the RJ-45 cable and RJ-45 to DB-9 adapter (not provided) and a USB to DB-9 plug adapter. You must provide the USB to DB-9 plug adapter.
Pin | Signal | Input/Output |
|---|---|---|
2 | TxD | OUT |
6 | RxD | IN |
USB Port Specifications for the QFX5700
The following Juniper Networks USB flash drives have been tested and are officially supported for the USB port in the QFX5700 switches:
RE-USB-1G-S—1-gigabyte (GB) USB flash drive
RE-USB-2G-S—2-GB USB flash drive
RE-USB-4G-S—4-GB USB flash drive
Any USB memory product not listed as supported for the QFX5700 switches has not been tested by Juniper Networks. The use of any unsupported USB memory product could expose your device 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.
Remove the USB flash drive before upgrading Junos OS or rebooting QFX5700 switches. Failure to do so could expose your device to unpredictable behavior.
USB flash drives used with the QFX5700 switch must support USB 2.0 or later.
