USB Port Specifications for the QFX Series
The following Juniper Networks USB flash drives have been tested and are officially supported for the
USB port in the QFX Series:
•
RE-USB-1G-S—1-gigabyte (GB) USB flash drive (except QFX3100 Director device)
•
RE-USB-2G-S—2-GB USB flash drive (except QFX3100 Director device)
•
RE-USB-4G-S—4-GB USB flash drive
CAUTION: Any USB memory product not listed as supported for the QFX Series 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.
CAUTION: Remove the USB flash drive before upgrading Junos OS or rebooting a QFX
Series device. Failure to do so could expose your device to unpredictable behavior.
NOTE: Executing the request system snapshot CLI command on a QFX3500 device requires an
external USB flash drive with at least 4 GB of free space. We recommend using the RE-USB-4G-S
flash drive.
NOTE: USB flash drives used with the QFX Series device must support USB 2.0 or later.
