Connecting a QFX Series Device to a Management Console
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
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.
