USB Port Specifications for an EX Series Switch
The following Juniper Networks USB flash drives have been tested and are officially
supported for the USB port on all EX Series switches:
■ RE-USB-1G-S
■ RE-USB-2G-S
■ RE-USB-4G-S
CAUTION: 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 Release 9.5 or earlier, the formatting method
must use a master boot record. Windows formatting, by default, does not use a
master boot record. See the documentation for your USB flash drive for
information on how your USB flash drive is formatted.
