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
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 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.
