Juniper EX4300 Series

USB Port Specicaons for an EX Series Switch
Juniper Networks tested and ocially supports the following USB ash 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 ash drives.
All USB ash drives used on EX Series switches must have the following features:
• USB 2.0 or later.
• Formaed with a FAT or MS-DOS le system.
• If the switch is running Junos OS Release 9.5 or earlier, the formang method must use a primary
boot record. Microso Windows formang, by default, does not use a primary boot record. See the
documentaon for your USB ash drive for informaon about how your USB ash drive is formaed.
