1.从Juniper官网下载相应的JUNOS(需要权限)
https://www.juniper.net/support/downloads/

2.将U盘格式化为FAT32的格式，并将JUNOS镜像文件拷贝到U盘
如:junos-srxsme-11.4R11.4-domestic.tgz

3.将U盘插入SRX100B的USB口，然后SRX100B会在console界面显示以下类似内容
umass1: detached
umass1: USB2.0 Flash Disk, rev 2.00/1.04, addr 4
da1 at umass-sim1 bus 1 target 0 lun 0
da1: <USB2.0 Flash Disk 8.07> Removable Direct Access SCSI-2 device
da1: 40.000MB/s transfers
da1: 3848MB (7880704 512 byte sectors: 255H 63S/T 490C)

4.在SRX100B上挂载U盘，da1是插入的U盘的标示
test@SRX100B>mount -t msdos /dev/da1s1 /var/tmp/usb

5.加载新版本的JUNOS
test@SRX100B>request system software add /var/tmp/usb/junos-srxsme-11.4R11.4-domestic.tgz

6.重启SRX100B
test@SRX100B>request system reboot

7.验证升级结果
test@SRX100B> show version
Hostname: SRX100B
Model: srx100b
