The upgraded range of SRX firewalls is equiped with both a DB9 port serial console and a Silicon Labs console with a mini USB port.

If a DB9-USB adapter is not availabale, grab the silicon labs drivers from following Juniper KB https://kb.juniper.net/InfoCenter/index?page=content&id=KB31671&actp=RSS

Once the driver has been installed, connect the usb-miniUSB into the SRX300 front mini usb and run screen to connect to the USB console:
Code:
$ ls -la /dev/*USB*
crw-rw-rw-  1 root  wheel   20,   7 Mar 20 14:58 /dev/cu.SLAB_USBtoUART
crw-rw-rw-  1 root  wheel   20,   6 Mar 20 04:33 /dev/tty.SLAB_USBtoUART
$ screen /dev/cu.SLAB_USBtoUART 9600
