You can easily customize the factory-default configuration with just a few commands.
Initially, you’ll need to make changes through the console port. After you configure the
management port, you can access the ACX7348 using SSH and make additional configuration
changes. You can revert to the factory-default configuration whenever you want.
Have the following information ready before you begin customizing the router:
Hostname
Root authentication password
Management port IP address
Default gateway IP address
IP address and prefix length of remote prefixes
(Optional) SNMP read community, location, and contact information
To connect and configure the router from the console:
Verify that the following default serial port settings are configured on your laptop or
desktop PC:
Baud Rate—9600
Flow Control—None
Data—8
Parity—None
Stop Bits—1
DCD State—Disregard
Connect the console port on the ACX7348 to a laptop or a desktop PC using the RJ-45
cable and RJ-45 to DB-9 adapter. The console (CON) port is the
RJ-45 port on the Routing Engine.
Note:
We no longer include the RJ-45 console cable with the DB-9 adapter as part of the
device package. If the console cable and adapter are not included in your device
package, or if you need a different type of adapter, you can order the following
separately:
RJ-45 to DB-9 adapter (JNP-CBL-RJ45-DB9)
RJ-45 to DB-9 adapter (JNP-CBL-RJ45-DB9)
RJ-45 to USB-C adapter (JNP-CBL-RJ45-USBC)
If you want to use RJ-45 to USB-A or RJ-45 to USB-C adapter you must have X64
(64-Bit) Virtual COM port (VCP) driver installed on your PC. See, https://ftdichip.com/drivers/vcp-drivers/ to download the driver.
Note:
If your laptop or desktop PC doesn't have a serial port, use a serial-to-USB adapter
(not provided).
At the Junos OS Evolved login prompt, type root to log in.
You don't need to enter a password. If the software boots before you connect your
laptop or desktop PC to the console port, you might need to press the Enter key for the
prompt to appear.

root@re0# delete system commit factory-settings
Note:
ZTP is enabled on the ACX7348 in the factory-default configuration. You must stop ZTP
before you configure any settings. Until you assign a root password and perform an
initial commit, you might see ZTP-related messages on the console. You can safely
ignore these messages while you configure the root password.
Add a password for the root administration user account.

Note:
By default, users are not allowed to log in to the router as root users through
SSH.
