Networking

Network Security

Careful planning should be made before placing an Intonato 24 on a network that is accessible by the

public—for example, direct access to the device using an unsecured/weakly secured wireless network

or a network jack in a public area.

It is highly recommended that the Intonato 24 be placed on a protected, isolated network that

does not have any connection to the public. This prevents unauthorized users from reconﬁguring

or controlling the device. Most routers have built-in functions which help protect the network from

unauthorized users, such as MAC address ﬁltering, encryption, and disabling the SSID broadcast.

Check the documentation for the network router for information on conﬁguring available security

options.

Network Troubleshooting

The Intonato 24 must be connected to a DHCP-enabled network for initial conﬁguration and control.

Connecting the Intonato 24 to the network should be as easy as plugging it into the switch/router and

waiting for it to get assigned an IP address. However, some additional conﬁguration will be required

if using static IP addressing and/or network security features. If a network connection cannot be

established with the Intonato 24, try following these steps to resolve the issue:

1. Ensure Networked Devices are Powered On

Ensure the control device, all network peripherals (switches, routers, bridges, etc.), and the

Intonato 24 are powered on and wait a few minutes to allow all devices to boot and get assigned

IP addresses. Look at the Intonato 24’s back-panel LCD and ensure it has an IP address. If it

reads “0.0.0.0”, or a network connection still cannot be established, go to the next step.

2. Check Network Activity LEDs, Cables, and Connections

Ensure the yellow and green LEDs are lighting on the Intonato 24’s Ethernet

port. Also, ensure the port activity/link LEDs are lighting on the router (and

switch, if applicable). If using a wired connection from a computer, ensure

the Ethernet port LEDs light on the computer’s Ethernet port. Note that the

yellow LED may only ﬂash occasionally; this is normal.

If any of these activity/link LEDs are not lighting, try disconnecting then

reconnecting the corresponding Ethernet cable. If the LEDs still don’t light,

try swapping out the connected Ethernet cable for another, known-working

cable. Also, make sure the correct type of Ethernet cable is used. If using a crossover cable, it

may be causing the problem (depending on the capabilities of the router/switch) and the cable

may need to be replaced with a straight-through Ethernet cable.

If an Ethernet port’s LEDs begin lighting after reconnecting or swapping out cables, wait a few

minutes, check the Intonato 24’s back-panel LCD for an assigned IP address, then try

reconnecting with the JBL Intonato control app. If a network connection still cannot be

established, go to the next step.
