Initial Configuration

Required Connections

The switch provides an RS-232 serial port that enables a connection to a PC or terminal for monitoring and configuring the switch. A null-modem console cable is provided with the switch.

When switches are stacked together, you must connect to the RS-232 port on the

Master unit to be able to access the CLI.

Attach a VT100-compatible terminal, or a PC running a terminal emulation program to the switch. You can use the console cable provided with this package, or use a null-modem cable that complies with the wiring assignments shown in the Hardware Configuration Guide.

To connect a terminal to the console port, complete the following steps:

1.Connect the console cable to the serial port on a terminal, or a PC running terminal emulation software, and tighten the captive retaining screws on the DB-9 connector.

2.Connect the other end of the cable’s to the RS-232 serial port on the switch.

3.Make sure the terminal emulation software is set as follows:

Select the appropriate serial port (COM port 1 or COM port 2).

Set the data rate to 9600 baud.

Set the data format to 8 data bits, 1 stop bit, and no parity.

Set flow control to none.

Set the emulation mode to VT100.

When using HyperTerminal, select Terminal keys, not Windows keys.

1.When using HyperTerminal with Microsoft® Windows® 2000, make sure that you have Windows 2000 Service Pack 2 or later installed. Windows 2000 Service Pack 2 fixes the problem of arrow keys not functioning in HyperTerminal’s VT100 emulation. See www.microsoft.com for information on Windows 2000 service packs.

2.Refer to Line Commands section on page 9 for a complete description of console configuration options.

3.Once you have set up the terminal correctly, the console login screen will be displayed.

For a description of how to use the CLI, see Using the Command Line Interface section on page 171. For a list of all the CLI commands and detailed information on using the CLI, refer to Command Groups section on page 164.

Remote Connections

Prior to accessing the switch’s onboard agent via a network connection, you must first configure it with a valid IP address, subnet mask, and default gateway using a console connection, DHCP or BOOTP protocol.

The IP address for this switch is assigned via DHCP by default. To manually configure this address or enable dynamic address assignment via DHCP or BOOTP, see the Setting an IP Address section on page 13.

This switch supports four concurrent Telnet sessions.

After configuring the switch’s IP parameters, you can access the onboard configuration program from anywhere within the attached network. The onboard configuration program can be accessed using Telnet from any computer attached to the network.

The switch can also be managed by any computer using a Web browser (Internet Explorer 5.0 or above, or Netscape Navigator 6.2 or above), or from a network computer using network management software.

NXA-ENET24 specifications

The AMX NXA-ENET24 is a versatile and powerful networked control interface designed to meet the growing demands of modern AV systems. This network switch offers an exceptional combination of reliability, performance, and scalability, making it an ideal choice for professional environments such as conference rooms, educational facilities, and control rooms.

One of the key features of the NXA-ENET24 is its 24-port configuration, allowing for extensive connectivity options. Each port supports 10/100/1000 Mbps speeds, ensuring that high bandwidth applications are handled with ease. Additionally, the switch incorporates advanced auto-negotiation technology, which automatically configures the optimal speed and duplex mode for connected devices. This ensures seamless connectivity and minimizes the risk of network disruptions.

The NXA-ENET24 is designed with advanced management capabilities, including support for VLANs, which helps to segment network traffic for enhanced security and performance. Network administrators can easily create virtual local area networks to optimize traffic flow and reduce congestion. This feature is particularly beneficial in environments where multiple AV systems operate concurrently.

Another significant characteristic of the NXA-ENET24 is its support for Power over Ethernet, or PoE. This feature enables the switch to deliver electrical power alongside data through the network cables. As a result, devices such as IP cameras, VoIP phones, and wireless access points can be powered directly from the switch, simplifying deployment and reducing the need for additional power sources.

Monitoring and management of the switch are made easier through a user-friendly interface. The NXA-ENET24 supports SNMP for network management, allowing users to monitor performance metrics, configure settings, and receive alerts in case of issues. This level of oversight is crucial for maintaining the stability of AV systems in mission-critical applications.

Durability is another hallmark of the NXA-ENET24 design. The switch features a robust chassis that is engineered to withstand the rigors of professional use. With cooling mechanisms in place and a fanless design, the NXA-ENET24 operates quietly and efficiently, making it suitable for environments where noise is a concern.

In conclusion, the AMX NXA-ENET24 is a powerful, reliable, and feature-rich network switch that effectively supports modern AV applications. With its extensive connectivity options, advanced management capabilities, PoE support, and durable design, it is an excellent choice for integrators and organizations looking to optimize their network infrastructure.
