power inline

Syntax:

Use this command to turn

power inline [auto test]

power on for a specific port or

no power inline

• auto - The switch automatically detects if a device is connected to the port

force a port into test mode.

and turns power on or off accordingly.

Use the no form to turn off

• test - Forces the port into a test mode. In test mode the port continuously

power for a port.

attempts to detect if a device is connected to the port, but does not supply

 

 

power.

 

Default Setting: auto

 

Command Mode: Interface Configuration

 

Command Usage: Using the command without an argument enables port

 

power in auto mode (the same as the power inline auto command).

 

In the default auto mode, power is automatically supplied when a device is

 

detected on the port, providing that the power demanded does not exceed

 

switch’s power budget.

 

Example:

 

Console(config)#interface ethernet 1/1

 

Console(config-if)#power inline auto

 

Console(config-if)#exit

 

Console(config)#interface ethernet 1/2

 

Console(config-if)#no power inline

 

Console(config-if)#

 

 

power inline maximum

Syntax:

allocation

power inline maximum allocation [milliwatts]

Use this command to limit the

no power inline maximum allocation

• milliwatts - The maximum power budget for the port.

power allocated to specific

Range: 3000 - 15400 milliwatts.

ports.

Default Setting: 15400 milliwatts

Use the no form to restore the

default setting.

Command Mode: Interface Configuration

 

Command Usage: If a device is connected to a switch port and the switch

 

detects that it requires more than the maximum power allocated to the port,

 

no power is supplied to the device (the port power remains off).

 

Example:

 

Console(config)#interface ethernet 1/1

 

Console(config-if)#power inline maximum allocation 8000

 

Console(config-if)#

 

 

power inline priority

Syntax:

Use this command to set the

power inline priority priority

power priority for specific ports.

no power inline priority

• priority - The power priority for the port.

Use the no form to restore the

Options: 1 (critical), 2 (high), or 3 (low).

default setting.

 

Default Setting: 3 (low)

 

Command Mode: Interface Configuration

 

Command Usage: If the power demand from devices connected to the

 

switch exceeds the power budget setting, the switch uses port power priority

 

settings to control the supplied power. For example:

 

• A device connected to a low-priority port that causes the switch to exceed

 

its budget is not supplied power.

 

• A device connected to a critical or high-priority port that causes the switch to

 

exceed its budget is supplied power, but the switch drops power to one or

 

more lower-priority ports.

 

• Power is dropped from low-priority ports in sequence starting from port

 

number 1.

 

Example:

 

Console(config)#interface ethernet 1/1

 

Console(config-if)#power inline priority 2

 

Console(config-if)#

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.
