The NXA-ENET24 PoE Fast Ethernet switch is specifically designed to protect the
video streams coming from AMX’s MAX units to the Audio Video Modules (AVM).
Standard switches will reduce bandwidth from all applications when there is heavy
data traffic passing through the switch. For streaming audio and video applications this
will cause skipping and jitter in the audio and video feeds. This is unacceptable for
AMX’s applications. As a result, AMX has designed the NXA-ENET24 PoE to protect
the A/V streams when heavy data traffic occurs. Bandwidth is reduced from other
applications such as file transfer, e-mail and web surfing only when heavy data traffic
events occur.
The NXA-ENET24 PoE also provides a full range of features for Layer 2 switching. It
includes a management agent that allows you to configure the features listed in the
products manual. The default configuration can be used for most of the features
provided by this switch. However, there are many options that you could configure to
maximize the switch’s performance for your particular network environment.
The NXA-ENET24 PoE’s 24 10/100 Mbps ports support the IEEE 802.3af Power-over-
Ethernet (PoE) that enables DC power to be supplied to attached devices over the
unused pairs of wires in the connecting Ethernet cable.

10/100BASE-T Ports
The switch base unit contains 24 10BASE-T/100BASE-TX RJ-45 ports. All ports
support automatic MDI/MDI-X operation, so you can use straight-through cables for all
network connections to PCs or servers, or to other switches or hubs.
Each of these ports support auto-negotiation, so the optimum transmission mode (half
or full duplex), and data rate (10 or 100 Mbps) can be selected automatically. If a
