Page 13: Introduction
All the 10BASE-T/100BASE-TX ports on this switch support IEEE 802.3af standard Power-over- Ethernet capabilities. Each port can detect connected 802.3af-compliant network devices, such as AMX’s NXA-WAP 200 G, other third party’s wireless access points or IP phones, and automatically supply the required DC power. -

Page 15: Description Of Hardware
Introduction Description of Hardware Physical Description The NXA-ENET24 and the NXA-ENET24 PoE Fast Ethernet switches measure 17.32 x 16.14 x 1.69 inches (44.0 x 41.0 x 4.3 cm). 10/100BASE-T Ports The PoE 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. - Page 16 Port has detected a power overload or short circuit and shut down the port’s power. The power budget for the switch has been exceeded and the port's power shut down. No powered device is connected to the port.
