BLACK BOX→ Power Over Ethernet Switch(PoE) Installation and User Guide
Switching, Address Learning
The LP004A Series units have address table capacity of 2K node addresses, and are suitable for use in large networks. They are self-learning, so that as nodes are added or removed or moved from one segment to another, the LP004A- Series switch automatically keeps up with node locations.
An address-aging algorithm causes least-used addresses to fall out in favor of new frequently-used addresses. To reset the address buffer, cycle power down-and-up.
4.2 Auto-cross (MDIX), Auto-negotiation and Speed-sensing
The RJ-45 ports of LP004A POE Switch independently support auto-cross (MDI or MDIX) in auto-negotiation mode and will work properly with all the other connected devices with RJ-45 port whether it supports Auto-negotiation or not (e.g 10Mb Hub, media converter) or fixed mode at 10Mb or 100Mb Half/Full Duplex(managed switch). No cross-over cable is required while using the 6K8’s copper port to other devices. Operation is according to the IEEE 802.3u standard.
