Power over Ethernet - NET-POE-PSW-404 8-Port 100/10Mbps Ethernet Switch with 4 x PoE Ports

Read our PoE white paper - Discusses PoE technology, what it's used for. How it works. Also discusses some of our PoE products

The PheeNet PSW-404 is an 8-Port 10/100Mbps Fast Ethernet Switch with 4-Port PoE. The PoE ports meet the standard of IEEE802.3af with maximum of 15.4W per port. For those users who have PoE built-in devices and are look for a cost-effective solution, the PSW-404 is an ideal choice.

1. 8 10/100Mbps Auto-negotiation Fast Ethernet RJ45 ports with 4-port PoE function.

2. Compliant with IEEE802.3af specification, Alternative A wireing (Power delivery over the data pins).

3. Supports PoE power maximum 15.4W for each PoE ports.

4. Supports PoE Powered Device (PD) classification identify.

5. Each port supports auto MDI/MDIX, so there is no need to use cross-over cables or an up-link port

6. Full/half duplex transfer mode for each port

7. Wire speed reception and transmission

8. Store-and-Forward switching scheme capability to support rate adaptation and ensure data integrity

9. Up to 1K unicast addresses entities per device, self-learning, and table aging

10. 96KBytes packet buffer

11. Supports IEEE 802.3x flow control for full-duplex mode ports

12. Supports Back-pressure flow control for half-duplex mode ports
