HP E1439A CPU card

The twisted pair ports featured on the AT-8000 Series Switch are described below. Type of Connector All twisted pair ports feature 8-pin RJ-45 connectors. For the port pinouts, refer to ”RJ-45 Twisted Pair Port Pinouts” on page 85.Auto-Negotiation is activated as the default on all twisted pair ports on the switch. To deactivate Auto-Negotiation and set the speeds manually, refer to the AT-S39 Management Software User’s Guide.

The twisted pair ports are 10/100Base-TX compliant

 and are capable of both 10 megabits per second (Mbps) and 100 Mbps speeds. You can set the port speed manually or, since the ports are IEEE 802.3u AutoNegotiation compliant, you can let the switch set each port’s speed automatically. With Auto-Negotiation, the switch automatically matches the highest possible common speed between each switch port and each end-node. For example, if an end-node is capable of only 10 Mbps, the switch sets the port connected to the end-node to 10 Mbps.
