CAUTION HP 10/100 Intel® EtherExpressTM PRO/100+Management Adapter Installation Guide Duplex Modes Duplex Modes This feature is provided on your HP 10/100 Intel EtherExpress PRO/100+ Management Adapter card, but is not supported by Hewlett-Packard: The PRO/100+ MA card provides a duplex mode.

Duplex Modes
Duplex Modes
This feature is provided on your HP 10/100 Intel EtherExpress
PRO/100+ Management Adapter card, but is not supported by
Hewlett-Packard:
The PRO/100+ MA card provides a duplex mode. Duplexing is a
performance option that enables you to choose how the adapter sends
and receives data packets over the Network. There are three possible
modes:
•
Auto mode.
1
The NIC negotiates with the hub to send and receive
packets at the highest rate. This is the default setting. If the hub does
not provide auto-negotiation, the adapter runs at half-duplex.
•
Full-duplex mode.
2
The adapter can send and receive packets at the
same time.
•
Half-duplex mode. The adapter performs one operation at a time.
The NIC can operate at full duplex only when connected to a full
duplex 10 BASE-T or 100 BASE-TX switching hub or to another full
duplex adapter.
CAUTION
Make sure the switch port and the adapter have the same duplex
setting. Setting the wrong duplex mode can reduce performance, cause
data loss, or result in lost connections.
1.
Requires a full-duplex adapter or a switching hub with auto negotiation capability.
2.
Requires a full-duplex switch or adapter. If the full-duplex switch provides
auto-negotiation, the adapter runs in full-duplex mode. If the full-duplex switch does
not provide auto-negotiation, you need to set the adapter duplex mode manually.
