Link Speed & Duplex
In the default mode, the adapter will attempt to auto-negotiate with its link partner
to determine the best setting. If the adapter cannot establish link with the link partner
using auto-negotiation, you may need to manually configure the adapter and link
partner to identical settings to establish link and pass packets. This should only be
needed when attempting to link with an older switch that does not support auto-
negotiation or one that has been forced to a specific speed or duplex mode. Your link
partner must match the setting you choose.
CAUTION:
Only experienced network administrators should force speed and duplex
manually. The settings at the switch must always match the adapter settings. Adapter
performance may suffer or your adapter may not operate if you configure the adapter
differently from your switch.
Manually setting Speed &Duplex
By default, auto-negotiation is enabled. Change this setting only to match your
link partner.
1. Open the Device Manager and expand the Network Adapters section.
2. Right-click the Intel i350 Gigabit Network Connection you wish to configure and
select Properties.
3. Click the
Link Speed
tab.
4. Select the appropriate speed and duplex from the Speed and Duplex pull
down menu.
5. Click
OK
.
Gigabit Network Device Considerations
Per the IEEE specification, gigabit speed is available only in full duplex.
The settings available when auto-negotiation is disabled are:
•
10 Mbps or 100 Mbps Full duplex
(requires a full duplex capable link partner set to
full duplex). The adapter can send and receive packets at the same time. You must
set this mode manually.
•
10 Mbps or 100 Mbps Half duplex
(requires a link partner set to half duplex). The
adapter performs one operation at a time; it either sends or receives. You must set
this mode manually.
