Are you referring to the dongle on the ethernet-3 card? That's the only card that requires a dongle because of its stupid design. Other TNT cards do not require any dongle because they have the correct pinout. If you are using a MAX dongle, then I'm 100% sure you don't need it: you probably have a mismatch that gets masked by the dongle. Dongle or no dongle, the thing to remember is that the 100 MB ports on the 4/1-ether-card and 4-ether2-card cards do not autonegotiate half/full duplex. This is due to how the signalling works during autonegotiation and due to the particular PHY chips used in those cards. The 10/100 option may be negotiated correctly but the half/full duplex part will not be negotiated. When using these cards, switches that attempt to autonegotiate half/full duplex will fail and usually drop to half-duplex because it is safest. If you have a 4/1-ether-card or a 4ether2-card and experience intermittent traffic disruptions on your 100MB link, check first that both sides agree on all settings (10/100, half/full). If the switch can only autonegotiate (ie, it can't be configured to a fix setting), then set your TNT for _half_ duplex. -J ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request at bungi.com To get FAQ'd: <http://www.nealis.net/ascend/faq>
