I am trying to install a Digital (Compaq?) DE500 network adapter into a Compaq Proliant 1500 server (approx. 4 years old). When I configure the NIC to autosense the speed, or force the speed to 10 Mbit (full duplex or half duplex), everything works fine.
Autosense sets the NIC to 10 Mbit, so I tried forcing the NIC to 100 Mbit. No go. The 100 Mbit LED on the NIC goes on, but the link LED goes off. The NIC is connected to a 10/100 Mbit autosensing switch. I tried patching the connection to a switch port that surely works at 100 Mbit, and it gives the same results.
This problem is reproducible on:
- NT Server 3.51, SP 5, with the drivers that shipped with the NIC
- NT Server 4.0, SP 6, with the NT drivers that shipped with NT
- NT Server 4.0, SP 6, with the drivers that shipped with the NIC
I have used the NIC in other machines, and it worked flawlessly. My uneducated guess is that the Proliant server is refusing to co-operate with the adapter. Any help will be greatly appreciated.
