TCP/IP problems with an Ethernet network interface

If the network interface has been initialized, the addresses correctly specified, and you have verified that the adapter card is good:

• Verify that you are using a T-connector plugged directly into the inboard/outboard transceiver.
• Make sure you are using an Ethernet cable. (Ethernet cable is 50 OHM.)
• Make sure you are using Ethernet terminators. (Ethernet terminators are 50 OHM.)
• Ethernet adapters can be used with either the transceiver that is on the card or with an external transceiver. There is a jumper on the adapter to specify which you are using. Verify that your jumper is set correctly (see your adapter manual for instructions).
• Verify that you are using the correct Ethernet connector type (thin is BNC; thick is DIX). If you change this connector type, use the smit chgenet SMIT fast path to set the Apply Change to Database Only field. (Set to Yes in SMIT.) Restart the machine to apply the configuration change. (See Adapter management and configuration.)
