Table 7. NDIS (Windows NT or Windows 2000) driver teaming messages for the Ethernet controller. Event ID 12 13 14 15 16 17 18 19 20 21 Type Warning Informational Informational Error Informational Informational Informational Informational Informational Warning Description Explanation: Team nn. Secondary adapter is deactivated from the Team. Action: Make sure the secondary adapter is functioning properly and that the adapter cable is securely connected to the LAN. Explanation: Team nn. Secondary adapter has rejoined the Team. Action: None. Explanation: Team nn. Secondary adapter link is up. Action: None. Explanation: Team nn. The last adapter has lost its link. Network connection has been lost. Action: Shut down the server and replace the adapters; then, restart the server to reestablish the connection. Explanation: Team nn. An adapter has re-established the link. Network connection has been restored. Action: None. Explanation: Team nn. Preferred primary adapter has been detected. Action: None. Explanation: Team nn. Preferred secondary adapter has been detected. Action: None. Explanation: Team nn. Preferred primary adapter took over. Action: None. Explanation: Team nn. Preferred secondary adapter took over. Action: None. Explanation: Team nn. Primary adapter does not sense any Probes. Possible reason: partitioned Team. Action: Make sure the cables of the adapter team are connected to the same LAN segment. Reconfigure the team if necessary. Power checkout Power problems can be difficult to troubleshoot. For instance, a short circuit can exist anywhere on any of the power distribution busses. Usually a short circuit will cause the power subsystem to shut down because of an overcurrent condition. A general procedure for troubleshooting power problems is as follows: 1. Power off the system and disconnect the AC cord(s). Disconnect all external cables and remove server from the rack. Note: To determine if the power switch assembly needs to be replaced turn on microswitch 5 on switch block 1 (power-on override) and reconnect the AC cord. If the system powers on within 40 seconds then replace the switch assembly. 2. Check for loose cables in the power subsystem. Also check for short circuits, for instance if there is a loose screw causing a short circuit on a circuit board. 3. Remove adapters and disconnect the cables and power connectors to all internal and external devices until system is at minimum configuration required for power-on. Note: Minimum configuration requirements are: a. 1 Power supply b. System board c. 1 Microprocessor d. 1 Terminator card e. Memory module (with a minimum of 128 MB DIMM) 4. Reconnect the AC cord and power on the system. If the system powers up successfully, replace adapters and devices one at a time until the problem is 24 Hardware Maintenance Manual: xSeries 330
