Table 3. Troubleshooting symptoms and actions (continued)
Device Suggested action
Serial port problems Verify that:
1. Each port is assigned a unique address by the Configuration/Setup Utility
program and none of the serial ports are disabled.
Note: The management C connector is the same as a serial port connector,
but it is used only by the integrated Netfinity Advanced System Management
Processor, and is not available for use by the operating system. This port does
not appear in the Configuration/Setup Utility program menus; it can be
configured using Netfinity Manager.
2. The serial-port adapter, if you installed one, is seated properly.
If the problem still exists, call for service.
The number of serial ports
identified by the operating
system is less than the number
of serial ports installed.
Service processor problems Disconnect the appliance from all electrical sources, wait for 30 seconds, reconnect
the appliance to the electrical sources, and restart the appliance.
If a problem remains, call for service.
Netfinity Service Processor
Manager reports a general
monitor failure
Software problem To determine if problems are caused by the software, verify that:
1. Your appliance has the minimum memory requirements needed to use the
software. For memory requirements, refer to the information that comes with
the software.
Note: If you have just installed an adapter or memory, you might have a
memory address conflict.
2. The software is designed to operate on your appliance.
3. Other software works on your appliance.
4. The software that you are using works on another system.
If you received any error messages when using the software program, refer to the
information that comes with the software for a description of the messages and
solutions to the problem.
If the items above are correct and the problem remains, contact your place of
purchase.
Suspected software problem.
Troubleshooting the Ethernet controller
This section provides troubleshooting information for problems that might occur with
the 10/100 Mbps Ethernet controller.
Network connection problems
If the Ethernet controller cannot connect to the network, check the following:
v
Make sure that the cable is installed correctly.
The network cable must be securely attached at all connections. If the cable is
attached but the problem persists, try a different cable.
If you set the Ethernet controller to operate at 100 Mbps, you must use Category
5 cabling.
If you directly connect two workstations (without a hub), or if you are not using a
hub with X ports, use a crossover cable.
Note: To determine whether a hub has an X port, check the port label. If the
label contains an X, the hub has an X port.
v
Determine if the hub supports auto-negotiation. If not, try configuring the
integrated Ethernet controller manually to match the speed and duplex mode of
the hub.
v
Check the Ethernet controller lights on the operator information panel.
These lights indicate whether a problem exists with the connector, cable, or hub.
