Action

1. Check the appropriate indicator on the NIC connector (see Figure2-6).

A green indicator shows that the adapter is connected to a valid link partner. A blinking amber indicator shows that network data is being sent or

received.

l If the link indicator is not on, check all cable connections.

l Try changing the auto-negotiation setting, if possible.

l Try another port on the switch or hub.

If you are using a NIC expansion card instead of the integrated NICs, see the documentation for the NIC card.

2. If the indicator does not light, the network driver files might be damaged or deleted. Check the drivers, and remove and reinstall the drivers if

applicable.

You must reboot your system for the reinstalled drivers to become active.

3. Ensure that the appropriate drivers are installed and the protocols are bound.

4. Enter the System Setup program and confirm that the NICs are enabled (see "Using the System Setup Program" in the User's Guide).

5. Ensure that the NICs, hubs, and switches on the network are all set to the same data transmission speed.

6. Ensure that all network cables are of the proper type and do not exceed the specified length. For more information, see "Network Cable Requirements"

in the User's Guide.

Inside the System

Figure 5-4. Inside the System



The system board holds the system's control circuitry and other electronic components. Several hardware options, such as the microprocessors and memory,

are installed directly on the system board. The expansion-card cage accommodates up to three full-length PCI or PCI-X expansion cards.

The system provides space for a 3.5-inch diskette drive and a CD drive. The CD/diskette drive tray connects to the controllers on the system board through the

SCSI backplane board. For more information, see "Installing Drives."

The hard-drive bays provide space for up to five 1-inch SCSI hard drives. The hard drives connect to a controller on the system board or a RAID controller card

through the SCSI backplane board. For more information, see "Installing Drives."

During an installation or troubleshooting procedure, you may be required to change a jumper setting. For more information, see "Jumpers and Connectors."

Responding to a Systems Management Alert Message

The optional systems management software monitors critical system voltages and temperatures, the system cooling fans, and the status of the SCSI hard

drives in the system. Alert messages appear in the alert log window. For information about the alert log window and options, see the systems management

software documentation.
