l NIC cannot communicate with network.
Action
1. Run the appropriate online diagnostic test. See " Using Server Administrator Diagnostics " in "Running System Diagnostics."
If the tests fail, continue to the next step.
2. Check the appropriate indicator on the NIC connector. See Table 2 -2 in "Indicators, Messages, and Codes."
l If the link indicator does not light, check all cable connections.
l If the activity indicator does not light, the network driver files might be damaged or missing.
Remove and reinstall the drivers if applicable. See the NIC's documentation.
l Change the autonegotiation setting, if possible.
l Use another connector on the switch or hub.
If you are using a NIC card instead of an integrated NIC, see the documentation for the NIC card.
3. Ensure that the appropriate drivers are installed and the protocols are bound. See the NIC's documentation.
4. Enter the System Setup program and confirm that the NICs are enabled. See "Using the System Setup Program" in your User's Guide.
5. Ensure that the NICs, hubs, and switches on the network are all set to the same data transmission speed. See the network equipment documentation.
6. Ensure that all network cables are of the proper type and do not exceed the maximum length. See "Network Cable Requirements" in your User's Guide.

Figure 5-1. Inside the System
The system board can accommodate one or two microprocessors. The PCI riser board assembly accommodates up to two PCI expansion cards. Up to four
memory modules may be installed on the system board.
The hard-drive bays provide space for up to three 1-inch SCSI hard drives. SCSI hard drives are connected to a SCSI controller on the system board through
the SCSI backplane board.
The peripheral bays provide space for an optional 3.5-inch diskette drive and a CD drive.
The power distribution board (PDB) provides hot-plug logic and power distribution for the system. Two hot-pluggable, redundant power supplies provide
power to the system board and internal peripherals.
During an installation or troubleshooting procedure, you may be required to change a jumper. For information about the system board jumpers, see " Jumpers
and Connectors ."
