lNIC cannot communicate with net
Action
1. Enter the System Setup program and confirm that the NIC is enabled.
See "Using the System Setup Program" in the User's Guide for instructions.
2. Check the two indicators on the left and right corners of the NIC connector on the system's back-panel (see Figure5-4).
The green link indicator shows that the adapter is connected to a valid link partner. The amber activity indicator lights if network data is being sent or received.
lIf the link indicator is not on, check all cable connections.
lTry changing the auto-negotiation setting, if possible.
lTry another port on the switch or hub.
3. If the activity indicator does not light, the network driver files might be damaged or deleted.
4. Reinstall the drivers.
5. Make sure the appropriate drivers are installed and the protocols are bound.

Figure 5-5. 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 system board can accommodate up to seven PCI expansion cards (two cards at 64-bit/66 MHz, three cards at 64-bit/33
MHz, and two cards at 32-bit/33 MHz). The peripheral bay provides space for a 3.5-inch diskette drive and a CD-ROM drive and two other devices (hard-disk
drives, tape drives).
The hard-disk drive bays provide space for up to six 1-inch SCSI hard-disk drives. These hard-disk drives are connected to a SCSI host adapter on the system board
or on an expansion card, via the SCSI backplane board.
Power is supplied to the system board, SCSI backplane board, and internal peripherals via a single non-redundant power supply. There is an option for up to three
