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

In Figure 5-5, the system covers are removed and the bezel is opened to provide an interior view of the system.
Figure 5-5. Inside the System
The I/O board can accommodate up to 11 PCI expansion cards (10 PCI or PCI-X cards at 64-bit/33–100 MHz and one PCI card at 32-bit/33 MHz). The system
memory is contained on two separate riser cards that must be populated with at least two memory modules each for the system to operate. The peripheral
bay provides space for four additional 1-inch SCSI hard drives or one tape drive.
The hard-drive bays provide space for up to eight 1-inch SCSI hard drives. These hard drives are connected to a RAID controller card through the SCSI
backplane board.
The power distribution board (PDB) provides hot-plug logic and power distribution for the system. Your system can utilize an AC module or an optional,
integrated, redundant AC power module to provide AC current to the hot-pluggable power supplies. The AC module is used when a redundant AC power
source is not required. The integrated redundant AC power module enables your system to use two AC inputs. Your system can operate on either of these
inputs and automatically switches from a failing AC power source. The three hot-pluggable power supplies slide into connectors mounted on the PDB and
provide power to the system board, SCSI backplane board, and internal peripherals.
For non-SCSI drives such as the diskette drive and CD drive, an interface cable connects the interposer board, attached to the CD/diskette drive tray, to the
peripheral riser card. For SCSI devices, interface cables connect externally accessible SCSI devices and the SCSI backplane board to a SCSI host adapter on
either the I/O riser card or an expansion card (for more information, see
During an installation or troubleshooting procedure, you may be required to change a jumper. For information on jumpers, see "Jumpers and

Responding to a Systems Management Alert Message

The optional systems management applications monitor 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 your systems management
software documentation.
