patterns are disrupted within the system. To maintain correct airflow patterns within the
chassis and to ensure that all components remain within specification under all system
environmental conditions, fan hot-swap operations should not exceed two minutes in
duration.
The E-Bay contains the baseboard with the following components:
• Up to four Intel Pentium III Xeon processors. The baseboard has four SC330.1
connectors; each supports a processor. There are also four embedded voltage
regulator modules (VRM) and three VRM 8.3-compliant connectors to support up
to four processors.
• The Server Set III HE chipset. This includes the HE North Bridge, Open South
Bridge (OSB4), and I/O.
• Up to sixteen PC/100-compliant registered ECC SDRAM memory modules that
support up to 16 gigabytes of Error Checking and Correcting (ECC) Synchronous
Dynamic RAM.
• 32-bit, 33-MHz, 5 V PCI segment with two expansion slots and three embedded
devices.
• 64-bit, 66/33-MHz, 3.3 V hot-Plug PCI segment with two expansion slots and one
embedded device.
• 64-bit, 33-MHz, 5 V hot-Plug PCI segment with four expansion slots and three
embedded devices.
• Compatibility bus segment with three embedded devices.
• Two externally accessible USB ports.
• One Adaptec AIC-7880 SCSI controller.
• One Adaptec AIC-7899 SCSI controller.
The Adaptec AIC-7899 SCSI controller has two channels called A and B. Channel A is
connected to the HDD backplane. Channel B is connected to the back of the system to
which external SCSI devices may be connected.
The Adaptec AIC-7880 SCSI controller supports both a legacy wide SCSI device and
legacy narrow SCSI device.
