1 Server Description
The NEC ProServa™ PH133 series of high performance Pentium® 133 MHz servers incorporate a modular
scaleable architecture that integrates a 64-bit bus interface with a Peripheral Component Interconnect (PCI)
PeerBus and an Extended Industry Standard Architecture (EISA) bus. The architecture supports symmetrical
multiprocessing (SMP) and a variety of operating systems. The bus interface is capable of handling multiple
processors with multiple cache resources in a quad-processor format.
The ProServa PH server's system board provides two central processing unit (CPU) module slots, two Error
Checking and Correcting (ECC) memory module slots, four PCI slots, and six EISA bus master slots. Four
standard peripheral bays can house optional diskette drives, tape back-up, CD-ROM (standard on some
configurations), and other mass storage devices. Six hot-docking bays provide over 12 gigabytes (GB) of storage.
The docking bays allow hot-swapping of SCSI hard disk drives without shutting down the server.
All server configurations contain a 525-watt power supply, 3 1/2-inch diskette drive, ECC memory module, and
CPU module. Several configurations contain two CPU modules, one or two 2-GB hard drives, an Intel
EtherExpress™ PRO/100B Adapter board, CD-ROM reader, Intel LANDesk Server Monitor, and a redundant
array of independent disks (RAID) controller. Figure 1-1 shows a typical server configuration. Table 1-1 lists the
server configurations.
Monitoring and control of the ProServa PH servers is provided by an onboard Interrupt Control ASIC (INCA)
component and several software applications, including Intel's LANDesk™ Server Control and LANDesk
Management Suite.
As application requirements increase, you can upgrade your system with dual or quad Pentium processors,
additional memory, additional drives and add-in expansion boards, and other peripheral devices.

Interrupt Controller (APIC)
Fully PCI 2.1 compliant bus performance at 33 MHz with a
bandwidth of up to 133 MB/second. The two 32-bit segments
provide maximum system performance.
bandwidth of up to 33 MB/second.
Two CPU module expansion slots support up to two CPU modules,
each containing up to two Pentium processors. Dual/quad
processing enhances system performance and enables symmetric
multiprocessing (SMP) on supported operating systems. Onboard
L1 cache has 8K each for code and data.
APIC controls interrupt detection and notification, and is
used in conjunction with SMP. Use of APIC reduces the load
on the system bus, as the APIC uses a serial bus to transmit
and receive interrupts.
Interrupt and Control ASIC
(INCA)
Onboard Interrupt and Control ASIC (INCA) provides PCI
interrupt control. An integrated automatic APIC sensor is
capable of full dual-Pentium and quad-Pentium processor
symmetric multi-processing support. An INCA component
provides support for PCI arbitration, interrupt steering, and a
second I/O APIC. It also drives the front panel interface and
LCD display for security and server management functions. A
System Management Interrupt (SMI) component monitors
the keyboard, mouse, system board voltages and
temperatures, and server door opening.

Chassis
The server system’s electro-galvanized metal chassis minimizes EMI/RFI. The
chassis contains:
SCSI-2 Single Connector
Attachment (SCA)
Compatible Backplane
Provides a continuous fast/wide SCSI bus for access to all
hot-swap drive bays. Allows SCSI-1
(5 MB/sec), fast/narrow SCSI-2 (10 MB/sec), or fast/wide
SCSI-2 (20 MB/sec) data transfers to the hard drives.
Additional details are given in Appendix C, "Technical Reference."

between 110 Vac and 220 Vac
two variable-speed hot-swap fans for interior cooling, with speed
determined by interior air temperature and number of installed hard
drives

drive
four standard 5 1/4-inch bays for mounting half-height peripheral
devices (CD-ROM, diskette drive, tape drive)

Two captive thumbscrews secure the removable metal door behind the lower plastic
front door to the chassis. The cover provides proper air-flow and easy access to the
hot-docking bays for hot-swapping SCSI-2 SCA hard disk drives in and out of the
server. The removable side cover, attached to the chassis with four screws, provides
proper airflow and easy access to the system board. You can secure the cover to the
chassis and the hot-docking bay metal door to the chassis with padlocks (not
provided). Figure 1-2 shows the major system components.
