1 SYSTEM OVERVIEW
This manual describes the HP Vectra XM 5/xx series 4 PC , and provides detailed system
specifications. The PC is constructed around the Peripheral Component Interconnect (PCI) bus
and Industry Standard Architecture (ISA) bus. Its central feature is the Enhanced Ethernet
Network board fitted as standard in a new PCI slot on the backplane, and the ability to be
turned on remotely from another PC on the network.

INTERNAL FEATURES
Diagrams of the double-sided back-plane and the system board can be found at the beginning
of the next chapter. These show the locations of the PC’s main field-serviceable components.
The components of the system board are described in the same chapter. The characteristics of
the PC’s video, disk and networking devices are described in Chapter 3. The HP BIOS routines
are described in Chapter 4; the Remote Power-On (RPO) facility and Desktop Management
Interface (DMI) are described in Chapter 5; and the Power-On Self-Test routines are
summarized in Chapter 6.

When the PC is Off, but still
plugged in, an independent mini
power supply keeps the network
board active enough to watch out
for the “Remote Power-On” (RPO)
signal
An attempt to draw too much current (such as a short circuit across edge-connector pins, or an
accessory board that is not suitable for the PC), will cause the overload protection in the power
supply to be triggered, and the PC could fail to boot.

ENVIRONMENTAL SPECIFICATION
Environmental Specifications (System Processing Unit, with Hard Disk)
Operating Temperature + 40°F to 104° F (+5°C to +40°C)
Recommended Operating
Temperature +59°F to +158°F (+15°C to +30°C)
Storage Temperature -40°F to +158°F (-40°C to +70°C)
Over Temperature Shutdown +122°F (+50°C)
Operating Humidity 15% to 80% (relative)
Storage Humidity 8% to 80% (relative)
Acoustic noise emission <40 dB in the workplace under normal conditions
as defined by DIN 45635 T.19 and ISO 7779
Operating Altitude 10000 ft (3100m) max
Storage Altitude 15000ft (4600m) max
Operating temperature and humidity ranges may vary depending upon the mass storage
devices installed. High humidity levels can cause improper operation of disk drives. Low
humidity levels can aggravate static electricity problems and cause excessive wear of the disk
surface.
CONTROL PANEL
The control (status) panel of the HP Vectra XM 5/xx series 4 PC has the following features:
• a power on/off button with integrated on/error status light (which flickers in power-saving
mode)
• a
press-and-hold RESET button
• a hard disk activity light (for IDE drives)
• a keyboard lock button with integral status light
• a LAN activity light (for the network board).
