LVD Product Information
Internal Components
Microprocessors
The J6000 has two PA-8600 microprocessors with operating frequencies of 552 MHz. Each
processor has 0.5 MB instruction cache and a 1.0 MB data cache. Each microprocessor is
cooled by a “turbocooler” which consists of a cylindrical heat sink and an integrated fan.
Power Supply
The power system is comprised of one apparent power factor 500W output power supply.
The maximum power needed by a fully-configured SPU is 715W input power. The
temperature sensor is located in the front of the power supply. The power supply weighs
approximately 8 lbs. (4 kg.). Please note that the system speaker is located in the power
supply.
CAUTION HP does not recommend and does not support the use of “ferro-active” or
“ferro-resonant” power correction in conjunction with the J6000 workstation.
This type of line conditioner represents an older technology that is not
compatible with the most recent designs in active Power Factor Correction
(PFC) power supplies such as those in the HP J6000 workstations.
“Ferro-active” or “ferro-resonant” line conditioners may cause an increase in
total harmonic distortion and may produce significant and unpredictable
voltage regulation anomalies.
PCI Cage
The PCI (Peripheral Connect Interface) cage is located on the left side of the system board,
behind the CD ROM and hard disk drive bays. There are three PCI-4X, 64 bit, 3.3v, 66
MHz slots which provide I/O expansion capabilities for the workstation. There are no
primary and secondary card slots.
CD ROM and Hard Disk Drive Bays
The J6000 supports two Low-Voltage Differential (LVD) SCSI hard disk drives (one
standard and one optional) and one optional ATAPI slim-line CD ROM drive. The internal
SCSI Bus is independent of the external SCSI Bus.
The hard disk drives are hot-pluggable. More information on this was provided earlier in
this chapter in the Hard Disk Drive section.
Voltage Regulator Modules (VRMs)
NOTE These VRMs are designed to function ONLY with the J6000 power supply.
The output is 2VDC. The maximum current is 52A.
