Power Supply
The maximum AC and DC power needed by a fully-configured SPU is 360W input power.
The temperature sensor is located at the front of the system board. The AC power supply
weighs approximately 5.8 lbs. (2.6 kg.) and the DC power supply weighs approximately 4.2
lbs. (1.9 kg.).
CAUTION HP does not recommend and does not support the use of "ferro-active" or
"ferro-resonant" power correction in conjunction with the B2600 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 B2600 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 drive bay area. There are two 32-bit, 5.0v, 33MHz slots and two 64-bit, 5.0v,
33MHz slots, which provide I/O expansion capabilities for the workstation. The two 32-bit
slots support short PCI cards, and the two 64-bit slots support short and full-length PCI
cards.
If you are installing a video card in you workstation, it is recommended that you install it
in slot three of the PCI cage. Note that any optional audio card should be installed in slot
one of the PCI cage.
CD Drive Bay and Hard Disk Drive Bays
The B2600 supports two Low-Voltage Differential (LVD) SCSI hard disk drives (one
standard and one optional) and one optional ATAPI CD drive. If you should install an
optional SCSI card in one of the four PCI slots located in you PCI cage, the internal SCSI
bus will be independent of the external SCSI bus.
