Power And Space Budgeting For The Hp-Pb Card Cage; Power Budgeting Worksheets - HP 3000 99x Family Installation Manual

I/O Card Slot Height
802.5 Token single-high
Ring
LAN/Console double-high
PSI single-high
1. A maximum of 5 connections for SCSI and a maximum of 5 connections for HP-FL
(PB-FL). Remaining slots can be used for other non-disk activity as long as power
limits are not violated. This limit applies to single disks as well as disk arrays.
2. First 802.3 LANIC standard in LAN/Console card.
Boot disk - system performance may be enhanced by separating system software and user data on
separate disk arrays.
NOTE HP recommends against putting printers on the same HP-IB card with a
system disk. This configuration has been reported to cause some data
corruption on the system disk.

Power and Space Budgeting for the HP-PB Card Cage

Because of power and space constraints, there are limits on the number and type of HP-PB
cards supported by an HP-PB cardcage. These limits apply both to an internal HP-PB
cardcage in the SPU cabinet, and to an external HP-PB cardcage in an expansion cabinet.
The HP-PB cards in an HP-PB cardcage must:
Not require more than 14 single-high slots. (One double-high card = two single high
cards.)
Not exceed the power available at each voltage:
71.64W at +12V.
161.58W at +5V.
23.64W at −12V.
Not exceed the total power available (222.82W).
