Configuration Rules for HP 9000 Model 800 Ex5 Class Systems
There are no power supply constraints for supported I/0 cards and peripherals.
You can not install more than two 3.5-inch SCSI-2 disks and two removable media devices.
You can install up to four single-high I/0 cards or two double-high cards in the systems,
depending on the number of I/0 slots.
Note
•
Please consult the most current configuration guides for additional
configurations of new HP-PB cards .
Configuration Rules for HP 3000 Series 9x8 Systems
The Series 9x8 systems require power budgeting, because they cannot support all
combinations of IO cards and internal peripherals.
In general, if PBA-IB Interface cards and HP-FL cards are not installed in the system, all
other combinations of cards, memory, and peripherals are supported.
Configuration Guidelines
1. Memory modules can use either two or four memory SIMM slots. However, enter the
current requirements in only one of the slot positions. Refer to Table 4-2 for the current
requirements of the memory modules.
2. When double-high I/0 cards are installed, two single-high slots are used. However, enter
the current requirements in only one of the slot positions. Refer to Table 4-2 for the
current requirements of the I/0 cards.
3. Refer to Table 4-2 for the current requirements of the internal peripherals.
4. The current requirements for the CPU card and the multifunction I/0 card have already
been taken into account in the worksheet calculations.
Calculating Current Consumption
Use the current tables and worksheet as follows, referring to Table 4-3.
1. Enter the current (amps) for each row corresponding to the selected memory SIMMs, I/0
cards, and internal peripherals. Be sure to enter the current values for all three voltages.
2. Sum each column and compare the results with the current limits at the bottom of
the worksheet. The Total Current Available already contains a 5% margin over the
total current available. If the configuration exceeds the available current shown, the
configuration must be modified to be supported.
