nComputer hardware limitations for l/O cards, if any.

The HP-UX and MPE XL operating systemssupport the useof this card. However, the particular computer model into which this card is installed may require special configuration rules due to power supply or slot limitations. This may affect the number or combination of interface cards authorized for use. To prevent card or systemdamage,be sure to consult your systeminstallation and configuration manuals for authorized I/O card cageconfigurations.

nSystemperformance implications, if any.

All HP-PB I/O cards are guaranteed to be able to acquire the HP-PB backplane for communication with the central processingunit (CPU) or memory. However, the I/O card in the highest numbered slot mayacquire the bus more frequently.

(That is, if all cards arbitrate for the bus continuously, the card in the highest slot will acquire it about 50% of the time.)

The SCSI/parallel adapter is a high-performance card. In general, if your applications require high performance through this card and you are not concerned about the performance of other I/O cardsin your system,then select the highest numbered slot. Otherwise, any other allowed slot would be suitable. You should check your systeminstallation or configuration manuals for any recommended configurations.

Record the Slot Number

The HP-PB slot number is used to calculate the card’s hardware addressduring system configuration. The slot number is labled on the computer and may be an even or odd digit. Hexadecimal notation maybe used. If the slot number will be difficult to obtain oncethe computer is reassembled,record the number now.
