PCI Card Placement Rules

To completely understand this procedure, review the examples provided in “Configuration
Validation Examples” on page 293.
Generating a Valid Configuration
To determine whether a specific IOP is capable of supporting the IOAs considered for
attachment, use the following procedures to complete the table in “Configuration Validation
Form” on page 285:
1. Identify the IOP being considered.
2. Determine the capacity values for the selected IOP using the “IOP Capacity Table” on
page 285. Enter the values on line 6 of the Configuration Validation Form.
3. Identify the IOAs to be controlled by the selected IOP.
4. Determine the capacity requirements of the selected IOAs using “Hard Rules: IOA
Capabilities” on page 286. Enter the values in the form in “Configuration Validation Form”
on page 285, on lines 1 through 4, one IOA per line. Remember that an IOP supports a
maximum of four IOAs.
5. Review “Soft Rules: IOA Requirements” on page 289. If any of the restrictions described
apply to the selected IOAs, use the values from the table to replace the values in the
Configuration Validation Form unless the value in a particular column is less than the
default value for the IOA. When determining the values to use, be sure to account for both
lines if you selected the #4745 and #9771.
6. Add the IOA values in each column. Place the totals on line 5.
7. Compare the totals in line 5 with the IOP Capability in line 6.
• If any number in line 5 is greater than the corresponding value in line 6, the selected
IOAs exceed the capacity of the selected IOP. Add one or more IOPs to the
configuration to support the selected IOAs.
• If all the numbers in line 5 are less than or equal to the corresponding values in line 6,
the configuration is valid as long as all card rules from “Hard Rules: IOA Capabilities”
on page 286, and “Soft Rules: IOA Requirements” on page 289, have been followed.
