PCI Card Placement Rules 295
PCI Card Placement Rules
ECS will be the only protocol used on the #9771. None of the soft rules apply.
6. Add the IOA values in each column. Place the totals on line 5.
7. Compare the totals in line 5 with the IOP Capacity in line 6.
All the numbers in line 5 are less than or equal to the corresponding values in line 6.
Therefore, the configuration is valid.
Now that the validity of the embedded IOP and its associated IOAs has been determined, the
second IOP, a #2842, and its associated IOAs have to be checked:
1. Identify the IOP being considered.
The #2842 PCI IOP is to be used.
2. Determine the capacity values for the selected IOP using “IOP Capacity Table” on
page 285. Enter the values on line 6 of the Configuration Validation Form.
The #2842 PCI IOP has a memory capacity value of 100 and a performance capacity
value of 100. Those values are entered on line 6.
3. Identify the IOAs to be controlled by the selected IOP.
The #4838 PCI 100/10Mbps Ethernet will be controlled by the #2842.
4. Determine the capacity requirements of the selected IOAs using “Hard Rules: IOA
Capabilities” on page 286. Enter the values in the form on lines 1 through 4, one IOA per
line. Remember that an IOP supports a maximum of four IOAs.
The appropriate values were entered on lines 1 through 4. The slots that the cards will
occupy have also been entered.
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
