PCI Card Placement Rules
294 AS/400e System Handbook
Example 1: Model 270
In this example, the customer has requested a Model 270 with the following capabilities:
• SixdiskarmswithRAID-5DiskProtection
• Electronic Customer Support (ECS)
• Attachment to a 100 Mbps Ethernet at the fastest possible throughput
• Twinax Console #5540
To provide these capabilities, the following IOP and IOA features are required:
• Embedded IOP
• #2842 PCI IOP
• #9771 Base PCI Two-Line WAN with Modem IOA (ECS will be manually configured)
• #4746 PCI Twinax Workstation IOA (provides Twinax Console)
• #2763 PCI RAID Disk Unit Controller (provides RAID-5 Disk Protection)
• #4838 PCI 100/10Mbps Ethernet (provides attachment to 100Mbps Ethernet)
Once the IOPs and IOAs are identified, you can validate the configuration using the
procedure from page “Generating a Valid Configuration” on page 284, as shown below.
The Embedded MFIOP is examined first:
1. Identify the IOP being considered.
The Embedded MFIOP 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 Embedded MFIOP 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.
Because there is a soft rule specifying to place the #4838 on a separate IOP for optimum
performance, the #9771, #4746, and #2763 will be controlled by the Embedded MFIOP.
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
default value for the IOA. When determining the values to use, be sure to account for both
lines if you have selected the #4745 and #9771.
