PCI Card Placement Rules 299
PCI Card Placement Rules
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.
Since Frame Relay will be used on the #4745, the detailed values for the synchronous
under 64 Kbps and Frame Relay under 2048 Kbps need to be used to account for the
usage on the #4745. Synchronous under 64 Kbps has a memory requirement of 3 and a
performance requirement of 7. Frame Relay under 2048 Kbps has a memory requirement
of 11 and a performance requirement of 13. Since the memory requirement for the two
protocols is less than the memory requirement for the card under the hard rules (11+3 or
14 versus 15), the Hard Rules value is left in the table. The combined performance
requirement (7+13 or 20) is greater than the hard rules memory requirement (7) so those
values are entered in the table.
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.
Once the IOAs specified for the embedded IOP are installed, the Model 820 Card Enclosure
will appear as shown in the following figure.
