IP700 Series Installation Guide
Operating Speeds of Network Interface Cards Used With the
IP700 Series Platforms
The following 66-Mhz and 33-Mhz cards are available from Nokia.
Configuration Guidelines for the IP740
To maximize the performance of your system, observe the following
guidelines.
Load Balancing Considerations
When you configure an IP740 appliance with only 66-Mhz cards
installed, keep both busses balanced by distributing the card-speed
requirements across both busses.
Balancing the busses is especially important if you are installing more
than one gigabit Ethernet card. For example, if you install the first gigabit
Ethernet card in slot 1, then your second card should go in slot 3, your
third in slot 2, and so on. However, if either of your busses is running at
33 Mhz, try to keep all gigabit Ethernet cards on the faster bus to attain
optimum performance from those cards.
