Chapter 1 Cisco 7200 Series Port Adapter Installation Requirements
Installation Requirements Based on the NPE or NSE Installed
Installation Requirements Based on the NPE or NSE Installed
To ensure that your Cisco 7200 series port adapter configuration is within the router operating
limitations, determine your model of network processing engine or network services engine and observe
the following guidelines:
•
For NPE-G1 or NPE-G2, go to the
“NPE-G1 or NPE-G2 Bandwidth Calculation and Configuration
Instructions” section on page 1-8
.
•
NPE-G1 or NPE-G2 with a Port Adapter Jacket Card—Bandwidth Calculation and Configuration
Instructions, page 1-9
•
For NPE-400, NPE-300 and NSE-1, go to the
“NPE-400, NPE-300, and NSE-1 Bandwidth
Calculation and Configuration Instructions” section on page 1-9
.
•
For NPE-225, NPE-200, NPE-175, NPE-150, and NPE-100, go to the
“NPE-225, NPE-200,
NPE-175, NPE-150, and NPE-100 Bandwidth Calculation and Configuration Instructions” section
on page 1-11
.
NPE-G1 or NPE-G2 Bandwidth Calculation and Configuration Instructions
Step 1
For each port adapter in your system, check the footnotes in
Table 1-6
to see if any apply to your system.
Step 2
If you have any dual-wide port adapters in your system, carefully read the port adapter configuration
document to see what special conditions apply to these port adapters.
Step 3
Calculate the bandwidth points requirements. For each port adapter in your system, go to
Table 1-6
and
write down the bandwidth points requirements. Use the blank
Bandwidth Calculation Table, page 1-22
,
to record your requirements.
Note
Do not calculate bandwidth points for an I/O controller if it is installed in the Cisco 7200 VXR
router with an NPE-G1 or NPE-G2. With the NPE-G1 or NPE-G2, I/O controllers do not use
bandwidth or bandwidth points.
Step 4
Assign each port adapter in your system to a chassis slot.
•
Make sure that the total bandwidth points for slots 0, 1, 3, and 5 (left bus) are less than or equal to
600.
•
Make sure that the total bandwidth points for slots 2, 4, and 6 (right bus) are less than or equal to 600.
Step 5
Make sure that the bandwidth points are evenly distributed between the left (odd-numbered slots) and
right (even-numbered slots) buses. Include the I/O controller in your determination of balance for the
left odd-numbered slots. Fill the slots in the following order: 2, 1, 4, 3, 6, 5.
Step 6
Check your Cisco IOS release and port adapter SDRAM memory requirements as detailed in
Chapter 2,
“Memory Requirements.”
.
You are finished calculating your port adapter configuration.
