NPE-G2 Memory Information and Specifications
  •
SDRAM—synchronous dynamic random-access memory.
  •
SDRAM-fixed—SDRAM of a fixed size or quantity; can be replaced, but not upgraded.
  •
SFP module—small form-factor pluggable module.
  •
Unified cache—Instruction cache and data cache are combined. For example, a processor may have 
primary cache with separate instruction and data cache memory, but unified secondary cache.
  •
USB—universal serial bus.
NPE-G2 Memory Information and Specifications
To determine the memory configuration of your NPE-G2, use the show version command.
The following example shows an NPE-G2 installed in a Cisco 7206VXR router.

PCI bus mb1 (Slots 1, 3 and 5) has a capacity of 600 bandwidth points.
 
Current configuration on bus mb1 has a total of 780 bandwidth points. 
 
The set of PA-2FE, PA-POS-2OC3, and I/O-2FE qualify for "half 
 
bandwidth points" consideration, when full bandwidth point counting 
 
results in oversubscription, under the condition that only one of the 
 
two ports is used. With this adjustment, current configuration on bus 
 
mb1 has a total of 480 bandwidth points. 
 
This configuration is within the PCI bus capacity and is supported 
 
under the above condition. 
PCI bus mb2 (Slots 2, 4 and 6) has a capacity of 600 bandwidth points.
 
Current configuration on bus mb2 has a total of 1000 bandwidth points.
 
The set of PA-2FE, PA-POS-2OC3, and I/O-2FE qualify for "half 
 
bandwidth points" consideration, when full bandwidth point counting 
 
results in oversubscription, under the condition that only one of the 
 
two ports is used. With this adjustment, current configuration on bus 
 
mb2 has a total of 800 bandwidth points. 
 
This configuration has oversubscripted the PCI bus and is not a 
 
supported configuration. 
Please refer to the following document "Cisco 7200 Series Port Adaptor
 
Hardware Configuration Guidelines" on Cisco.com <http://www.cisco.com>
 
for c7200 bandwidth points oversubscription and usage guidelines.
