Cisco Systems NPE-225 사용자 설명서

If your router is mounted in a 4-post or telco-type rack, make sure you have at least one other person 
available to assist you with removing the chassis from the rack.

The network processing engine and network services engine have different requirements for both 
hardware and software. See the 

. 

Cisco IOS Release 12.2 changed the behavior of the ROM monitor (ROMmon) during the bootup 
sequence. See 

 for more information.

When installing an NPE-175, NPE-225, NPE-300, NPE-400, NPE-G2, or NSE-1 in a Cisco 7200 VXR 
router or Cisco uBR7246VXR router that is using a previously purchased I/O controller, you must 
upgrade the I/O controller boot helper image. The Cisco uBR7225VXR router does not support port 
adapters or I/O controllers.

Instructions for upgrading the boot helper image on the I/O controller are contained in the online 
Memory Replacement Instructions for the Network Processing Engine or Network Services Engine and 
Input/Output Controller publication.
