Chapter 8 Preparation for Installation
Software and Hardware Requirements
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.
Software and Hardware Requirements
The network processing engine and network services engine have different requirements for both
hardware and software. See the
“NPE or NSE Requirements” section on page 8-2.
Note Cisco IOS Release 12.2 changed the behavior of the ROM monitor (ROMmon) during the bootup
sequence. See “Boot Changes in Cisco IOS Release 12.2” section on page 10-2 for more information.
NPE or NSE Requirements
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.
Note 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.
