Software and Hardware Requirements

NPE-175, NPE-200, NPE-225 and the NPE-300 is a PLCC-type integrated circuit.

Software and Hardware Requirements
When installing a new NPE-100 or NPE-150 in a Cisco 7200 series router, you must replace the
existing boot ROM on the I/O controller with the updated boot ROM that shipped with the new
NPE-100 or NPE-150. Instructions for replacing a boot ROM on the I/O controller are contained in
the “Removing and Replacing Memory DRAM SIMMs, SDRAM DIMMs, and Boot ROMs”
section on page 20.
Note There is a boot ROM on the NPE-175, NPE-200, NPE-225 and on the NPE-300; therefore,
you do not have to replace the boot ROM on the I/O controller when installing a new NPE-175,
NPE-200, NPE-225, or NPE-300. When powering up a Cisco 7200 VXR router that has a newly
installed NPE-175, NPE-200, NPE-225, or NPE-300, or when powering up a Cisco 7200 router that
has a newly installed NPE-175, NPE-200, or NPE-225, the system automatically uses the boot
instructions contained in the NPE boot ROM and ignores the boot ROM on the I/O controller.
This note does not apply to the Cisco uBR7200 series or to the Cisco 7206VXR and Cisco 7206 as
router shelves in a Cisco AS5800 Universal Access Server.
