Flash Memory

You can use the flash memory on the RSP card to store multiple Cisco IOS XR software and microcode
images that you can use to operate the router. You can download new images to flash memory over the
network (or from a local server) to replace an existing image or to add it as an additional image. The
router can be booted (manually or automatically) from any of the stored images in flash memory.
Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to allow other servers to
boot remotely from the stored images, or to copy them into their own flash memory.
The system uses two types of flash memory:
•Onboard flash memory (bootflash)—Contains the Cisco IOS XR boot image
•Compact flash memory disks (or cards)—Contains the Cisco IOS XR software images
Note The RSP-440, RSP-440 Lite, RSP-880, and RP cards do not have a compact flash slot.
Table 4 -5 lists supported compact flash disk sizes and Cisco part numbers.
Troubleshooting RSP and RP Cards
When the router is powered on, the alphanumeric display on the RSP indicates the following sequence:
INIT—Card is inserted and microcontroller is initialized.
BOOT—Board is powered on and CPU is booting.
IMEM—Start initializing memory.
IGEN—Start initializing the board.
ICBC—Start initializing communication with the microcontroller.
PDxy—Loading programmable devices (x = FPGA, y = ROMMON).
PSTx—Power on self test x.
RMN��All tests are finished and ROMMON is ready for commands.
LOAD—Downloading Minimum Boot Image (MBI) image to CPU.
MBI—Starting execution of MBI.
IOXR—Cisco IOS-XR software is starting execution.
ACTV—RSP role is determined to be active RSP.
STBY—RSP role is determined to be standby RSP.
PREP—Preparing disk boot.
