At the end of the boot process, the LEDs are controlled by the Cisco IOS software
(via the MBus), and the content displayed is designated by the Cisco IOS
software.

•
• System error messages
User-defined status and error messages
•
A complete, descriptive list of all system and error messages is located in the
Cisco IOS System Error Messages publications.
The soft reset switch causes a nonmaskable interrupt (NMI) and places the PRP
in ROM monitor mode. When the PRP enters ROM monitor mode, its behavior
depends on the setting of the PRP software configuration register. (For more
information on the software configuration register, see the

boot field of the software configuration register is set to 0x0 and you press the
NMI switch, the PRP remains at the ROM monitor prompt (
a user command to boot the system manually. If the boot field is set to 0x1, the
system automatically boots the first IOS image found in the onboard Flash
memory SIMM on the PRP.
The soft reset (NMI) switch is not a mechanism for resetting the PRP and
reloading the IOS image. It is intended for software development use. To prevent
system problems or loss of data, use the soft reset switch only on the advice of
Cisco service personnel.
Access to the soft reset switch is through a small opening in the PRP faceplate. To
press the switch, you must insert a paper clip or similar small pointed object into
the opening.
