Product Overview

PRP Reset Switch

Caution

OL-17440-01

Access to the (soft) reset switch is through a small opening in the PRP front panel

(see

Figure

1-11). To press the switch, insert a paper clip or similar small pointed

object into the opening.

The reset switch is not a mechanism for resetting the PRP and reloading the

Cisco IOS image. It is intended for software development use only. To prevent

system problems or loss of data, use the reset switch only on the advice of Cisco

service personnel.

Pressing the 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

example, if the boot field of the software configuration register is set to:

0x0—The PRP remains at the ROM monitor prompt (rommon>) and waits for

•

a user command to boot the system manually.

0x1—The system automatically boots the first Cisco IOS image found in

•

flash memory on the PRP.
