Important Information PRP Redundancy When two PRPs are installed in a Cisco 12000 Series Router, one PRP is the active PRP and the other is a backup, or standby, PRP. If the active PRP fails or is removed from the system, the standby PRP detects the failure and initiates a switchover. During a switchover, the standby PRP assumes control of the router, connects with the network interfaces, and activates the local network management interface and system console. Note If your system inclu

Important Information Note Output from the show version command on a PRP-2 card running on software releases prior to 12.0(30)S may display some incorrect information. This is only a display issue and it occurs because the software does not recognize some of the hardware on the card. This does not affect the functionality of the PRP-2. For example, the following is incorrect output from the show version command on release 12.0(22)S: cisco 12406/PRP (MPC7450) processor (revision 0x00) wi

Product Overview Flash Memory Flash memory allows you to remotely load and store multiple Cisco IOS software and microcode images. You can download a new image over the network or from a local server and then add the new image to Flash memory or replace the existing files. You then can boot the routers either manually or automatically from any of the stored images. Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to allow other servers to boot remotely fro

Product Overview Soft Reset Switch A soft reset switch provides a reset to the processor software on the PRP. You access the soft reset switch through a small opening in the PRP faceplate. To depress the switch, insert a paper clip or a similar object into the opening. Caution The soft reset 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
