                          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   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

                          Product Overview   Asynchronous Serial Ports  The PRP has two asynchronous serial ports, the console and auxiliary ports. These  allow you to connect external serial devices to monitor and manage the system.  Both ports use RJ-45 receptacles. The console port provides a data circuit-terminating equipment (DCE) interface  for connecting a console terminal. The auxiliary port provides a data terminal  equipment (DTE) interface and supports flow control. It is often used to connect  a modem, a ch

                          Preparing for Installation    Cisco equipment operates safely when it is used in accordance with its  specifications and product usage instructions.  If you plan to replace a PRP, back up your current configuration file to a  remote server or to Flash memory before you remove the PRP. This prevents  you from having to reenter all your current configuration information  manually. To back up the file, copy your configuration file to a Flash disk or  access a remote server.
