Upgrading to the PRP Step 5 Use the copy tftp: disk1: command to copy onto the Flash disk a PRP image that is the same as that currently running on the GRPs (in this example, 12.0(26)S). PRP images are titled c12kprp--.120-. You will receive an error that the PRP image is not executable on the GRP. When prompted to abort the copy, type n. Use the copy tftp: stby-disk1: command if the Flash disk is in the standby RP.
Upgrading to the PRP Note • Upgrading the RP ROM Monitor Using Cisco IOS Release 12.0(24)S or Later, page 34 • Upgrading the RP ROM Monitor Prior to Cisco IOS Release 12.0(24)S, page 35 The PRP-2 does not require an RP ROM monitor upgrade before Cisco IOS Software Release 12.0(30)S.
Upgrading to the PRP Step 8 Upgrade the ROM monitor image in RP1 using the upgrade rom-monitor slot sec-rp-slot command. If the routine finds that an upgrade is necessary, the new code will begin to be loaded. Once complete, reload the standby RP using the hw-module standby reload command. Upgrading the RP ROM Monitor Prior to Cisco IOS Release 12.0(24)S If your RPs are running a software image prior to Cisco IOS Release 12.
Upgrading to the PRP Upgrading to the PRP With Rebooting the Router If for any reason you cannot use High Availability, you should use the following procedure to upgrade from a GRP to a PRP. Step 1 Remove the Flash disk from the PRP card and install it into slot 1 of the active GRP. The following message will be displayed; do not format the disk. 22:21:31: %PCMCIAFS-5-DIBERR: PCMCIA disk 1 is formatted from a different router or PC.
Upgrading to the PRP Step 13 Connect the Ethernet and console cables to the PRP. Step 14 Remove the Flash disk from slot1: on the GRP and insert the Flash disk into slot0: on the PRP. Step 15 Boot the router. Step 16 The router will come up with no configuration and prompt you to enter the Initial Configuration menu. Abort the Initial Configuration options by entering no when prompted.
Upgrading to the PRP Step 23 The router will now boot with the correct configuration as was previously running on the GRP. Perform any post-boot checks: verify that the line cards have booted, required interfaces are active, CEF is operational, IGP adjacencies have formed, and the BGP peerings are established. Differentiating Between PRP-1 and PRP-2 You can use the software to determine whether you have installed a PRP-1 or a PRP-2.
Upgrading to the PRP • Turboboot Approach • Pre-Staging Approach Turboboot Approach You can upgrade PRP-1 or PRP-2 with Cisco IOS XR software installed to PRP-3 using route processor failover (RPFO). RPFO helps to minimize downtime and ensures service availability. To support RPFO the PRP-1 or PRP-2 must have Cisco IO S XR Software Release 3.8.0 or a later release, which supports PRP-3.
Upgrading to the PRP Pre-Staging Approach In a pre-staging approach the PRP-3 is loaded with the necessary Cisco IOS XR Software Release 3.8.0 software image, optional PIEs, and SMUs in a standalone chassis. After PRP-3 is in working condition, insert into PRP-2 chassis. To upgrade PRP-1 or PRP-2 with Cisco IOS XR software to PRP-3, perform the following steps: Step 1 Turboboot PRP-3 in a standalone chassis. Step 2 Install the necessary PIEs, SMUs on the PRP-3.
Configuring Interfaces on the PRP Step 5 Insert the PRP-3 into the Cisco XR 12000 Series Router chassis. Step 6 Turboboot the PRP-3 as indicated in section Turboboot Approach, page 39. Step 7 After PRP-3 finishes loading Cisco IOS XR Software image, load the converted Cisco IOS XR Software configuration. Step 8 Verify that all configurations are properly configured on PRP-3 and if the traffic has resumed.
Configuring Interfaces on the PRP Ethernet Interface Receptacles, Cables, and Pinouts There are two RJ-45 Ethernet interface receptacles on the PRP and one RJ-45 Gigabit Ethernet interface receptacle on the PRP-2, providing media-dependent interface (MDI) Ethernet ports. These connections support IEEE 802.3 and IEEE 802.3u interfaces compliant with 10BASE-T and 100BASE-TX standards. The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable.

Configuring Interfaces on the PRP-3 Configuring the Auxiliary Interface The auxiliary port on the PRP is a DTE, RJ-45 plug for connecting a modem or other DCE device (such as a CSU/DSU or another router) to the router. The port is labeled Aux, as shown in Figure 15. The asynchronous auxiliary port supports hardware flow control and modem control. Table 14 lists the pinout for this port.
Configuring Interfaces on the PRP-3 DETAILED STEPS Step 1 Step 2 Command or Action Purpose Identify the active RP or DRP. Identifies the RP or DRP to which you must connect in the next step. Connect a terminal to the Console port of the active RP or DRP. • This step is not required when the router hosts only one RP. • On a Cisco CRS-1 router, the active RP or DRP is identified by a lighted Primary LED on the RP front panel.
Configuring Interfaces on the PRP-3 Establishing a Connection Through a Terminal Server A terminal server connection provides a way to access the Console port from a remote location. It is less expensive to connect to the router through the Management Ethernet interface (because you do not have the additional cost of a terminal server). However, if you need to perform tasks that require Console port access from a remote location, a terminal server is the best connection method.
Configuring Interfaces on the PRP-3 DETAILED STEPS Step 1 Step 2 Command or Action Purpose Install and configure the terminal server. Prepares the terminal server for communications with the router and with Telnet clients. Connect the terminal server to the Console port of the target RP or DRP. • This step is usually preformed once. • For router access, users need the Telnet server IP address and port number for each RP they access.
Configuring Interfaces on the PRP-3 Step 6 Command or Action Purpose Press Enter. (Optional) Initiates communications with the RP or DRP. • If no text or router prompt appears when you start the Telnet session, press Enter to initiate communications. • If the router has no configuration, the router displays the prompt: Enter root-system username: Enter the root-system username and password when prompted.
Configuring Interfaces on the PRP-3 When you log in, the username and password may be validated by any of the following services: • Usernames configured on the router (username command in global configuration mode) • Root-system usernames configured on the owner SDR • Passwords configured for the router console and auxiliary ports (password or secret command in line configuration mode) • A RADIUS server • A TACACS+ server The username and password validation method that your router uses is determ
