Chapter 5 Preparing RPM-PR Cards for Operation
Initializing RPM-PR Cards
When the RPM-PR card starts or reboots, it searches for the configuration file in the following sequence:
• If there is a configuration file only on the PXM45 hard disk, the RPM-PR card uses the configuration
stored on the hard disk.
• If there is no configuration file on the hard disk, then the NVRAM version is used.
• If configuration files exist on both the hard drive and bootflash, the switch examines a timestamp
tag in each file. If the timestamp tag is the same in both files, the RPM-PR card uses the
configuration file stored in bootflash. If the timestamp tag is different, the RPM-PR card uses the
configuration file stored on the hard drive.
To initialize an RPM-PR card, use the following procedure.
Step 1 Establish a configuration session with the switch using a user name at any access level.
Note Access to the RPM-PR configuration is secured by the Cisco IOS software running on the card.
Step 2 To display the files that can be used to start RPM-PR cards, enter the cd command to select the E:RPM
directory, and enter the ll command to display the directory contents. For example,
pop20two.7.PXM.a > cd E:RPM
pop20two.7.PXM.a > ll
size date time name

In the file system :
total space : 102400 K bytes
free space : 92334 K bytes
The file that contains the word boot is for booting the card when the regular runtime image,
rpm-js-mz_122-4.T in this example, cannot load. The boot file is stored in bootflash on the card, and
loaded from that location. The switch never loads the boot code from the PXM45 hard disk. However, it
is common practice to store the boot code on the hard disk in preparation for a bootflash upgrade.
Write down the filename for the runtime image. You will have to enter this filename later in this
procedure.
Note If the runtime file is missing, you can transfer the correct file to the switch. This procedure is
described in Appendix A, “Downloading and Installing Software Upgrades.”
Step 3 Use the cc command to select the card slot in which the RPM-PR card is installed. For example,
pop20two.7.PXM.a > cc 9
(session redirected)

As shown in the example, the switch displays the prompt for the Cisco IOS software on the RPM-PR
card.
