Release Notes for the Broadband Access Center for Cable Device Provisioning Engine 590 Recovery CD-ROM
March 7, 2005
This release note describes how to use the recovery CD-ROM to re-image a DPE-590 device. It contains the complete instruction set you must follow to re-install the original software image supplied on the DPE-590. After completing the recovery CD-ROM procedure, you must reconfigure the DPE-590 with the same configuration setting used on the previous DPE.
Using the Recovery CD-ROM
The Broadband Access Center for Cable Device Provisioning Engine 590 Recovery CD-ROM contains one complete image of the software originally installed in your device provisioning engine (DPE).
If you need to re-image your DPE, complete this procedure:
Step 1 Locate a Solaris computer that can export directories by means of Network File Sharing (NFS). Once you have identified this computer, share the DPE-590 directory of the recovery CD-ROM. To do this:
a. Open the /etc/dfs/dfstab file.
b. Identify the path to the directory that you want to share. For example:/cdrom/bpr_release_dpe-590/DPE-590
Note In the examples provided in this procedure, release identifies the release number being used. For example, if you are operating with BACC 2.5, then you would enter 25 at this location.
c. Add this line to the /etc/dfs/dfstab file:share -F nfs /cdrom/bpr_release_dpe-590/DPE-590
d. Enter these commands to restart the NFS server:/etc/init.d/nfs.server stop/etc/init.d/nfs.server start
The recovery CD-ROM should now be accessible on the network.
Step 2 Verify that the DPE is properly connected to the network and then use a terminal emulator program to connect to the console port on the DPE. Regardless of which emulator you use, you must configure these emulator settings: 9600 baud, 8 bits, no parity, 1 stop bit, and use hardware flow control.
Step 3 Verify that the DPE-590 is properly connected to the network and turn the power on.
Step 4 Press i within 5 seconds of the System Now Booting or the Booting CE From Flash message appearing on the screen. After approximately one minute the bash boot prompt appears.
Step 5 Enter this command at the bash prompt:bash# mount -t proc /proc /proc
Note All subsequent commands are entered at the bash prompt (bash#).
Step 6 Identify the IP address and subnet mask you will assign to the DPE. For example purposes, assume these are 10.10.10.1 and 255.255.255.0, respectively.
Step 7 Enter this command:ifconfig eth0 10.10.10.1 netmask 255.255.255.0 up
Step 8 Determine whether a default gateway is needed to connect to the NFS server. Assume that the IP address of this gateway is 10.20.20.2 and enter this command:route add default gw 10.20.20.2 eth0
Step 9 Determine the IP address of the NFS server containing the DPE-590 recovery CD (assume this to be 10.20.30.4) and the shared directory name (assume this to be /cdrom/bpr_release_dpe-590/DPE-590).
Step 10 Enter this command:mount -o nolock 10.20.30.4:/cdrom/bpr_release_dpe-590/DPE-590 /mnt/source
Note These warning messages may appear when you run the mount command:
nfs warning: mount version newer than kernel
nfs_read_super: get root fattr failed
Step 11 Enter this command to install the recovery image onto the DPE-590:/mnt/source/installer-bin/install-system.sh
Note While this command is running, a considerable amount of information is displayed on screen. The command is complete when the bash prompt re-appears.
Step 12 Enter these commands to complete the imaging:/mnt/source/installer-bin/umount /mnt/floppy/opt/mnt/source/installer-bin/umount /mnt/floppy
Step 13 Power cycle the DPE-590 and reconfigure it with the previous DPE configuration settings. Refer to the Broadband Access center for Cable Installation Guide for additional information.

Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool automatically provides recommended solutions. If your issue is not resolved using the recommended resources, your service request will be assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
