Appendix B: Upgrades and Troubleshooting

Upgrades
Below are the six files added to the standard Linux files in the /mnt/flash directory when an
upgrade is needed.
• boot_alt - alternate boot code
• boot_conf - active boot code
• boot_ori - original boot code
• config.tgz - ACS console server configuration information
• zImage - Linux kernel image
To upgrade the ACS console server:
1. Log in to the ACS console server as root.
2. Go to /mnt/flash.
3. FTP to the host where the new firmware is located.
4. Log in to the FTP server and go to the directory where the firmware is located.
# ftp
ftp> open server
ftp> user admin
ftp> Password: adminpw
ftp> cd /tftpboot
ftp> bin
ftp> get zImage.134 zImage
ftp> quit
NOTE: The destination filename in the /mnt/flash directory must be zImage. Example (hostname = server;
directory = /tftpboot; username= admin; password = adminpw; firmware filename on that server = zImage.134).
NOTE: Due to space limitations, the new zImage file may not be downloaded with a different name, then
renamed. The ACS console server searches for a file named zImage when booting and there is no room in Flash
for two zImage files.
5. To make sure the downloaded file is not corrupted and to verify the zImage saved in Flash run
the following command.
md5sum /mnt/flash/zImage
The system responds with a message similar to the following.
5bcc7d9b3c61502b5c9269cbecd20317
6. Check the system's response against the .md5 zImage text file on the tftp server.
/mnt/flash/zImage
