IMG 1010 - Downloading System Software

Procedure:

  • Once all services are running and the IMG 1010 software build is available and installed on GCEMS server, power on the unit by toggling the power switch on the rear Power Module to 1(ON).

  • The fans on the IMG 1010 will now spin at Full Speed while the IMG 1010 diagnostics are running. Watch the LCD screen on the front of the IMG 1010. The following is what will be displayed on the LCD display.  

ROM information
MAC: XX:XX:XX:XX:XX:XX id0101
ROM: X.XX.XX

FTP Server Information
MAC: XX:XX:XX:XX:XX:XX id0101
FTP: XX.XX.XX.XX

Load Status
MAC: XX:XX:XX:XX:XX:XX id0101
Load OK/Jumping to Load

The last screen that appears is node information.
Node Name: IMG1010
NodeID: 255

The fans will return to normal operating speed at this time

  • If the above steps do not happen and the IMG 1010 will not load software see the Troubleshooting section below.
     

Troubleshooting

If the software load does not transfer to the IMG, check the following:

  • Verify that the Linux firewall is disabled. Within Menu Bar go to System Settings --> Security Level

  • Verify that DHCP and VSFTP services are running. Within Menu Bar go to System Settings --> Server Setting --> Services

  • Verify that the etc/dhcpd.conf file is correct.

  • Verify that the switch .bin file is in the correct location. (/home/excelsw/ftpBuilds).

  • Verify that the link to the switch bin created in /home/excelsw/ftpBuilds is correct.
    Example:  img1010_id0101.bin -> img1010_ver1050xxx_id0101.bin

If the system software image gets corrupted during the download process, the IMG 1010 will not load the corrupt image. Instead, the IMG 1010 display one of the errors below and then execute a reset of the IMG 1010.

Procedure:

  • Load build onto IMG1010

  • Check if an error is displayed on the front panel LCD

Expected Results:

IMG 1010 provides information to user via LCD that the build is bad and can’t be loaded. It also indicates what section of the file contains the error. Possible error values are:

  • ERROR: Bad TEXT checksum

  • ERROR: Bad DATA checksum

  • ERROR: Bad EHDR checksum

  • ERROR: Bad PHDR checksum
