Memory Diagnostic
CC-SG is implemented with the Me diagnostic program, which
can be invoked from the GRUB menu . When any memory problems
occur, you can perform the Me diagnostic test for
troubleshooting.
1: Perform the Me diagnostic program:
1. Reboot CC-SG. See
Reboot CC-SG with Diagnostic Console
(on
page 316).
2. When it shows the messages below, press any character within 5
seconds to enter the GRUB menu, such as the Esc or arrow key.
Press any key to enter the menu

3. Highlight the "Me vX.X" option (where vX.X is the current
version) using the up or down arrow keys, and press Enter.
4. CC-SG loads and performs the Me diagnostic program. Let
the program run at least one complete pass, that is, when the Pass
column shows "1". For extensive test, leave the program running for
multiple hours or even overnight.
5. Verify these items to determine whether there are memory errors.
Memory: The amount of total memory should match your CC-SG
type: 512M for G1, 2048M for V1, and 4096M for E1.
Errors: The column should show "0"
Error display area: The area is the bottom area right below the
WallTime row. The program should display nothing in this area to
indicate there are no errors.
If any of the above items indicates that there are memory errors, you
can:
