Memory Diagnostic<br />

CC-SG is implemented with the Memtest86+ diagnostic program, which<br />

can be invoked from the GRUB menu . When any memory problems occur,<br />

you can perform the Memtest86+ diagnostic test for troubleshooting.<br />

1: Perform the Memtest86+ diagnostic program:<br />

1. Reboot CC-SG (see "Reboot CC-SG with Diagnostic Console" on<br />

page 255).<br />

2. When it shows the messages below, press any character within 5<br />

seconds to enter the GRUB menu, such as the Esc or arrow key.<br />

Press any key to enter the menu<br />

Booting CentOS (x.x.x) in x seconds....<br />

3. Highlight the "Memtest86+ vX.X" option (where vX.X is the current<br />

version) using the up or down arrow keys, and press Enter.<br />

4. CC-SG loads and performs the Memtest86+ diagnostic program. Let<br />

the program run at least one complete pass, that is, when the Pass<br />

column shows "1". For extensive test, leave the program running for<br />

multiple hours or even overnight.<br />

5. Verify these items to determine whether there are memory errors.<br />

• Memory: The amount of total memory should match your CC-SG<br />

type: 512M for G1, 2048M for V1, and 4096M for E1.<br />

• Errors: The column should show "0"<br />

• Error display area: The area is the bottom area right below the<br />

WallTime row. The program should display nothing in this area to<br />

indicate there are no errors.<br />

If any of the above items indicates that there are memory errors, you<br />

can:<br />

• Capture the Memtest86+ screen containing the memory errors<br />

and contact <strong>Raritan</strong> Technical Support for assistance.<br />
