A-Class System Service
A-Class Server Trouble Shooting
Reset button while toggling the server’s power switch to OFF then ON. Do not
release the Web Console Reset button until selftest completes (the only front
panel LED lit is the green POWER LED).
NOTE
Resetting the Web console to its default configuration will require the Web console
to be reconfigured. Refer to Chapter 2 for the procedure.
6. Connect an ASCII console to the RS232 port on the rear of the server and
remove the LAN cable from the LAN Web console port on the rear of the server.
Refer to Chapter 2 for ASCII Console operation tips. If the ASCII console
works, but the Web console does not, the problem is with the system board. To
change the system board, you must replace the A-Class Exchange Base Unit
(EBU). Refer to the “Replacing an A-Class Server Exchange Base Unit (EBU)”
section.
7. If neither the ASCII nor the Web consoles work, the system board is the problem
in this case, also. Refer to the “Replacing an A-Class Server Exchange Base
Unit (EBU)” section.
NOTE
If you can access the console but do not get a prompt, it may be that you do not have
write access to the console. Multiple users may have access to the console (read
access) at the same time, but only one user can write to the console at a time. To see
which user has write access to the console, look at the Web console main screen.
The user whose name is underlined has write access to the console. Write access can
only be taken, not given. To acquire write access, press ctrl F12. Your username will
now be underlined and you will be able to enter commands into the Web console
system. Everyone else is excluded from writing to the console, but everyone on the
system has read access.
Troubleshooting Embedded Disks
The A-Class server will support a maximum of two internally installed and
connected disk drives, commonly referred to as embedded disks. Embedded disks
contain both the server’s startup (bootstrap) software and Operating System
software. Though embedded disks are installed internally, the server’s front panel
LEDs do not reflect disk status and therefore will not blink in a code pattern to
indicate an embedded disk selftest failure. Also, embedded disks do not have an
individual fault LED to show operational status.
