MAINTENANCE AND SERVICING M2488 PRODUCT GUIDE
8-2 CG00000-011503 REV. A April 1997
When an Ozone message is observed, the check code and text message should be recorded as well as
the current operating conditions and all data forwarded to Product Support for problem resolution. If
possible a Read Buffer CDB specifying the entire 2MB data buffer as a data length and a buffer start
address of zero should be issued from the host computer. This data should be made available to your
maintenance provider.
A table of ozone codes is not provided in this document as they are of little use to the user of the
product and are generated for the use of firmware developers only.
8-2.2 NVRAM Initialization Required
This message is displayed after power on if the non-volatile RAM that contains configuration and
setting information is not initialized, i.e.; CRC error when reading the configuration file. It is possible
that the NVRAM was previously initialized but has since failed. When this message is displayed the
tape unit will not respond to SCSI selection until the configuration is performed via the operator
panel. See the User’s Guide, Chapter 4, SETTING MENU.
8-2.3 CHK XX
CHK xx errors signal drive or ACL/FACL errors when displayed on the operator panel. xx may be
any hexadecimal value from 00 to FF. When CHK XX is displayed, pressing the TEST key will cause
the operator panel to scroll a short descriptive text message describing the cause of the error. Pressing
the RESET key when a CHK XX message is displayed erases the message and unloads the tape car-
tridge and, when an autoloader is installed, ejects the magazine. A description of each check code is
contained in Appendix E.
The operator should press the reset key to eject the cartridge and magazine after recording the check
code and associated text. This information should be provided to the service engineer. Host jobs in
progress and using the tape unit should be aborted. Write data should be considered not valid. Read
data on the media is not effected.
8-2.4 Diagnostic Error Codes
The diagnostic error codes, as displayed on the operator panel or the maintenance terminal display,
are described in Appendix F.
8-2.4.1 Operator Panel Error Code Display
If an error occurs during power-on Go/No Go testing, an error message scrolls across the operator
panel display; i.e., SELFTEST FAILED ERROR=E:04070 101. Refer to Appendix F for a list
of error codes with descriptions.
