Fujitsu manual Maintenance and Servicing M2488 Product Guide, Nvram Initialization Required

MAINTENANCE AND SERVICING M2488 PRODUCT GUIDE

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:04070101. Refer to Appendix F for a list
	of error codes with descriptions.
