MAINTENANCE AND SERVICING M2488 USER’S GUIDE
6-4 CG00000-011403 REV. A April 1997
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 the M2488 PRODUCT GUIDE, 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 maintenance provider.
Host jobs in progress that are using the tape unit should be aborted. Write data should be considered
not valid. Read data on the media is not effected.
6-5 CARTRIDGE RECOVERY WITH AN ACL
A CHK C8, CHK C9, CHK D8, or a CHK DA error may occur when using the ACL. These errors may
occur due to one of the following:
• The cartridge was not fully inserted into the drive.
• The cartridge was partially ejected into or out of the magazine.
• The mount arm did not return to home position, possibly due to the magazine obstructing the return
path.
Press RESET to eject the cartridge. If this does not work, continue with the Test Mode procedure to
recover the cartridge.
6-5.1 Test Mode Procedure
This procedure is used to recover a cartridge that has not loaded or ejected properly. This procedure
will only function if the tape system’s power supply, logic and electromechanical processes are
intact.
Confine hands to the Operator Panel to prevent inju-
ries from moving parts.
The Test Mode, unlike the normal operating mode,
keeps driving the motor selected by the operator
while the pushbutton is depressed. If the electrome-
chanical assembly binds, immediately release the
pushbutton.
