Head Cleaning Procedure; Firmware Updates - HP 3000 9x9KS Service Manual

Head Cleaning Procedure

1. Cleaning Cartridge Product Number = HP 92283K.
2. Insert the cleaning cartridge into the drive.
3. The drive automatically cleans the drive heads and ejects the cartridge after approximately 30
seconds.
4. If the cleaning cartridge ejects after only 14 seconds, the cartridge has reached the end of its useful
life. (About 25 cleaning cycles.)
5. If the cycle is successful, remove the cleaning cartridge and record the use count on the label
supplied with the cartridge.
Table 8-19 is a cleaning frequency guideline.

Firmware Updates

Firmware updates can be done in 2 ways:
1. Download new firmware files provided with the software or as patches. This method requires the
availability of a diagnostic or utility which allows for software controlled downloading of firmware.
2. Update the firmware by way of a firmware upgrade tape available as an orderable part. The part
numbers for these tapes change on each new version release. These changes will be made available
by way of service note notifications.
Firmware Upgrade Tape Procedure:
• Shut down the operating system.
There can be no activity on the SCSI bus and no interruption of power during this procedure.
Either event can cause the device to become unusable (DEAD DRIVE) and will require the
device to be replaced.
• Clean the drive with the cleaning cartridge.
• Insert the firmware update tape. The drive will now take over the activity and accomplish the update.
• WAIT UNTIL ALL ACTIVITY HAS FINISHED before removing the update tape from the drive.
This is approximately 2 to 3 minutes.
