QIC Tape Drive -Narrow SCSI 2.5GB, 5GB & 8GB             

Models Covered:

TDC 4220 (2.5GB)

TDC 4222 (5GB) Compressed

SLR 5  (8GB) Compressed

Installation Notes

Mounting drive top- or bottom-flush against a flat surface will impede air flow and cause overheating of the capstan motor. Allow at least 10mm (.40") clearance. Recommended mounting position is either horizontal with the indicator to the left, or vertical with the indicator down. Drive must NOT be mounted with the cartridge operating upside down.

The mounting screws provided are 3mm in diameter and 10mm in length. A serrated washer is also provided. To ensure proper securing of the drive only 3mm diameter screws should be used and the thread engagement into the drive chassis must be a minimum of 5mm (.20")  and a maximum of 7.5mm (.30"). Do NOT bend or twist aluminum chassis when tightening the mounting screws.

For internal tape installation, the computer power supply must be able to provide sufficient amperage for all installed equipment including the tape drive. When adding up power requirements of devices, be sure to use start-up values for motorized devices such as disk drives and the tape drive.

Remove the Resistor Packs (RP) when the drive is NOT mounted at the end of the SCSI bus or when external bus termination is used on  the same cable.

Use only certified quality tape cartridges. Do NOT use worn or audibly noisy cartridges. Cartridges which repeatedly require rewriting should be rejected. Cartridges should be exposed to the actual operating environment for at least 4 hours. Each time a cartridge is inserted in the drive, the tape should be run one complete end-to-end pass (retension), prior to start of the write operation.

Head cleaning with the Cleaning Cartridge Kit is recommended after  every 8 hours of tape running or after every 7 days of power-on.  Always clean head immediately after using a new cartridge, after a  large number of rewrite or reread operations, and after a hard read or  write error. Do NOT use any hard or sharp objects that might scratch  the surface of the head. Even small scratches may damage the head permanently.

The drive supports self diagnostics: automatically at power-up and at reset or manually by user activation. Selftest is invoked by using the straps located at rear of drive.

ATTENTION

Your drive installation kit contains parts that allow it to be used with a variety of Acer Altos systems. Not all parts will be used on all systems. For details about installing drives, refer first to your system's User's Guide.
