Tape Cartridge Specifications and Capacities
The tape drive uses prewritten cartridges. An 8-mm Travan (740 feet) 4.0 GB
capacity tape is recommended.
Regulatory Compliance
The tape drive complies with the regulations listed in the following table.
Regulatory Compliance
Agency Regulation
CSA C22.2, No. 950-M89
TUV & IEC-RHEINLAND EN 60 950/IEC 950
UL 1950
Canadian Department of Communications Class B
VDE Class B
FCC Class B, Part 15
Use the tape drive only in equipment where the combination has been determined
to be suitable by an appropriate certification organization (for example,
Underwriters Laboratories Inc. of the Canadian Standards Association in North
America). Consider the following safety points:
v Install the drive in an enclosure that limits the user’s access to live parts, gives
adequate system stability, and provides the necessary grounding for the drive.
v Provide the correct voltages (+5 V dc and +12 V dc) based on the regulation
applied — Extra Low Voltage (SEC) for UL and CSA and Safety Extra Low
Voltage for BSI and VDE (if applicable).
