CHAPTER 7 SPECIFICATIONS
Vibration Specifications
Tab le 7- 19 lists the operating specifications that indicate the amount of
vibration the tape drive can withstand while reading and writing data.
ENVIRONMENTAL CONDITIONS FOR THE VXATAPE CARTRIDGES
Tab le 7- 20 summarizes the environmental requirements for the VXAtape
cartridges. You should maintain the temperature and humidity at a steady
level within these ranges, and also limit fluctuations in temperature and
humidity.
Note: When a VXAtape is brought into the room where the VXA tape drive is
located, allow the VXAtape to adjust to room temperature and humidity
before using it.
