Table 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.
