Chapter 2. Planning
The library requires an environment able to accommodate the appropriate space, power, location, and
other technical specications. Use this section as a reference for onsite requirements to allow for
optimum operation of the library.
Save your settings in the Appendix D, “Library Conguration Forms,” on page 189.
Operating environmental specications
Refer to these environmental specications to determine where to place your tape system
Table 18 on page 29 lists the recommended environmental specications for the tape library when
operating and when powered off. Figure 20 on page 30 is a psychrometric chart showing the allowable
and recommended operating environments. Table 18 on page 29 and Figure 20 on page 30 applies to
LTO drive generations 1 through 9, and all supported 3592 drives except TS1170.
Table 19 on page 30 and Figure 21 on page 31 applies to TS1170 only.
Attention: The environments in Table 18 on page 29 refer to the hardware
of the tape system and may lead to temperatures greater than allowable for
the cartridges and media stored therein. Refer to the following topics and
adjust the operating environment for the library accordingly.

Notes:
1. Product equipment is removed from the original shipping container and installed but not in use - for example, during repair, maintenance, or upgrade.
2. Derate maximum dry-bulb temperature 1°C/300 m above 900 m (1.8°F/1,000 feet above 3,000 feet).
3. Derate maximum recommended dry-bulb temperature 1°C/300 m above 1,800 m (1.8°F/1,000 feet above 6,000 feet).
4. For 3592 media, changes of up to 40% RH in 5 minutes are allowed as long as the 20% to 80% absolute limits are not exceeded.
5. Applies to LTO drive generations 1 through 8 and to legacy 3592 drives (TS1155 and prior generations).
6. Applies to TS1160 and LTO 9 drives.
