The library should be placed in an area with minimal sources of particulate
contamination. Avoid areas near frequently used doors and walkways, stacks of
supplies that collect dust, printers, and smoke-filled rooms.
Air quality
Excessive dust and debris can damage tapes and tape drives.
CAUTION: Chemical contaminant levels in customer environments for HP hardware
products must not exceed G1 (mild) levels of Group A chemicals at any time as
described in the current version of ISA–71.04–1985 Environmental Conditions for
Process Measurement and Control Systems: Airborne Contaminants.

TIP: Temperature and humidity specifications are more tightly controlled for tape media, tape
drives, and tape libraries than many other products installed in the data center. Ensure that the
tape media and drives reside in an area within the temperature and humidity specifications.
Planning the module and rack layout
When possible, install the base module near the middle of the rack at a convenient height for
viewing and operating the OCP and accessing the mailslot. If the library will be sharing the rack
with other equipment, place heavy devices, such as disk arrays, in the bottom of the rack to reduce
the chance of the rack tipping.
The library supports up to three expansion modules above and three modules below the base
module, for a total of seven modules. Each module occupies 6U.
For maximum library expansion, install the base module as the centered module of the rack,
allowing 18U above the top of the base module and 18U below the bottom of the base module.

Planning the Fibre Channel configuration
You can connect the library directly to the server with a host bus adapter (HBA) or indirectly through
a storage area network (SAN) with a switch.
