4 Preventive Maintenance
This chapter provides instructions for performing preventive maintenance on the XLS.
Preventive maintenance tasks include the following:
•
Checking the air filters (see Section 4.1 )
•
Replacing an air filter (see Section 4.2 on page 4-3 )
•
Inspecting the cartridge slots and fiducials (see Section 4.3 on page 4-5 )
•
Inspecting the fans (see Section 4.4 on page 4-7 )
•
Inspecting and cleaning the gripper pads and sensors and the mirror on the
barcode reader (see
Section 4.5 on page 4-7 )
4.1 Checking the Air Filters
Fans in the system controller, each power supply, and each drive carrier draw outside air
through filters located behind the air filter covers on the LRM and MEM. The filters help
keep dust and dirt from entering the library and degrading the performance of the tape
drives and media. To ensure the best reliability, periodically check and replace the air
filters.
To order replacement filters, see Section 1.6.2 on page 1-10 .
Important: The air filters help protect the library from large
contaminants but are not intended to keep the tape
drives clean. For best performance, clean the tape drives
according to the manufactu
rer’s recommendations.
X-Link automatically alerts users to check the air filters after the amount of time
specified by the Days until Air Filter Check library policy. Because filters should be
replaced more frequently in dusty environments, the recommended time between air filter
changes varies with the installation environment. When the XLS is first installed, inspect
the filters frequently. Then, as required, adjust the time specified for the Days until Air
Filter Check policy.
