Hardware Maintenance for Models 9520, 9520-ILM, and 9820-45M

iMarc SLV rack-mounted units are designed for years of trouble-free service.
There are actions you can take to further reduce the likelihood and amount of
down time:

Cleaning the Front Panel Assembly

The substantial airflow through the iMarc unit's four fans may cause dust to collect
on the outside of the front air vents. When dust becomes visible at the air vents,
run the brush attachment of a vacuum cleaner gently over the front panel to
remove it.
In extremely dusty environments it may be necessary to remove the front panel
assembly to clean the blades of the fans. Refer all service to qualified personnel.
The procedure may be performed while the unit is running.
