Cleaning a WCS Subrack Filter Module
The Filter Modules are reusable, and can be cleaned with a brush, vacuum, or water. If water is used, as much
dust as possible should be removed before getting the Filter Module wet. Figure 17 shows examples of a clean
and a dirty Filter Module.

Installing a WCS Subrack Filter Module
To install a cleaned or new Filter Module, slide the filter into its slot and press firmly until its edge is aligned
with the front faceplate of the WCS Subrack chassis and cannot be pushed in any further.
When cleaning a Filter Module, take care so you do not damage the EMI gasket at the front of the filter
frame. If the Filter Module becomes damaged and cannot be reinstalled, contact your local CommScope
sales representative to order a new Filter Module (PN 7700691-xx).
Do not clean the Filter Module with water in the same vicinity as the WCS Subrack or other electronics.
Wet conditions increase the potential for receiving an electrical shock when installing or using electrically
powered equipment. Make sure the Filter Module is completely dry before replacing it in the WCS
Subrack chassis.
