9.2 Maintenance
Keep the fiber ports clean and free of dust. No other periodic maintenance of the Uni-
son equipment is required.
To clean the fiber ports:
You can clean the Hub’s fiber ports using canned compressed air or isopropyl alcohol
and cotton swabs.
Considerations:
• If you use compressed air:
• The air must be free of dust, water, and oil.
• Hold the can level during use.
• If using isopropyl alcohol and foam-tipped swab:
• Use only 98% pure or more alcohol.
Procedure using compressed air:
1. Remove the connector’s dust cap.
2. Spray the compressed air away from the unit for a few seconds to clean out the
nozzle and then blow dust particles out of each fiber port.
Procedure using isopropyl alcohol:
1. Remove the connector’s dust cap.
2. Dip a 2.5mm lint-free, foam-tipped swab in isopropyl alcohol and slowly insert
the tip into the connector.
3. Gently twist the swab to clean the connector.
4. Insert a dry swab to dry the connector.
Additionally, you can use compressed air after the alcohol has completely evapo-
rated.
