NOTE: Harmonic recommends that you always disable the laser output before disconnecting any optical fibers. if you suspect that the optical connector of an HOA 7320 may have been exposed to contamination (by a dirty fiber cable connector. Never operate a unit that has a broken fiber or a disconnected fiber connector. The optical output power is limited to 15 dBm while the HOA 7320 is in low output power mode. CAUTION: Improper cleaning of an optical connector can do more harm than good. In addition.5 Maintenance This chapter describes how to: • • • Place the HOA 7320 in low output power mode Clean fiber optic connectors Replace the fan filter in the HOA 7320 5. Dirty optical connectors are the leading source of poor performance in an optical fiber network. before connecting them to an optical device. you should properly clean the HOA 7320 optical connector before connecting the optical fiber.
