When handling modules, wearan antistatic discharge wrist strap to prevent damage to electronic components. Placemodules in antistatic packing material when transporting or storing. When working onmodules, always place them on an approved antistatic mat that is electrically grounded.Table 3 shows the configuration codes for the GPON 452/454. The GPON 452/454 is NRTLlisted to the applicable UL standards. The GPON 452/454 is intended for deployment in theOutside Plant (OSP) at locations where the NEC applies (for example, Customer Premises)and is intended to be installed by trained service personnel.This device complies with Part 15 of the FCC rules.
