Install and Operation Guide

6-4. Optic Module Installation Cautions

It is strongly recommended that you do not install or remove the SFP module with/without fiber-

optic cables attached to it because of the potential of damaging the cable, the cable connector, or

the optical interfaces in the SFP module. Disconnect all cables before removing or installing an SFP

module. Removing and inserting an SFP module can shorten its useful life, so you should not remove

and insert SFP modules any more often than is absolutely necessary.

6-5. Electrical Safety Advisory

Telephone companies report that electrical surges, typically lightning transients, are very destructive

to customer terminal equipment connected to AC power sources. This has been identified as a major

nationwide problem. Therefore it is advised that this equipment be connected to AC power through

the use of a surge arrestor or similar protection device.
