DANGER:
The OC-3c Single Mode (SM) and the STM-1 Single Mode (SM) modules
contain a laser-generating device, which emits a laser light beam from
the transmit port. This port is labeled TX on the module faceplate. When
the module is inserted into an operational AC 60 chassis, personal injury
may result from looking into, or near, either port. Personal injury may
also result from looking into, or near, the far end of a connected fiber
optic cable. For additional laser safety information, see Appendix B of
the
OC-3c Multi-Mode and Single-Mode Module Guide
, the
OC-3c Multi-
Mode and Single-Mode 1+1 APS Module Guide
, the
STM-1 Multi-Mode
and Single-Mode Module Guide
, and the
STM-1 Multi-Mode and Single-
Mode 1+1 MSP Module Guide

DANGER:
Interface lines connected to the Voice 2-Wire Office module (model
number 20N32) that exit the building premises must be connected to any
nationally recognized testing laboratory (NRTL) listed
telecommunications protection device that provides primary and
secondary protection. These protection devices provide overvoltage
protection to the Voice 2-Wire Office module interface lines.
!
DANGER:
Read all installation instructions before connecting the system to a
power source.
!
DANGER:
Do not work on the system, connect, or disconnect cables during periods
of possible lightning activity.
!
DANGER:
Do not perform any action that could create a possible hazard to others
or make the working environment and/or the equipment unsafe.
WARNING:
!
Be sure to cover all empty slots with blank faceplates to protect your
equipment.
WARNING:
!
This product relies on the building’s installation of short-circuit (over-
current) protection. Ensure that a fuse or circuit breaker no larger than
120 V ac, 15 A U.S. (240 V ac, 10 A international) is used on the phase
conductors (all current-carrying conductors).
WARNING:
!
Once the AC 60 chassis is operational (power is applied to the chassis)
and the OC-3c SM or STM-1 SM module is fully inserted into the chassis
backplane, use extreme caution during removal of the fiber optic cable
from one or both ports. Keep the protective port caps supplied with
these two types of modules nearby (for example, taped to the cable for
