Safety Instructions
When a connector is removed during installation, testing, or servicing, or when an energized fiber is broken, a risk
of ocular exposure to optical energy that may be potentially hazardous occurs, depending on the laser output
power. The primary hazards of exposure to laser radiation from an optical-fiber communication system are:
•Damage to the eye by accidental exposure to a beam emitted by a laser source.
•Damage to the eye from viewing a connector attached to a broken fiber or an energized fiber.
Front Panel
The switch front panel provides all the connections, controls and LED indicators as shown and described below.

Transition Networks SISGM1040-284-LRT Install Guide

The front panel LEDs provide switch status as follows:
Power LEDs (P1 and P2): indicate whether the switch is powered up correctly.
SYS (System) LED: indicates if the system is ready or not.
ALM (Alarm) LED: indicates if the system is operating normally.
RM (Ring Master) LED: indicates if Ring Master(s) or Slave is enabled.
RC (Rapid Chain) LED: indicates the status of the Rapid-Chain.
Port Status LEDs: indicate the current status of each port. Check these LEDs to
determine the port status.
