1INTRODUCTION
This field guide provides detailed information about the hardware components comprising the
CALIENT S320 Optical Circuit Switch (OCS).
Topics covered herein include safety precautions for installing, using and maintaining the switch;
an overview of OCS functionality and physical architecture, including precise descriptions of the
LEDs and physical interfaces located on the front and rear of the OCS chassis; and step-by-step
procedures for unpacking and installing a new S320 OCS.
This document also provides system specifications for regulatory, reliability, space, optical and
environmental requirements, as well as CALIENT part numbers for ordering additional systems
or hardware components that may eventually need replacement (e.g., fan filter).

2SAFETY SUMMARY
This Safety Summary reviews specific safety precautions to observe when installing, operating
or working around the S320 OCS.
When preparing to install the S320 OCS, review the following list to ensure a safe installation:
If a site survey was performed (recommended), review the completed site survey sheet
for accurate site information.
Review the safety precautions, notes and warnings contained throughout this manual.
Observe all weight cautions related to handling equipment. Ensure that adequate
personnel and resources are available to lift and transport the switch during installation.
Locate power sources and observe all safety precautions related to connecting and
applying electrical power to the switch.
Implement all electrostatic discharge (ESD) prevention measures when handling the
S320 OCS.
Inspect the site for sources of laser light and take all applicable precautions when near
such sources.
Observe all recommended precautions when moving and handling hazardous materials
such as compressed gas and alcohol.
Exercise the prescribed cautions when handling and cleaning optical fiber.
2.1 Laser Safety
It is especially important to observe the proper precautions when working with or around
lasers. The following subsections describe the potential risks associated with laser technology
and the recommended procedures for using it safely.
2.1.1 General Precautions
The S320 OCS switches coherent (laser) light between input and output optical-fiber
terminations. The range of the light wavelengths passed through the equipment is outside the
visible spectrum. Because the unaided human eye cannot detect the presence of this light, the
light can pose a serious health hazard.
If the hazard is not mitigated through the use of proper safety equipment and the observance
of safety precautions, blindness can result. This section presents the general safety precautions
that must be observed by personnel working on or around the S320 OCS to reduce or eliminate
the laser radiation hazard.

Use of controls, adjustments or procedures other than those specified in this
guide could result in hazardous radiation exposure.
The S320 OCS can redirect the laser energy supplied by any one of the input
fiber-optic cables to any one of the output fiber-optic cables. To avoid injury, all of
the switch’s optical connectors must either be attached to a fiber-optic cable that
is part of a closed optical system, or capped with the supplied connector covers.
Under no circumstance should attempts be made to operate this equipment with
a fiber-optic connector that is uncapped or disconnected from a closed optical
communication system fiber-optic cable.
All service to this device that requires removal of the housing panel must be
performed by the manufacturer or its authorized agent(s). Note: None of the
repairs described in this guide require removal of the housing panel.
Personnel working near any equipment carrying optical traffic may not be aware of possible
exposure to light radiating from uncovered connectors of the equipment.
If the S320’s connectors are not capped, light might escape from them and cause physical
damage to personnel. To avoid potential harm from exposure to light, always practice the
following safety measures:
Always keep fiber cables connected to all of the S320 Optical Circuit Switch connectors,
whether or not the fiber termination is providing an active cross-connection. If a cable is
not connected to a connector, be sure the connector is capped. This prevents accidental
exposure to a light source, and it also helps to prevent physical contamination of the
connector’s fiber-optic surfaces.
Never look directly into a fiber end or into any optical connector. There is no warning
when the connector is connected to a light source.
Wear the appropriate laser safety glasses when a laser source may be present. When
evaluating safety glasses, always consider the laser power, wavelength and the
manufacturer class warnings for the laser device.

2.1.2 Laser Sources
The S320 Optical Circuit Switch generates Class 1 coherent (laser) light at 1310 nm wavelength
and -5.5 dBm. It also passes higher-powered laser light from external sources. The S320 Optical
Circuit Switch passes laser radiation through its fiber terminations when traffic-carrying fibers
are connected to the switch.
2.1.2.1 Class 1 Laser
The S320 Optical Circuit Switch uses a Class 1 laser internally as a test source. Light from this
laser could potentially be available at a fiber termination.
The S320 OCS is certified as a Class 1 laser product per the requirements of the U.S.
Federal Product Performance Standard for Laser Products contained in the regulations
in 21 CFR 1040.10. Class 1 laser products are not considered to be hazardous;
however, lasers more powerful than Class 1 may be connected to the S320 OCS.
Although the S320 OCS has no laser sources higher than Class 1, the total optical
power through the equipment—and potentially available at any one of the fiber
terminations, split-out cable connectors, patch-panel cables or patch-panel coupling
sleeves—could aggregate to the level of a Class 4 (highly hazardous) source.
2.2 Electrostatic Discharge
Components that contain integrated circuits can be damaged by static electricity. Static
electricity potentials develop through the movement of human bodies, and are released as
Electrostatic Discharges (ESDs) whenever they come in contact with other objects. Dry air
allows greater static charges to accumulate. However, static electricity potentials high enough
to damage circuits can occur in any environment, so taking precautions against ESD is
imperative when working around the S320.
The ESD symbol shown here appears on packaging and other items as a reminder to
take the necessary precautions to prevent electrostatic damage to the S320 OCS.
