Safety Guidelines

Laser Safety

Before you install SFP modules in a Cisco device or attempt to operate or service a Cisco device equipped
with SFP modules, you must read and observe the important safety information in this publication. Refer to
the Regulatory Compliance and Safety Information publication or the Site Preparation and Safety Guide
that supports your Cisco device for the complete list of translated safety warnings and agency approvals
that apply to your Cisco device.
The Cisco SFP Transceiver Modules are equipped with a Class 1 Laser, which emits invisible radiation.
Do not stare into open optical ports. These warnings apply to the Cisco SFP modules.
Warning: Class 1 laser product.
Warning: Because invisible laser radiation can be emitted from the aperture of the port when no
fiber is connected, avoid exposure to laser radiation and do not stare into open apertures.
Warning: Laser radiation is present when the system is open and interlocks bypassed.
Warning: Only trained and qualified personnel should be allowed to install, replace, or service this
equipment.

Guidelines for Handling SFPs

Use these guidelines when you work with SFPs:
Cisco SFP modules are static sensitive. Wear an ESD-preventive wrist strap that is connected to
the chassis in order to prevent ESD damage.
Cisco SFP modules are dust sensitive. Always store the devices with plugs installed in the optical
bores.
Do not remove and insert a Cisco SFP module more often than is necessary. Repeated romovals
and insertions of a Cisco SFP module can shorten its useful life.

Required Tools

You need these tools in order to install or remove the SFP transceiver:
Wrist strap or other personal grounding device to prevent ESD occurrences.
Antistatic mat or antistatic foam to set the transceiver on.
Fiber-optic end-face cleaning tools and inspection equipment.
Refer to these documents for complete information on how to inspect and clean fiber-optic
connections:
Inspection and Cleaning Procedures for Fiber-Optic Connections
Compressed Air Cleaning Issues for Fiber-Optic Connections

Install and Remove SFP Transceiver Modules

This installation section provides the installation instructions for the Cisco SFP Transceiver Modules. The
SFP Transceiver Modules are hot-swappable input/output (I/O) devices that plug into 100BASE and
1000BASE ports, which connects the module port with the fiber-optic or copper network.
You can use any combination of SFP modules that your Cisco device supports. The only restrictions are
each port must match the wavelength specifications on the other end of the cable and the cable must not
exceed the stipulated cable length for reliable communications.
