Safety Information

Class 1 Laser Transceivers

The single mode interface modules use Class 1 laser transceivers. 

Read the following safety information before installing or operating these modules.

The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the 

need for maintenance checks or adjustments. The output is factory set, and does not allow any user adjustment. Class 1 Laser 

transceivers comply with the following safety standards:

• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).

• IEC Publication 825 (International Electrotechnical Commission).

• CENELEC EN 60825 (European Committee for Electrotechnical Standardization).

When operating within their performance limitations, laser transceiver output meets the Class 1 accessible emission limit of all 

three standards. Class 1 levels of laser radiation are not considered hazardous.

When the connector is in place, all laser radiation remains within the fiber. The maximum amount of radiant power exiting the 

fiber (under normal conditions) is -12.6 dBm or 55 x 10-6 watts.

Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The maximum 

radiance from the optical port (under worst case conditions) is 0.8 W cm-2 or 8 x 103 W m2

 sr-1. 

Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye 

hazard. When viewing the output optical port, power must be removed from the network adapter.

Safety Compliance

This chapter introduces the Enterasys 800-Series Fast/Gigabit Ethernet switches.

Overview

The Enterasys 800-Series Fast/Gigabit Ethernet switches are store and forward switches that can 

be adapted and scaled to help meet your network requirements. 

You can also use a redundant power supply with these switches to help prevent downtime due to 

an internal power supply failure in the switch or AC power source.

You can install the switches on a flat surface or into a standard 19-inch rack, and configure the 

switch functions using the Web User Interface, Command Line Interface commands, and/or 

SNMP.

The Enterasys 800-Series switch can connect to Ethernet networks or workstations through RJ45 

connectors, SFP ports, or Gigabit Ethernet ports, depending on your model’s configuration. The 

SFP ports support optional pluggable transceivers, which are hot swappable. 

For pluggable transceiver compatibility and specifications, refer to the datasheet at

http://www.enterasys.com/products/transceivers-ds.pdf.

Switch Configuration Using CLI Commands

The CLI commands enable you to perform complete switch configuration management tasks. For 

CLI command set information and how to configure the switch, refer to the Enterasys 800-Series 

CLI Reference.

Fan Operation on the 800-Series

The 800-Series switches support three unique fan control mechanisms.

1. The 08G20G2-08, 08G20G4-24, and 08H20G4-48 switches will turn on their fans with the initial 

boot-up procedure and will turn off their fans when the room temperature is below 32° C 

(89.6° F). If the room temperature rises above 36° C (96.8° F), these switches’ internal fans will 

turn on again. 

2. The 08G20G4-24P, 08G20G4-48, 08G20G4-48P, 08H20G4-24P, and 08H20G4-48P switches will 

never turn their fans off. Instead their fans will toggle between high and low revolution 

speeds. During the initial boot-up procedure or when the room temperature is above 36° C 

(96.8° F), these fans will operate at a high revolution speed. If the room temperature falls 

below 32° C (89.6° F), then these switches’ fans will operate at a low revolution speed.

3. The 08G20G2-08P switch will automatically turn the internal fans off when the PoE feature 

provides a load within 60W and the room temperature is below 30° C (86° F). During the 

initial boot-up procedure, when the PoE load is over 60W, or when the room temperature is 

above 36° C (96.8° F), the switch’s fans will automatically turn on.

The 08H20G4-24 is the only switch in this series that can operate between 0° C (32° F) and 50° C 

(122° F) without the need for internal fans.
