FCC NOTICE

This device complies with Part 15 of the FCC rules. Operation is
subject to the following two conditions: (1) this device may not
cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.

NOTE: This equipment has been tested and found to comply with
the limits for a Class A digital device, pursuant to Part 15 of the FCC
rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
commercial environment. This equipment uses, generates, and can
radiate radio frequency energy and if not installed in accordance with
the operator’s manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is
likely to cause interference in which case the user will be required to
correct the interference at his own expense.

WARNING: Changes or modifications made to this device which
are not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.

INDUSTRY CANADA NOTICE

This digital apparatus does not exceed the Class A limits for radio
noise emissions from digital apparatus set out in the Radio
Interference Regulations of the Canadian Department of
Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques
dépassant les limites applicables aux appareils numériques de la class
A prescrites dans le Règlement sur le brouillage radioélectrique
édicté par le ministère des Communications du Canada.

Notice

VCCI NOTICE

This is a Class A product based on the standard of the Voluntary
Control Council for Interference by Information Technology
Equipment (VCCI). If this equipment is used in a domestic
environment, radio disturbance may arise. When such trouble occurs,
the user may be required to take corrective actions.

CLASS A ITE NOTICE

WARNING: This is a class A product. In a domestic environment
this product may cause radio interference in which case the user may
be required to take adequate measures.

SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

The VH-2402-L3 24-port switch uses Class 1 Laser transceivers.
Read the following safety information before installing or operating
these modules.

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).

9033693-01 v

• 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.

SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

LASER RADIATION AND CONNECTORS

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

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

–2

or 8 x 10 3 W m 2 sr -1 .

cm

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
switch.

watts.

WARNING: FIBER OPTIC PORT SAFETY

When using a fiber optic port, never look at the transmit laser
while it is powered on. Also, never look directly at the fiber TX
port and fiber cable ends when they are powered on.

AVERTISSMENT: PORTS POUR FIBRES OPTIQUES -

SÉCURITÉ SUR LE PLAN OPTIQUE

Ne regardez jamais le laser tant qu'il est sous tension. Ne
regardez jamais directement le port TX (Transmission) à fibres
optiques et les embouts de câbles à fibres optiques tant qu'ils
sont sous tension.

Product Overview

This chapter provides the following information:

• Product Description

• Features

• Front and Rear Panel Component Descriptions

• Feature Summaries

• Application Example

Description

This installation guide describes Enterasys Networks’
Vertical Horizon VH-2402-L3 Fast Ethernet switch. The
switch provides 24 10Base-T/100Base-TX ports, plus
one slot for optional slide-in 1000Base-SX 1000Base-T
and GBIC modules. The switch features a built in
SNMP-based Management agent. The VH-2402-L3
support both Layer 2 as well as Layer 3 functionality.

Layer 3 Switching

Layer 3 switching is an integration of two proven
technologies: switching and routing. In fact, Layer 3
switches are running the same routing routines and
protocols as traditional routers. The main difference
between traditional routing and Layer 3 switching is the
addition of a group of Layer 2 switching domains and
the execution of routing routines for most packets via
an ASIC – in hardware instead of software.
