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.
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 10-6 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.

Overview
The 2H23-50R is a high speed network repeater/switch device that
provides four Ethernet networks and four Fast Ethernet networks (RJ21
MicroLANs, CONN 1 through CONN 4) and two slots (5 and 6) for
optional Fast Ethernet Interface Modules. The RJ21 connectors each
consist of 12 repeater ports that are able to reside on the Ethernet
(10 Mbps) or the Fast Ethernet (100 Mbps) network. Each Ethernet and
Fast Ethernet network supports 802.1D switching (bridging), Cabletron
Systems SecureFast Switching Virtual Network technology and IEEE
802.1Q Port Based Virtual Local Area Networks (VLANs). Slots 5 and 6
support Fast Ethernet Interface Modules to provide uplinks to
100BASE-TX or 100BASE-FX Fast Ethernet Networks.
The 2H33-37R is a high speed network repeater/switch device that
provides three Ethernet networks and three Fast Ethernet networks (RJ21
MicroLANs, CONN 1 through CONN 3) and one slot for an optional
High Speed Interface Module (HSIM). The RJ21 connectors each consist
of 12 repeater ports that are able to reside on the Ethernet (10 Mbps) or
the Fast Ethernet (100 Mbps) network. Each Ethernet and Fast Ethernet
network supports 802.1D switching (bridging), Cabletron Systems
SecureFast Switching Virtual Network technology and IEEE 802.1Q Port
Based Virtual Local Area Networks (VLANs). The 2H33-37R can be
equipped with an optional HSIM to provide additional connectivity to
other high speed networking technologies such as Asynchronous Transfer
Mode (ATM), Fiber Distributed Data Interface (FDDI), and Wide Area
Network (WAN).
The device may be used as a tabletop unit or can be installed in a standard
19-inch rack using the supplied rack mounting hardware.
The 2H23-50R and 2H33-37R have two power supplies with automatic
voltage sensing that allows operation using 100–125 or 200–240 Vac,
50/60 Hz. The power supplies load share 50% (+/-5%) of the power
required by the device. If one power supply fails, the remaining power
supply assumes the entire load of the device without interruption to
network traffic. Each power supply module supports its own ac input
connection, which allows the user to connect each power supply to a
different ac power circuit.
2H23-50R/2H33-37R User’s Guide1-3
Chapter 1:
Introduction
1.3.1Connectivity
The 2H23-50R or 2H33-37R connect to Ethernet/Fast Ethernet networks
or workstations through RJ21 ports on the front panel. Each port supports
a 25-pair cable at lengths up to 100 meters (each pair must be Category 5
compliant with an impedance of 85 to 111 ohms). The ports are IEEE
802.3 10BASE-T and IEEE 802.3u 100BASE-T compliant.
The 2H23-50R has two front panel slots (5 and 6) for optional Fast
Ethernet Interface Modules to support an uplink to Fast Ethernet
backbones or a high speed connection to a local server.
The 2H33-37R has a slot for an optional HSIM to provide additional
connectivity to high speed networking technologies such as ATM, FDDI,
and WANs.
Cables available for 100BASE-TX operation include:
The optional Fast Ethernet Interface Modules for the 2H23-50R can be
configured to operate in Full Duplex Switched Ethernet mode, which
provides 200 Mbps of bandwidth.
1.3.3Auto-Negotiation
The repeater ports and Fast Ethernet Interface Modules can auto-negotiate
the type of connection required to provide a link to another device.
During Auto-Negotiation, two devices automatically exchange
information “telling” each other what their operating capabilities are. The
Auto-Negotiation feature targets the maximum capabilities that can be
reached between the two devices. For example, an FE-100TX Fast
Ethernet Interface Module in a 2H23-50R can adjust to 100 Mbps when
the device on the other end of the connection can also adjust to 100 Mbps.
If the device on the other end of the connection can only operate at
10 Mbps, then the FE-100TX simply adjusts to 10 Mbps operation.
1-42H23-50R/2H33-37R User’s Guide
Overview
When Auto-Negotiation is supported at both ends of a link, the two
devices dynamically adjust to full or half duplex operation based on the
maximum capability that can be reached between the two devices. If the
device connected to the FE-100TX cannot auto-negotiate, the FE-100TX
Fast Ethernet Interface Module operates according to the capabilities of
the other device.
1.3.4SmartTrunking
SmartTrunk, also referred to as SmartTrunking, is Cabletron Systems’
terminology for load balancing or load sharing. SmartTrunk technology
provides an easy-to-implement mechanism to group, or aggregate,
multiple physical links together to scale the backbone bandwidth beyond
the limitations of a single link. All links are user-configurable so
administrators can scale the backbone bandwidth by adding SmartTrunk
links. The SmartTrunk benefits are as follows:
•
All purchased bandwidth is used.
•
Distributed, resilient links increase reliability and performance.
•
Multiple technologies are supported within a single trunk for
maximum flexibility.
For more information about SmartTrunk, refer to the Cabletron Systems
SmartTrunk User’s Guide
.
1.3.5Runtime IP Address Discovery
This feature enables the 2H23-50R or 2H33-37R (device) to
automatically accept an IP address from a Boot Strap Protocol (BootP) or
Reverse Address Resolution Protocol (RARP) server on the network into
NVRAM without requiring a user to enter an IP address through Local
Management.
When the device is connected to the network and powered up, Runtime IP
Address Discovery (RAD) checks the device for an IP address. If one has
not yet been assigned (2H23-50R IP address set to 0.0.0.0), RAD checks
to see if any of the device’s interfaces have a link. If so, RAD sends out
RARP and BootP requests to obtain an IP address from a server on the
network.
2H23-50R/2H33-37R User’s Guide1-5
Chapter 1:
Introduction
The RAD requests start out at an interval of 1 second. The interval then
doubles after every transmission until an interval of 300 seconds is
reached. At this point, the interval remains at 300 seconds. The RAD
requests continue until an IP address is received from a server, or an IP
address is entered using Local Management.
1.3.6Management
Management of the 2H23-50R or 2H33-37R is accomplished using
SNMP compliant management tools for in-band Local Management.
Out-of-band Local Management is provided through the RJ45 COM port
on the front panel using a VT100 terminal or a VT100 terminal emulator.
In-band remote management is possible through any SNMP compliant
Network Management Software.
Local Management provides the ability to manage the 2H23-50R and
2H33-37R and any of the optional Fast Ethernet Interface Modules
installed in slots 5 and 6 of the 2H23-50R, or an optional High Speed
Interface Module (HSIM) in a 2H33-37R.
The associated HSIM user’s guide provides detailed information about
the HSIM Local Management.
1.3.7Switching Options
The 2H23-50R and 2H33-37R provide 802.1D switching, 802.1Q
switching or SecureFast Switching Virtual Network Services between all
of the front panel interfaces including Fast Ethernet Interface Modules
installed in a 2H23-50R or an HSIM installed in a 2H33-37R.
IEEE 802.1Q switching and SecureFast switching allow for future
migration to Virtual Network technologies without requiring the
replacement of existing equipment.
