SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
THE FE-100F3 FAST ETHERNET INTERFACE MODULE, FPIM-05 AND
FPIM-07 FDDI PORT INTERFACE MODULES, AND APIM-29 ATM
PORT INTERFACE MODULE 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.
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.

2H22-08R Overview
1.3 2H22-08R OVERVIEW
The 2H22-08R is a Fast Ethernet standalone device that has six RJ45
switched ports and two optional Fast Ethernet Interface Module ports
(100BASE-TX, 100BASE-FX, and 100BASE-F3) that provide twisted
pair, multimode, and single mode fiber optic cabling connectivity.
PWR
CPU
RESET
2H22-08R
COM
The 2H22-08R supports traditional IEEE 802.1d switching (bridging),
IEEE 802.Q switching, and Cabletron Systems S
Virtual Netw ork technology. The 2H22-08R is used to connect individual
high-bandwidth user devices, such as workstations, and provide a central
switching point for multiple 10/100 Mbps Fast Ethernet segments.

1.3.1 Auto-Negotiation
Twisted Pair ports on the 2H22-08R can auto-negotiate the type of
connection required to provide a link to another device. During
Auto-Negotiation, two devices automatically exchange information
concerning their operating capabilities. The Auto-Negotiation feature
targets the maximum capabilities between the two devices. For example,
the 2H22-08R adjusts to 100 Mbps when the device on the other end of
the connection can adjust between 10 Mbps or 100 Mbps. If the device on
the other end of the connection can only operate at 10 Mbps, then the
2H22-08R adjusts to 10 Mbps operation.
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 2H22-08R cannot auto-negotiate, the 2H22-08R
interface operates according to the capabilities of the other device.
2H22-08R SmartSwitch 2208 User’s Guide Page 1-3
Chapter 1:
Introduction
1.3.2 Connectivity
The 2H22-08R connects to Ethernet networks or workstations through six
RJ45 ports on the front panel. These ports support Category 5 unshielded
and shielded twisted pair cables of lengths up to 100 meters. These ports
are IEEE 802.3u 100BASE-TX compliant.
The 2H22-08R has two front panel slots (ports 7 and 8) for optional Fast
Ethernet Interface Modules (FE-100TX, FE-100FX, and FE-100F3) to
support an uplink to 100 Mbps Fast Ethernet backbones or a high speed
connection to a local server using twisted pair, multimode or single mode
fiber optic cabling.
1.3.3 Runtime IP Address Discovery
This feature enables the 2H22-08R to automatically accept an IP address
from a Boot Strap Protocol (BootP) server on the network into NVRAM
without requiring a user to enter an IP address through Local
Management.
When the 2H22-08R is connected to the network and powered up,
Runtime IP Address Discovery (RAD) checks the 2H22-08R for an IP
address. If one has not yet been assigned (2H22-08R IP address set to
0.0.0.0), RAD checks to see if any of the 2H22-08R interfaces have a link.
If so, RAD sends out Reverse Address Resolution Protocol (RARP) and
BootP requests to obtain an IP address from a BootP server on the
network.
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 BootP server, or
an IP address is entered using Local Management.

2H22-08R Overview
1.3.4 Remote Monitoring (RMON)
The 2H22-08R supports all Ethernet RMON groups, which include
Statistics, Alarms, Ev ents and History as the default groups enabled on all
ports, and Capture, Filter, and Host as the groups that are off by default.
Cabletron Systems RMON Actions is a vendor-specific extension of
RMON and provides the ability to set an “Action” on any SNMP MIB
variable. The Action can be triggered by any RMON Event and/or Alarm.
The Action can be, for example, to turn a MIB-2 interface off if a
broadcast threshold is crossed.

panel interfaces including Fast Ethernet Interface Modules. S
Switching Virtual Network Services between all of the front
ECUREFAST
Switching and IEEE 802.1Q allows for migration to Virtual Network
technologies without requiring the replacement of existing equipment.
1.3.6 Standards Compatibility
The 2H22-08R provides IEEE 802.1, 802.1u, 802.1D and DEC Spanning
Tree Algorithm (STA) support to enhance the overall reliability of the
network and protect against “loop” conditions. The 2H22-08R supports a
wide variety of industry standard MIBs including RFC 1213 (MIB II),
RFC 1757 (RMON), RFC 1493 (Bridge MIB), and RFC 1354 (FIB MIB).
A full suite of Cabletron Systems Enterprise MIBs provides a wide array
of statistical information to enhance troubleshooting.
1.3.7 Year 2000 Compliant
The 2H22-08R has an internal clock that can maintain the current time
and date beyond the year 1999.
1.3.8 LANVIEW Diagnostic LEDs
The various conditions of the LANVIEW diagnostic LEDs serve as
important troubleshooting aids. They provide an easy way to observe the
transmit and receive status of individual ports and overall network
operations such as system status, switching configuration, and Fast
Ethernet channel usage.

Chapter 1:
Introduction
1.4 LOCAL MANAGEMENT
Management of the 2H22-08R is accomplished using Local Management
tools or remote Simple Network Management Protocol (SNMP)
management stations. Out-of-band Local Management is accessible
through the RS232 COM port on the front panel using a VT100 terminal,
or a remote VT100 terminal emulator via a modem connection, and
in-band via a Telnet connection. In-band remote management is possible
through any SNMP compliant Network Management Software.
Local Management provides the tools to manage the 2H22-08R, and its
two Fast Ethernet Interface Modules. It also allows the following tasks to
be performed:
•
Assign an IP address and subnet mask to the 2H22-08R.
•
Select a default gateway and default interface.
•
Control local and remote access.
•
Designate workstations to receive SNMP traps from the 2H22-08R.
Chapter 5
provides detailed information about Local Management of the
2H22-08R, and its two optional Fast Ethernet Interface Modules. Local
Management also provides the features detailed in Section 1.4.1 through
Section 1.4.4.
1.4.1 Broadcast Suppression
Broadcast Suppression allows a user to set a desired limit of receive
broadcast frames per port/per second to be forwarded out of the other
ports on the module up to the set limit. Any broadcast frames above this
specified limit are dropped. In the event that broadcast frames are being
suppressed, multicast and unicast frames continue to be switched without
suppression.

Local Management
1.4.2 Port Redirect Function
The port redirect function, also referred to as “Port Mirroring,” is a
troubleshooting tool used to map traffic from a single source port or
multiple source ports to Destination ports(s) within the chassis. This
feature functions at the bit level, which allows all packets, including, if
desired, those with errors, to be copied and sent to an analyzer or RMON
probe that appears as if it is directly connected to the LAN segment of the
source port(s).
1.4.3 Full Duplex Switched Ethernet (FDSE)
Each switched Fast Ethernet port on the 2H22-08R supports 10/100 Mbps
operation and can be configured to operate in Full Duplex Switched
Ethernet (FDSE) mode. FDSE allows each Fast Ethernet port to provide
up to 200 Mbps of aggregate throughput bandwidth.
1.4.4 SmartTrunk
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.
SmartTrunking on the 2H22-08R is available to group the optional Fast
Ethernet Interface Module ports 7 and 8.
For more information about SmartTrunk, refer to the Cabletron Systems
SmartTrunk User’s Guide.
