INSTALLING OR OPERATING THESE MODULES.

The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This
control loo p el imina tes the need for main tenanc e check s or adj ustmen ts. The outp ut is fac tor y set, an d
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 Publica tio n 825 (Intern a tional Electrotech nical Co mmi ss ion).

• CENELEC EN 60825 (European Committee for Electrotechnical Standardiz ation).
When operating within their performance limitations, laser transceiver output meets the Class 1

accessible emission li mit of all thr ee s tandards. Cl as s 1 leve ls of laser radiation are no t considered
hazardous.

SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

LASER RADIATION AND CONNECTORS

When the connect or is in place, a ll laser radiat ion remains within the fiber. The maximum amount of
radiant power e xiting the fiber (u nder normal c ondition s ) 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 cm

Do not use optical instruments to view the laser output. The use of optical inst ruments to view
laser output increase s eye hazard. When vi ew ing the output opt ical port, power must be
removed from the network adapter.

CHAPTER 1

INTRODUCTION

This chapter describ es the features of the DLE2X-MA and DLE3X-MA
Interface Modules.

1.1 DLE2X-MA AND DLE3X-MA OVERVIEW

The DLE2X-MA and DLE3X-MA, shown in Figure 1-1, are interface
modules for the DLM6C-AA chassis.

The DLE2X-MA and DLE3X-MA are high-speed network switch
devices that support 802.1D switching (bridging) and 802.1Q switching.
Ports 25 and 26 of the DLE2X-MA support optional Fast Ethernet
Interface Modules and can provide uplinks to 100BASE-TX or
100BASE-FX Fast Ethernet netw orks. The DLE3X-MA is capable of
being equipped with a High Speed Interface Module (HSIM) that
provides for addi tional connectivity to other high speed net working
technologies such as Asychr onous Transfer Mode (ATM), Wide Area
Networks (WANs) and Fiber Distributed Data Interface (FDDI).

The DLM6C-AA can be used to connect individual high-bandwidth user
devices, such as workstations, and t o provide a central switching point for
multiple Ethernet segments using devices such as the HubSTACK or
other third party stac kable devices.

Figure 1-1 displays the DLE22-MA and DLE32-MA. The
DLE22-MA and the DLE23-MA are functionally identical, as are
the DLE32-MA and the DLE33-MA. The only difference being
that the DLE23-MA and DLE33-MA modules support RJ21
front panel connections.

10BASE-T compliant.

The DLE23-MA and DLE33-MA connect to Ethernet networks or
workstations through two RJ21 connectors on the front pa ne l. The se
connectors support 25 pair cable at lengths up to 100 meters. The ports
are IEEE 802.3 10BASE-T compliant.

The DLE2X-MA modules hav e two f ront pa nel slots (ports 25 and 26) for
optional Fast Ethernet Interface Modules to support an uplink to
100 Mbps Ethernet backbones or a high speed connection to a local
server.

The DLE3X-MA modules have one front panel slot for an optional High
Speed In te rface Module to provide for additional connectivi ty to other
high speed networking technologies such as ATM, WANs and FDDI.

1.1.2 Full Duplex Switched Ethernet

Each switched Ethernet port supports full wire-speed Ethernet
communications and can be configured to operate in Full Duplex
Switched Ethernet mode, which provides up to 20 Mbps of bandwidth.

The optional Fast Ethernet Interface Modules for the DLE2X-MA can
also be configur ed to operate in Full Duplex Switche d Ethernet mode,
which provides up to 200 Mbps of bandwidth.

1.1.3 SmartTr un k

The SmartT runk f eature a llo ws the user to se t a gr oup of DLE2X-MA and
DLE3X-MA interfaces, so they can share the traffic load an d effectively
increase the bandwidth between connected DLE2X-MA and

When the modules are connected to the netw ork and powered up,
Runtime IP Address Discovery (RAD) checks the modules for an IP
address. If one has not yet been assigned (module and DLM6C-AA
chassis IP addre ss set to 0.0.0.0), RAD checks to se e if any of the module
interfaces have a link. If so, RAD sends out Reverse Address Resolution
Protocol (RARP) and BootP requests to obta in an IP address from a
RARP or BootP server on the network.

The RAD requests start out a t an interval of one second. The interval then
doubles after every trans mission 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 RARP or BootP
server, or an IP address is entere d using Local Management.

1.1.10 Local Management Features

Local Management provides the tools that allow management of the
DLE2X-MA and DLE3X-MA, the Fast Ethernet Interface Modules, the

Chapter 3: Installation

3.5.4 Connecting a Fiber Optic Segment
to the DELFX-UI and DELF3-UI

The DELFX-UI and DELF3-UI have an SC style net wor k port (see
Figure 3-7). Cabletron Systems suppli es fiber optic cable that uses SC
style connectors that are keyed to ensure proper crossing over of the
transmit and receive fibers.

An odd number of crossovers (preferably one) must be

!

maintained between devices so that the transmit port of one
device is connected to the receive port of the other device and
vice versa.

If the fiber optic cable being used has SC style connectors that
do not resemble MIC style connectors, or has SC connectors
on one end and a diff erent type on the other , such as ST
connectors, ensure that the proper crossing ov er occurs.

Fiber Optic Network Connection

1. Remove the protective plastic covers from the fiber optic por ts on the

applicable port on the module and fr om the ends of the conne ctors.

The DELF3-UI uses Class 1 lasers. 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.

Do not touch the ends of the fiber optic strands, and do not let

!

the ends come in contact with dust, dirt, or other contaminants.
Contamination of the ends causes problems in data
transmissions. If the ends become contaminated, clean them
with alcohol using a soft, clean, lint-free cloth.

2. Insert one end of the SC co nnector into the DELFX- UI or DELF3-UI

installed in the DLE2X-MA. See Figure 3-7.

3. At the other end of the fiber optic cable, atta ch the SC connector to the

other device.

Subnet Mask (Modifiable)

When a valid IP address is assigned, the Subnet Mask field
automatically enters the default mask that corresponds with
class of IP entered in the IP Address field. Some firmware
revisions do support changing the chass is subnet mas k from
the default value. Refer to your Release Notes to ensure that
the Subnet Mask is a modifiable field.

Displays the subnet mask for the chassis. A subnet mask “masks out” the
network bits of the IP a ddress by setting t he bi ts in the mas k to 1 when the
network treats the corresponding bits in the IP address as part of the
network or subnetwor k address, or to 0 if the corresponding bit identifies
the host. The DLM6C-AA chassis automatically uses the default subnet
mask that corresponds to the IP class tha t was entered in the IP address
field. S ection 5.7.2, Setting the S ubnet Mask describes how to change the
subnet mask from the default value.

5.11 PORT REDIRECT FUNCTION SCREEN

The Port Redirect Function screen may not be available
depending on the operational mode that has been set for the
chassis. Refer to your Release Notes to see what operational
modes support the Por t Redirect Funct ion. Refer to
Section 5.7.7,
on configuring the operational mode of all t he modules installed
in the chassis.

Setting the Operational Mode

The Port Redirect Function screen, Figure 5-13 , allows the user to set
each one of the modules in the chassis (1 through 5), and the ports of the
corresponding module insta lled, as a source or destination port. A port
can be set to have one or more destination ports and chassis module slot
numbers. For example, port 1 in module (slot) 1 can be set as a source
port with three destinations, ports 2, 3, and 4 in module (slot) 3. Traffic
from port 1 in module 1 is then automati cally redirected to ports 2, 3, and
4 in module 3. Port 1 in module 1 can also serve as a destinati on port for
other ports and mod ules. The port r edire ct f unction is e xtre mely useful f or
troubleshooting purposes, as it allows traffic to be sent to a particular
port(s) where, with the use of an analyzer or RMON probe, all current

, for instructions

traffic from the source port( s) can be examined.

The module number corresponds to the slot number in which
the module resides in the DLM6C-AA chassis (1 through 5).

Although traffic from the source port (including, if desired,
errored frames) is sent to the destination port, normal switching
is still performed for all frames on the source port.

Access the Port Redirect Funct ion screen from the Chassis Menu screen
by using the arrow keys to highlight the PORT REDIRECT
FUNCTION menu item and pressing ENTER. The Port Redirect
