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 elimina te s the need for main ten ance check s or adjust men ts. The out p ut is fac to ry 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 Publicatio n 825 (Interna tio nal Electrote c hnica l Co mmi ssion ).

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

accessible emiss ion limit of all three standard s . 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 las er radiation remains w ithin the fiber. The maximum amount of
radiant power exit ing the fib er (under normal condition s ) i s -1 2.6 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 vie w th e laser output. The use of optical instruments to view
laser output increases eye hazard. When viewing the output optica l port, power must be
removed from the network adapter.

CHAPTER 1

INTRODUCTION

This chapter describes 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 100BAS E-TX or
100BASE-FX Fa st Ethernet networks. The DLE3X-MA is capable of
being equipped with a High Speed Interface Module (HSIM) that
provides for additional connectivity to other high speed networking
technologies such as Asychronous 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 w orkstations, a nd to provi de a central switching poin t f or
multiple Ethernet se gments using devices such as the HubSTACK or
other third party stackabl e 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.

1.1.1 Connectivity

The DLE22-MA and DLE32-MA connect to Ethernet networks or
workstations through 24 RJ4 5 ports on the front panel. These ports
support UTP connections up to 100 meters. The ports are IEEE 802. 3
10BASE-T compliant.

The DLE23-MA and DLE33-MA connect to Ethernet networks or
workstations through two RJ21 connectors on the front panel. These
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 fro nt panel 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 Inte rface Module to provide for additional connectivity to other
high speed networking techn ologies such as ATM, WANs and FDDI.

1.1.2 Full Duplex Switched Ethernet

Each switched Ethernet port suppo rt s 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 Ethern et Interface Modules for the DLE2X-MA can
also be configured to operat e in Full Duplex Switched Ethernet mode,
which provides up to 200 Mbps of bandwidth.

1.1.3 SmartTrunk

The SmartTr unk featu re allows the user to set a group of DLE2X-MA and
DLE3X-MA interfaces, so they can share the traffic load and effectively
increase the bandwidth between connected DLE2X-MA and
DLE3X-MAs or other devices supp ort ing the SmartTrunk feature. For
example, Ports 25 and 26 of the DLE2X-MA could be grouped to provide
a 200-Mbps uplink.

DLE22-MA, DLE32-MA, DLE23-MA and DLE33-MA User’s Guide 1-3

Chapter 1: Introduction

1.1.4 Management

Management of the DLE2X-MA and DLE3X-MA is accomplished using
Local Management tools or remote SNMP management stations. Local
Management is accessible through the RS232 COM port on the front
panel using a local VT100 terminal, or a remote VT100 terminal via a
modem connection, and in-band via a Telnet connection. In-band remote
management is possible through any SNMP compliant Network
Manage me n t Softw are.

1.1.5 Switching Options

The DLE2X-MA and DLE3X-MA provide 802.1D switc hing an d 802.1Q
switching between all of the fr ont pane l interfaces including Fast Ethernet
Interface Modules and High Speed Interface Modules (HSIMs).

The 802.1Q switching option allows for future migration to Virtual
Network technologies without requiring the replacement of existing
equipment.

1.1.6 Standards Compatibility

The DLE2X-MA and DLE3X-MA are fully compliant with the IEEE

802.3 standard. The optional Fast Ethernet Interface Modules are fully

compliant with the IEEE 802.3u standard. The DLE2X-MA and
DLE3X-MA provide IEEE 802.1D Spanning T ree Algorithm (STA)
support to enhance the ov e rall reliability of the networ k and protect
against “loop” conditions. The DLE2X-MA and DLE3X-MA support 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 the Enterprise MIBs provide a wide array of statistical
information to enhance troubleshooting.

1.1.8 Year 2000 Compliant

The DLE2X-MA and DLE3X-MA have an internal clock that can
maintain the current time and date beyond the year 1999.

1.1.9 Runtime IP Address Discovery

This feature enables the modules to aut omatic ally accept an IP address
from a BootP server on the network into NVRAM without requiring a
user to enter an IP address through Local Management.

When the modules are connected to the network and powered up,
Runtime IP Address Discov ery (RAD) checks the modules for an IP
address. If one has not yet been assigned (module and DLM6C-AA
chassis IP address set to 0.0.0.0), RAD checks to see if a ny of the module
interfaces have a link. If so, RAD sends out Reverse Address Resolution
Protocol (RARP) and BootP requests to obtain an IP address from a
RARP or BootP server on the network.

The RAD requests start out at an interval of one second. The interval then
doubles after e very 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 RARP or BootP
server, or an IP address is entered 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
High Speed Interface Module (HSIM) and the DLM6C-AA chassis. It
also allows the following tasks to be performed:

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 network port (see
Figure 3-7). Cabletron Systems supplies 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 different type on the other, such as ST
connectors, ensure that the proper crossing over occurs.

Fiber Optic Network Connection

1. Remove the protective plastic covers from the fiber optic ports on the

applicable port on the module and from the ends of the connectors.

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 connector 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, attach 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 chassis 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 subne t mask “masks out” the
network bits of the IP address by setting t he bits in t he mask to 1 whe n the
network treats the corresponding bits in the IP address as part of the
network or subnetwork add ress, or to 0 if the corresponding bit identifies
the host. The DLM6C-AA chassis automatically use s the default subnet
mask that corresponds to the IP class that wa s ent ered in the IP address
field. Section 5.7.2, Setting the Subnet Mask describes how to change the
subnet mask from the default v a lue.

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 suppor t the Port Redirect Function. Refer to
Section 5.7.7,
on configuring the operational mode of all the 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 installed, as a source or destination port. A port
can be set to have one or more desti nat ion ports and chassis module slot
numbers. For example, port 1 in module (slot) 1 can be set as a source
port with three destinati ons, ports 2, 3, and 4 in module (slot) 3. Tr affic
from port 1 in module 1 i s then automatically redirected to ports 2, 3, and
4 in module 3. Port 1 in module 1 can also serve as a destination port for
other ports an d modules. The por t re direct function is e xtr emely us eful for
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
traff ic from the source port(s) can be examined.

, for instructions

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.
