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 chec ks or adj ustmen ts. The out put 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 S tandardiz ation).
When operat ing within their per formance limitations , l as er transceiver out put meets the Cla s s 1

accessible emissio n limit of all thr ee s tandards. Class 1 lev e ls of laser radiation are not considered
hazardous.

SAFETY INFORMATION

LASER RADIATION AND CONNECTORS

When the connector is in place, all laser radiation remains within the fiber. The maximum amount of
radiant power e xiting the fiber (under norm al conditions ) is -12.6 dBm or 55 x 10

Removing the optica l connector from the transc eiver al lows laser radiation to emit dir ectly from the
optical port. The maximum radiance from the optical port (under worst case conditions) is

0.8 W cm

Do not use optical instrumen t s to view the laser output. The use of optical instruments to view
laser output increase s e ye hazard. When vi ew ing the output optical port, power must be
removed from the network adapter.

CHAPTER 1

INTRODUCTION

1.1 DLEHF-MA OVERVIEW

The DLEHF-MA, shown in Figure 1-1, is an interface module for
DIGITAL DLM6C-AA MultiSwitch 700 chassis.

The DLEHF-MA is a high-speed network switch device that supports
IEEE 802.1D switching (bridging) and IEEE 802.1Q switching. Ports 1
and 2 of the DLEHF-MA support optional Fast Ethe rn et Interface
Modules and can provide upli nks to 100BASE-TX or 100BASE-FX Fast
Ethernet networks. The DLEHF-MA is capable of being equipped with
two High Speed Interface Modules (HSIMs) that provide for additional
connectivity to other high speed netwo rking technologies such as

DLEHF-MA Overview

1.1.1 Connectivity

The DLEHF-MA has two front panel slots (ports 1 and 2) 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 DLEHF-MA also has two front panel slots for optional High Speed
Interface Modules to provide for additional connectivity to other high
speed networking technologies such as ATM, WANs and FDDI.

1.1.2 Full Duplex Switched Ethernet

The optional Fast Ethernet Interface Modules can be configured to
operate in Full Duplex Swi tched Ethernet mode, which provides
200 Mbps of throughput per interface.

1.1.3 A uto -N eg ot iation

The optional DELTX-UI Fast Ethernet Interface Module can
auto-negot iate the type of connectio n require d to provi de a link to another
device. Duri ng Auto-Negotiation, two devic es automatically exch ange
information “telling” each other what their ope rating capabilities ar e. The
Auto-Negotiation feature targets the maximum capabilities that can be
reached between the two devices. For example, a DLEHF-MA
DEL TX-UI Fast Ethernet Interface Module adjusts to 100 M bps when the
device on the othe r end of the connection can also adjust between 10 or
100 Mbps. If the device on the other end of the connection can only
operate at 10 Mbps, then the DLEHF-MA DELTX-UI Fast Ethernet
Interface Module simply 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 duple x operation based on the
maximum capability that can be reac hed between the two device s. I f the
device connected to the DLEHF-MA cannot auto-neg otiate, the
DLEHF-MA Fast Ethernet Interface Module operates according to the
capabilities of the other device.

1.1.4 Managem ent

Management of the DLEHF-MA is accomplished using Local
Management tools or remote SNMP management stations.

DLEHF-MA User’s Guide 1-3

Chapter 1: Introduction

Local Management is accessible through the RS232 COM port on the
front panel using a local VT100 termina l, or a remote VT100 termin al via
a modem connection, and in-band via a Telnet connection. In-band
remote management is possible through any SNMP compliant Network
Management Soft ware.

1.1.5 Switching Options

The DLEHF-MA provides IEEE 802.1D switching or IEEE 802.1Q
switching between the two Fast Ethernet Interface Modules and High
Speed In te rface Modules (HSIMs).

HE 802.1Q switching option allo ws for migration to Virtual Network

T
technologies without requiring the replace ment of existing equipment.

1.1.6 Standards Compatibility

The DLEHF-MA is fully compliant with the IEEE 802.3 standard. The
optional Fast Ethernet Interface Modules are fully compliant with the
IEEE 802.3u standard. The DLEHF-MA provide s IEEE 802.1D Spanning
Tree Algorithm (STA) support to enhance the overall reliabilit y of the
network and protect ag ainst “loop” conditions. It also supports a wide
variet y of industry standard MIBs including RFC 1213 (MIB II),
RFC 1271 (RMON), RFC 1317 (RS232 MIB), RFC 1493 (Bridge MIB),
RFC 1354 (FIB MIB) , a nd RFC 1573 (Evolution of MIB II Interfaces). A
full suite of Cabletron Enterprise MIBs provide a wide array of statistical
information to enhance troubleshooting.

1.1.7 Year 2000 Compliance

The DLEHF-MA has an internal clock that can maintain the cur rent time
and date beyond the year 1999.

Local Management Features

1.1.8 LANVIEW Diagnostic LEDs

LANVIEW diagnostic LEDs serve as a n importa nt t roubleshoot ing aid by
providing an e asy w ay to obse rv e the s tatus of i ndi vi dual ports a nd o ve rall
network operations. Chapter 4 provides deta ils about the DLEHF-MA
LANVIEW LEDs.

1.1.9 Runtime IP Address Discovery

This feature enables the DLEHF-MA to automatically accept an IP
address from a BootP server on the network into NVRAM without
requiring the user to enter an IP address through Local Management.

When the DLEHF-MA is connected to the network and po wered up,
Runtime IP Address Discovery (RAD) checks the DLEHF-MA for an IP
address. If one has not y et been assigned, RAD checks to see if any of the
DLEHF-MA interfaces has a link. If so, RAD sends out Reverse Address
Resolution Protocol (RARP) and BootP requests to obtain an IP address
from a BootP or RARP server on the network.

The RAD requests start out at an interval of 1 second and double 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 or RARP server, or an IP
address is entered usin g Local Management.

1.2 LOCAL MANAGEMENT FEATURES

Local Management provides the tools that allow management of the
DLEHF-MA, the Fast Etherne t Int erface Modules, all HSIMs, and the
DLM6C-AA chassis. Local Management for the DLEHF-MA pro vides
the features detaile d in Sections 1.4.1 through 1.4.6.

1.2.1 Distributed Chassis Management

From a management perspective, the DLM6C-AA MultiSwitch 700
chassis can be viewe d as a single entity with a single IP address. Its
management functions are distr ibuted t o a ll modules. This means a single
module in the chassis, such as the DLEHF-MA, can be used to manage
the entire chassis, and any other attached module through Local
Management, SNMP, or Telnet applic at ions.

DLEHF-MA User’s Guide 1-5

Chapter 1: Introduction

1.2.2 Remote Monitoring (RMON)

The DLEHF-MA supports all Ethernet RMON groups, which incl ude
Statistics, Alarm s, Events and History. These groups are enabled on all
ports by default.

DIGITAL 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 an y RMON Eve nt and/or Alarm. An example
of an Action would be to turn off a MIB-2 interface if a broad ca st
threshold is crossed.

1.2.3 Broadcast Suppression

Broadcast Suppression a llows a user to set a desired limit of receive
broadcast frames per port/per second to be forwarde d out 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, multic ast and unicast frames contin ue to be switc hed.

1.2.4 Port Redirect Function

The port redirect funct ion, also referred to as “Port Mirroring,” is a
troubleshooting tool used to map traffic from a single source port or
multiple source ports to a destination port(s) within the chassis. This
feature functi ons at the bit level, which allows all pac kets, includi ng those
with errors, to be copied and sent to an analyzer or RMON probe. The
analyzer or RMON probe will see the data as if it is dir ectly connected to
the LAN segment of the source port( s).

1.2.5 SmartTrunk

The SmartTrunk f eature allows the user to set a group of DLEHF-MA
interfaces, so they can share the traffic load and effectively increase the
bandwidth between connect ed DLEHF-MAs or other DIGITAL devices
supporting the SmartTrunk feature.

1-6 DLEHF-MA User’s Guide

Optional Features

For example, the two Fast Etherne t Interface Modules could be groupe d to
provide a 200 Mbps uplink in standard operation and a 400 Mbps uplink
if set to operate in full duplex mode.

1.2.6 Additional Local Management Functions

Local Management also allows the follo wing tasks to be performed:

• Manage any module installe d in the DLM6C-AA via a single terminal

connection.

• Assign an IP addr ess and su bnet m ask to th e DLEHF-MA mod ule and

DLM6C-AA chassis.

• Select a default gateway.

• Control local and remote access.

• Designate workstations to receive SNMP traps from the DLEHF-MA

module and DLM6C-AA chassis.

• Configure module specific SNMP MIB objects including the IETF

Bridge MIB objects.

Chapter 5 provides det ailed information about Local Mana gement of the
DLEHF-MA, the optional Fast Ethernet Interface Modules and the
DLM6C-AA chassis. The a ssoc iated High Spee d I nterface Module user’s
guide provides detailed information about Local Management of the
applicable HSIM.

1.3 OPTIONAL FEATURES

Options for the DLEHF-MA are Fast Ethernet Interface Modules and
High Speed Interface Modules to add uplink capability.

DIGITAL provides Fast Ethernet I nterface Modules for the DLEHF-MA

Connecting to the Network

3.5.2 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 3-3).

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 rubber covers from the fiber optic ports 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

!

!

instrume nts to view the laser output. The use of optical
instrume nts 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, blow the
surfaces with a canned duster. A fiber port cleaning swab
saturated with optical-grade isopropyl alcohol may also be used
to clean the ends.

2. Insert one end of the SC connector into the DELFX-UI or the

DELF3-UI installed in the DLEHF-MA. See Figure 3-3.

5.4.1 Navigating Local Management Screens

The DLEHF-MA Local Management application consists of a series of menu
screens. Navigat e through Lo cal Management by sel ecting items from the
menu screens.

The DLEHF-MA support s three mode s of switc h operati on. The swi tching
modes are as follo ws:

• 802.1D SWITCHING (IEEE 802.1D switching)

• 802.1Q SWITCHING (802.1Q port based VLANs)

Refer to the Release Notes shipped with the product to verify
which screens are suppor ted in each of the two available
switching modes.

The switch operation al mode may be set in eithe r the Chassis Con figuration
screen (Section 5.7), or the Genera l Configuration screen of the module
(Section 5.15). Depending on the Operational Mode set for the module,
the hierarchy of Local Management screens differs as shown in
Figure 5-4 and Figure 5-5. Refer to the appropriate figure that relates to
the Operational Mode that will be set for the module to see the applicable

802.1D SWITCHING. Refer to the Release Notes to verify
which operational modes support the Por t Redirect Function
screen.

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
(interfa ces ) of the co rre sponding module installed, as a source or
destination port. A port can be set to have one or more destination port
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 automatically
redirected to ports 2, 3, and 4 in module 3. Port 1 in module 1 can also
serve as a destinat ion port for other ports and modules. The port redirect
function is extremely useful 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 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.

To access the Port Redir ect Function screen from the Chassis Menu
screen, use the arrow keys to highlight the PORT REDIRECT menu
item and press ENTER. The Port Redirect Function screen , Fig ur e 5-13,
displays.
