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 Electro technical Standard ization). When operating within their performance limitations, laser transceiver output meets the Class 1

accessible emission limit of all three standar ds. Class 1 levels of laser radiation are not considered hazardous.

SAFETY INFORMATION

CLASS 1 LASER TRANSCEIVERS

LASER RADIATION AND CONNECTORS

When the connect or is in place, all laser radiation remains within the fiber. The maximum amount of radiant power exiting the fibe r (under norm al conditions) 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 vie w th e laser output. The use of opt ical inst ruments to view laser output increases eye hazard. When vi ew ing the output optical port, power must be removed from the network adapter.

DLE28-MA Overview

1.1.1 Connectivity

The DLE28-MA connects to Ethernet networks or workstations through 24 ST fiber optic ports on the front panel. These ports support multimode fiber optic cables at lengths up to 2 kilometers. The ports are IEEE 802. 3 10BASE-F compliant.

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 20 Mbps of bandwidth.

The optional Fast Ethernet Interface Modules for the DLE28-MA can also be configured to operate in Full Duplex Switched Ethernet mode, which provides 200 Mbps of bandwidth.

1.1.3 Management

Management of the DLE28-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 Management Software.

1.1.4 Switching Options

The DLE28-MA provides 802.1D switching (bridging) and 802.1Q switching between all of the front panel interfaces including Fast Ethernet Interface Modules and High Speed Interface Modules (HSIMs).

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

1.1.5 Standards Compatibility

The DLE28-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 DLE28-MA provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The DLE28-MA supports

DLE28-MA User’s Guide 1-3

Chapter 1: Introduction

a wide variet y 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 DIGITAL Enterprise MIBs provide a wide array of statistical information to enhance trou ble shooting.

1.1.6 LANVIEW Diagnostic LEDs

LANVIEW diagnostic LEDs serve as a n importa nt t roubleshoot ing aid b y providing an easy w ay to obse rv e the s tatus of ind i vi dual ports a nd o ve rall network operations. Chapter 4 provides details about the DLE28-MA LANVIEW LEDs.

1.1.7 Year 2000 Compliant

The DLE28-MA has an internal clock that can maint ain the current time and date beyond the ye ar 1999.

1.1.8 Runtime IP Address Discovery

This feature enables the modules to automatically accept an IP address from a BootP server on the networ k into NVRAM without requiring a user to enter an IP address through Local Mana geme nt.

When the modules are connected to the netw ork and powered up, Runtime IP Address Discovery (RAD) checks the module s 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 see 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 BootP or RARP 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 interva l 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 using Local Management.

Local Management Features

1.2 LOCAL MANAGEMENT FEATURES

Local Management pr ovides the tools that allow management of the DLE28-MA, the Fast Ether net Interface Modules, all HSIMs, and the DLM6C-AA chassis. Local Management f or the DLE28-MA provide s the features detailed in Sections 1.4.1 through 1.4.6.

1.2.1 Distributed Chassis Management

From a management perspe ctive, the DLM6C-AA DIGITAL MultiSwitch 700 chassis can be viewe d as a single entity with a single IP address. Its management functions are distributed to all modules. This means a single module in the chassis , such as the DLE28-MA, can be used to m anage the entire chassis, and any other attached modul e through Local Management, SNMP, or Telnet applications.

1.2.2 Remote Monito ring (RMON)

The DLE28-MA supports all Ethe rnet RMON groups, whic h include Statistics, Alarm s, Events and Histor y. These groups are enable d on all ports by default.

DIGITAL RMON Actions is a vendor spe cific extension of RMON and provides the ability to set an “Action” on any SNMP MIB variable. The Action can be triggered by a ny RMON Event and/or Alarm. An example of an Action would be to turn off a MIB-2 interface if a broadcast 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 forwar ded 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 broadc ast frames are being suppressed, multic ast and unicast frames contin ue to be switc hed.

MAC Address

(Read-Only)

Displays the ba se physical address of the chassis.

5-16 DLE28-MA User’s Guide

Chassis Configuration Screen

IP Address (Modifiable)

This field allows the IP address to be set for the DLM6C-AA chassis. If an IP addre s s is assign e d to th e DLM 6 C- A A cha s sis all the interface modules installed in the chassis can be managed via this IP address, eliminating the need to assi gn an IP address to e ach interface module. To set the IP address, refer to Section 5.7.1.

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 va lue. Refer to your Re lease Not es 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 addre ss as par t 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.

Chassis Date (Modifiable)

Contains a value that the chassis recognizes as the current date. When the chassis date is modified and saved all interface modules installed in the chassis are set to this date. To set a new chassis date, refer to Section 5.7.3.

Chassis Time (Modifiable)

Contains a value that the chassis recognizes as the current time. When the chassis time is modified and saved, all interface modules installed in the chassis are set to this time. To enter a new time, refer to Section 5.7.4.

Screen Refresh Time (Modifiable)

Contains the rate at which the scree ns are updated. This setting determines ho w frequently (in seconds) information is updated on the screen. To enter a new update time, r efer to Section 5.7.5.

5.11 PORT REDIRECT FUNCTION SCREEN

The Port Redirect Function screen may not be ava ilable depending on the operational mode that has been set for the chassis. Refer t o your Release Notes to see what operational modes support the Por t Redirect Function. 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 t o set each one of the modules in the cha ssis (1 through 5), and the ports of the corresponding module insta lled, as a source or destina tion 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 automatically 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 a llows traffic to be sent to a particula r 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.
