Introduction

How to use the EMM-E6 User’s Guide; manual conventions; contacting the Cabletron Systems Global Call Center; EMM-E6 ﬁrmware versions supported by SPMA

The EMM-E6 (Ethernet Management Module for Ethernet with six ports)

provides intelligence for Cabletron Systems’ Multi-Media Access Center (MMAC)

hubs. The EMM-E6 is designed to work with the repeater MIM family of media

interface modules (FORMIM, CXRMIM, TPRMIM, and TPXMIM) to take full

advantage of the MMAC Flexible Network Bus (FNB). The EMM-E6 uses the

dedicated Ethernet channel (channel A) on the MMAC backplane and creates two

more Ethernet channels (B and C) using the FNB, then bridges among these three

interfaces, as well as a fourth channel (D) provided by a set of redundant EPIM

ports located on its front panel. Fifth and sixth channels are provided by optional

BRIM modules, also installed on the front panel, which support cross-platform

bridging and routing. The EMM-E6 also provides management and serves as a

repeater for older MIMs that are not part of the repeater MIM family.

Although the Hub View window displays the presence and general status (on or off) of

NOTE

any installed BRIM modules, you cannot perform any management of BRIM ports from the Hub View application. The functions associated with any BRIM modules installed in your EMM-E6 can be conﬁgured and managed via the SPMA BRIM Launcher application; the BRIM Launcher is described in the SPMA BRIM User’s Guide .

Using the EMM-E6 User’s Guide

Your SPECTRUM Portable Management Application (SPMA) for the EMM-E6

consists of a number of different applications, each of which provides a portion of

the overall management functionality. Each of these applications can be accessed

from the icon menu (if you are using a management platform) and from the

1-1

Introduction

Stand-alone Launcher or the command line (if you are running in stand-alone mode); in addition, several applications can also be accessed from within the Hub View, a graphical display of the EMM-E6 and the hub it is managing.

The EMM-E6 User’s Guide describes how to use many of the applications included with the module; note that the instructions provided in this guide apply to the EMM-E6 module regardless of the operating system or management platform you are using. Instructions for launching each individual function from the command line (stand-alone mode) are also included in each chapter.

Following is a description of the applications covered in this guide; while we provide as much background information as we can, we do assume that you’re familiar with Ethernet networks and general network management concepts:

• Chapter 1, Introduction , provides a list of related documentation, describes

certain software conventions, and shows you how to contact the Cabletron

Systems Global Call Center.

• Chapter 2, Using the EMM-E6 Hub View , describes the visual display of the

Hub and explains how to use the mouse within the Hub View; the operation

of some basic functions (changing the Hub View display, opening menus and

windows, enabling and disabling ports, checking device and module status,

and so on) available only from within the Hub V iew is also described. You can

access the Hub View application from the icon menu or the command line.

• Chapter 3, Alarm Conﬁguration , describes how to set thresholds and enable

or disable alarms at the network (channel), module, and port levels. You can

access the Alarm Conﬁguration application from the icon menu, the Hub V iew ,

or the command line.

• Chapter 4, Link/Seg Traps , describes how to conﬁgure link and segmentation

traps to suit your management needs. You can access the Link/Seg Traps

application from the icon menu, the Hub View, or the command line.

• Chapter 5, Redundancy , describes how to conﬁgure redundant circuits to keep

your network connections up and running in the event of a single port’s

failure. You can access the Redundancy application from the icon menu, the

Hub View, or the command line.

• Chapter 6, Source Addressing , describes how to display the Source Address

List, how to set the ageing time, and how to conﬁgure source address traps; it

also discusses the effects of source address locking. You can access the Source

Address application from the icon menu, the Hub View, or the command line.

• Chapter 7, Security , describes how to conﬁgure intruder protection for all

MIMs installed in the EMM-E6-controlled hub, and how to conﬁgure

eavesdropper protection for any installed

LANVIEW

SECURE

MIMs. You can access the Security application from the icon menu, the Hub View, or the command line.

1-2 Using the EMM-E6 User’s Guide

• Chapter 8, Front Panel Redundancy , describes how to conﬁgure redundancy

for the two Channel D EPIM ports on the EMM-E6’s front panel. You can access the Front Panel Redundancy application from the icon menu, the Hub View, or the command line.

• Appendix A, EMM-E6 MIB Components , lists the IETF MIBs supported by

the EMM-E6, and describes their arrangement in a series of MIB components. A description of the objects controlled by each component is also included.

What’s NOT in the EMM-E6 User’s Guide. . .

The following standard SPMA tools are available through the EMM-E6 module and are explained in the SPECTRUM Portable Management Application Tools

Guide :

• Bridge View

Introduction

• Charts, Graphs, and Meters

• Community Names

• Distributed LAN Monitor (DLM)

• MIB I, II

• MIBTree

• Path

• Telnet

• TFTP Download

• Trap Table

• UPS

• Utilities (Global Community Names, Find MAC Address and TFTP) Charts, Graphs, and Meters are accessible from the Hub View and the command

line; the Utilities, MIBTree, and RMON Conﬁguration applications are accessible from the platform console window Tools menu, the Stand-alone Launcher applications menu, or the command line; and the rest of the tool applications (except Telnet) are available from the icon menu, the Hub View, or the command line. (The T elnet application is available only fr om the icon menu or the command line.)

An additional application may also appear on the platform console window T ools menu or the Stand-alone Launcher applications menu:

• RMON Conﬁguration Note that this application must be purchased separately, and is documented in its

own User’s Guide .

Using the EMM-E6 User’s Guide 1-3

Introduction

NOTE

If you are using SPMA in a stand-alone mode or in conjunction with the SunNet Manager or Solstice Enterprise Manager platforms, the RMON option will be available for all appropriate devices whether or not you have purchased the RMON application module. If you are using SPMA in conjunction with HP Network Node Manager or IBM NetView, however, the RMON option will only appear when the module has been purchased and installed.

Instructions on discovering Cabletron devices, creating icons, and accessing the icon menus within your management platform are included in your Installing

and Using SPECTRUM for... guide. If you are using SPMA for the EMM-E6 in

stand-alone mode — that is, without beneﬁt of a speciﬁc network management system — instructions for starting each application from the command line are included in each chapter of this guide and the

SPMA Tools Guide .

NOTE

Graphing capabilities are provided by an application that is included in HP Network Node Manager and IBM NetView; therefore, graphs are only available when SPMA is run in conjunction with one of these network management platforms. If you are running SPMA in a stand-alone mode or in conjunction with SunNet Manager or Solstice Enterprise Manager, no graphing capabilities are available and no graph-related options will be displayed on buttons or menus. Note that the screens displayed in this guide will include the graph-related options where they are available; please disregard these references if they do not apply.

Also available from the icon menu or the command line is the option which provides access to BRIM-related applications and two options which provide access to router-related applications: the BRIM option is described in the SPMA

BRIM Applications User’s Guide ; the Basic Router Conﬁg , and Advanced

Router Conﬁg , options are described in documentation shipped with your order

of routing applications, which must be purchased separately.

Please note that the routing functionality for your EMM-E6, as well as the SPMA management modules that allow you to conﬁgure and manage that functionality, must be purchased separately. Contact the Cabletron Systems Global Call Center or your local sales representative for more information.

Conventions

SPECTRUM Portable Management Applications — including the EMM-E6 module — can work with a number of different network management systems running on several different operating systems and graphical user interfaces. This versatility presents two documentation problems: ﬁrst, there is no standard terminology; and second, the appearance of the windows will differ based on the

1-4 Conventions

graphical interface in use. For the sake of consistency, the following conventions will be followed throughout this and other SPMA guides.

Screen Displays

SPMA runs under a variety of different operating systems and graphical user interfaces. To maintain a consistent presentation, screen displays in this and other SPMA guides show an OSF/Motif envir onment. If you’r e used to a dif fer ent GUI, don’t worry; the differences are minor. Buttons, boxes, borders, and menus displayed on your screen may look a bit different fr om what you see in the guide, but they’re organized and labelled the same, located in the same places, and perform the same functions in all screen environments.

Some windows within SPMA applications can be re-sized; those windows will display the standard window resizing handles employed by your windowing system. Re-sizing a window doesn’t re-size the information in the window; it just changes the amount of information that can be displayed (see Figure 1-1). When you shrink a window, scroll bars will appear as necessary so that you can scroll to view all the information that is available.

Introduction

Use the scroll bars provided to choose what to display in a window that’s been resized

Click here to display footer message history

Figure 1-1. Window Conventions

Conventions 1-5

Introduction

Some windows will also contain a button; selecting this button launches a History window (Figure 1-2) which lists all footer messages that have been displayed since the window was ﬁrst invoked. This window can help you keep track of management actions you have taken since launching a management application.

Using the Mouse

The UNIX mouse has three buttons. Procedures within the SPMA document set refer to these buttons as follows:

Figure 1-2. The History Window

Button 1

Button 2

Button 3

Figure 1-3. Mouse Buttons

1-6 Conventions

Introduction

If you’re using a two-button mouse, don’t worry. SPMA doesn’t make use of mouse button 2. Just click the left button for button 1 and the right mouse button when instructed to use mouse button 3.

Whenever possible, we will instruct you on which mouse button to employ; however, menu buttons within SPMA applications will operate according to the convention employed by the active windowing system. By convention, menu buttons under the Motif windowing environment are activated by clicking the left mouse button (referred to as mouse button 1 in SPMA documentation), and there is no response to clicking the right button (mouse button 3). Under OpenWindows, menu buttons can be activated by clicking the right button, and convention dictates that the left button activates a default menu option; within SPMA, that default option will also display the entire menu. Because of this difference, references to activating a menu button will not include instructions about which mouse button to use. All other panels from which menus can be accessed, and all buttons which do not provide access to menus, will operate according to SPMA convention, as documented.

EMM-E6 Firmware

SPMA for the EMM-E6 has been tested against ﬁrmware versions 3.22.01; if you have an earlier version of ﬁrmware and experience problems running SPMA contact the Cabletron Systems Global Call Center for upgrade information.

As a general rule, ﬁrmware versions for new products are liable to change rapidly; contact

NOTE

the Cabletron Systems Global Call Center for upgrade information for the latest customer release of ﬁrmware.

Introduction

Year 2000 Compliance

Previous users of SPMA will note a few display changes related to Year 2000 compliance. All SPMA applications now have the ability to display a four-digit year value where this information is available. For example, the Stand-alone Launcher window — which uses your workstation’s system time value to display the time and date of the last contact change — will now display these date values with eight digits (05/31/1998) instead of six (05/31/98).

Please keep in mind, however, that SPMA’s ability to display a four-digit year value in device-speciﬁc windows — such as the Device Status window available from the Hub View or the Bridge View — is dependent on the ﬁrmware’s ability to provide a four -digit value. Not all ﬁrmware versions support this ability; contact Cabletron Systems’ Global Call Center for information speciﬁc to your device ﬁrmware.

EMM-E6 Firmware 1-8

Using the EMM-E6 Hub View

Navigating through the Hub View; monitoring hub performance; managing the hub

The heart of the SPECTRUM Portable Management Application (SPMA) for the EMM-E6 is the Hub View, a graphical interface that gives you access to many of the functions that provide control over the EMM-E6-managed hub.

Using the Hub View

There are two ways to open the Hub View: if you are working within a network management system, you can select the Hub View option from the icon menu; speciﬁc directions for creating a EMM-E6 icon and accessing the icon menu can be found in the appropriate Installing and Using SPECTRUM for ... guide. If you are running the EMM-E6 module in a stand-alone mode, type the following at the command line:

Chapter 2

NOTES

spmarun emme <IP address> <community name>

The community name you use to start the module must have at least Read access; for full management functionality, you should use a community name that provides Read/Write or Superuser access. For more information on community names, consult the appropriate Installing and Using SPECTRUM for... guide, and/or the Community Names chapter in the SPMA Tools Guide.

The spmarun script invoked ﬁrst in the above command temporarily sets the environment variables SPMA needs to operate; be sure to use this command any time you launch an application from the command line. This script is automatically invoked when you launch an application from the icon menu or from within the Hub View.

If there is a hostname mapped to your EMM-E6’s IP address, you can use <hostname> in place of <IP addr ess> to launch the Hub View . Please note, however, that the hostname is not the same as the device name which can be assigned via Local Management and/or SPMA; you cannot use the device name in place of the IP address.

2-1

Using the EMM-E6 Hub View

Navigating Through the Hub View

Within the Hub View, you can click mouse buttons in different areas of the window to access various menus and initiate certain management tasks. The following diagrams describe the information displayed in the Hub View and show you how to use the mouse to display the Device, Network, Module, and Port menus.

No Mgmt

Depending on the version of ﬁrmware installed in your EMM-E6, certain MIMs either may not display at all, or may display with the message “No Mgt” in the Port Display Form box. For more information about the speciﬁc capabilities of different versions of EMM-E6 ﬁrmware, contact the Cabletron Systems Global Call Center.

Using the EMM-E6 Hub View

Contact Status is a color code that shows the status of the connection between SPMA and the device:

• Green means a valid connection.

• Blue means that SPMA is trying to reach the device but doesn’t yet know if the

connection will be successful.

• Red means that SPMA is unable to contact or has lost contact with the device.

Uptime

The time that the device has been running without interruption. The counter resets to 0 days 00:00:00 (days HH:MM:SS) when one of the following occurs:

• Power to the device is cycled.

• The device is reset manually.

Date and Time

The date and time are taken from the device’s internal clock.

Device Name

A text ﬁeld that you can use to help identify the device; you can edit the device name via the Device Status window, described on page 2-13.

Device Location

A text ﬁeld that you can use to help identify the device; you can edit the device location via the Device Status window, described on page 2-13.

IP Address

The device’s Internet Protocol address; this ﬁeld will display the IP address you have used to create the EMM-E6 icon (if you are running the Hub View from a management platform) or the IP address you used to launch the Hub View program (if you are running in stand-alone mode). You cannot change the EMM-E6’s IP address from SPMA; however, you can view the MAC addresses of all installed interfaces (up to six), along with any associated IP addresses that have been assigned, by using the IP Address Table function described on

page 2-19.

MAC Address

The device’s factory-set hardware address; this ﬁeld will display the MAC address associated with the IP address used to deﬁne the icon (if you are running the Hub View fr om a management platform) or the IP addr ess you used to launch the Hub View program (if you are running in stand-alone mode). The MAC addresses cannot be changed.

Figure 2-3. Hub Information Window

Clicking mouse button 1 on the Quit button closes all Hub View application windows; any open applications which can also be accessed from the command line or from the icon menu will remain open.

EMM-E6 Ports Display

The EMM-E6 module display in the Hub View shows the device’s ﬁrst four channels in two different modes: their Bridge Port Status (ON or OFF), and their Bridge Port State (Listening, Learning, Forwarding, Blocking, or Disabled). Status displays are color coded green for ON, blue for OFF; state displays are color coded yellow for Listening and Learning, green for Forwarding, red for Blocking, and blue for Disabled. The current redundancy status (Active or Inactive) of the Channel D EPIM ports is also displayed. BRIM ports E and F will display status colors (green for ON, blue for OFF) for any installed BRIM modules, along with the BRIM type (FDDI, WAN, TR, ATM, or ENET).

Although the Hub View displays the presence and general status (ON or OFF) of any

NOTE

installed BRIM modules, you cannot enable or disable these ports from the Hub View. To manage any installed BRIMs, launch the Bridge application from the Device menu, or launch any other application available for your BRIM from the BRIM Launcher application; see Chapter 1 for more information on how to access BRIM-speciﬁc management.

Hub View Port Color Codes

The Port Status boxes in the Hub View are color coded to indicate the port’s connection status. The colors are consistent for all Port Display Forms except Admin Status and FNB Channel; the exceptions are noted below.

Using the Hub View 2-7

Using the EMM-E6 Hub View

• Green indicates that the port is active; that is, the port has been enabled by

management, has a valid Link signal (if applicable), and is able to communicate with the station at the other end of the port’s cable segment. Note that an AUI or transceiver port will display as active as long as it has been enabled by management, even if no cable is connected.

• Blue indicates that the port has been disabled through management.

• Yellow indicates that the port is enabled but does not currently have a valid

connection. This usually indicates that the device at the other end of the segment is turned off, or that there is no cable attached.

• Red indicates that the port is enabled, but is not able to pass packets. This

generally means that the port has been segmented by management after experiencing an excessive number of collisions; for a BNC (thin coax) port, however, this may only mean that no cable or terminator has been connected.

• Magenta indicates that the EMM-E6 can’t manage the device. When the Admin Status port display option is active, only two colors apply: a

port will be displayed in green if it is enabled by management, regardless of whether or not there is a cable attached or a valid link signal detected; a port disabled by management will display as blue.

When the FNB Channel option is active, an entirely different color scheme is employed: salmon = Channel A; light blue = Channel B; orange = Channel C, and grey = stand-alone.

Monitoring Hub Performance

The information displayed in the Hub View can give you a quick summary of device activity, status, and conﬁguration. SPMA can also provide further details about hub performance via its four-level menu structure. The Device, Network, Module, and Port menus (Figure 2-6, below) give you control over the hub at four levels and give you access to the tools, menus, and windows that let you monitor speciﬁc aspects of hub performance, change hub display options, and set EMM-E6 operating and notiﬁcation parameters. Remember, though many functions will operate the same at each level, those accessed via the Device menu control or provide information about all modules in the hub; those accessed via the Network menu control or provide information about all modules in a particular network, or channel; those accessed via the Module menu control or provide information about a single module; and those accessed via the Port menu control or provide information about a single port.

2-8 Monitoring Hub Performance

Using the EMM-E6 Hub View

Figure 2-6. The EMM-E6’s Device, Network, Module, and Port Menus

Hub performance data available through these menus includes:

• Device, Network, Module, and Port status descriptions.

• Network, Module, and Port statistics, which provide a complete br eakdown of

packet activity.

• Network-, Module-, and Port-level pie charts, graphs, and meters, for a

graphic representation of the types and levels of trafﬁc passing through the hub. (For more information about pie charts, graphs, and meters, see the Charts, Graphs, and Meters chapter in the SPMA Tools Guide.)

Graphing capabilities are provided by an application that is included in HP Network

NOTE

Node Manager and IBM NetView; therefore, graphs are only available when SPMA is run in conjunction with one of these network management platforms. If you are running SPMA in a stand-alone mode or in conjunction with SunNet Manager or Solstice Enterprise Manager, no graphing capabilities are available and no graph-related options will be displayed on buttons or menus. Note that the screens displayed in this guide will include the graph-related options where they are available; please disregard these references if they do not apply.

Port Display Form

You can change the type of information displayed for each port in the hub by using the Port Display Form option on the Device, Network, and Module menus.

Monitoring Hub Performance 2-9

Using the EMM-E6 Hub View

Changing the port display form via the Device menu will affect all manageable ports in the hub; using the Network menu will affect all ports on a speciﬁc channel, or network; and using the Module menu will affect all ports on the appropriate module.

If there is a TPXMIM in multi-channel mode installed in your EMM-E6-managed hub,

NOTE

the Port Display Form option will not be available from that MIM’s Network menu; in addition, a TPXMIM in multi-channel mode will not respond to changes in Port Display Form made via any other MIM’s Network menu. However, the TPXMIM will always respond to changes in port display form initiated via the Module or Device menus.

For more information about the TPXMIM and its multi-channel capabilities, see

Conﬁguring TPXMIM Connections, page 2-30.

To change the port display form:

1. Click in the appropriate area to display the Device, Network, or Module menu (refer to Figure 2-5, page 2-7).

2. Drag down to Port Display Form , then right as necessary to select one of the port display options. The current selection will be displa y ed in the Port Display Form text box(es) on the module displays.

Port display form options are:

Load

Shows a percentage for each active port that represents that port’s portion of the theoretical maximum trafﬁc level — for Ethernet networks, 10 megabits per second.

Trafﬁc

Displays port trafﬁc data in a packets/second format.

Collisions

Displays port trafﬁc data in a collisions/second format. The EMM-E6 counts both receive collisions — those collisions it detects while receiving a transmission — and transmit collisions —those it detects while transmitting (i.e., the EMM-E6 transmitted one of the colliding packets); however, those counts are combined and a single total value is displayed.

Errors

Shows port trafﬁc errors in an errors/second format. You can display any one of the following types of errors:

• Total errors

• Alignment errors

• CRC (Cyclic Redundancy Check) errors

• Runts

• Giants

2-10 Monitoring Hub Performance

Using the EMM-E6 Hub View

• OOW (Out-of-Window) Collisions For error type descriptions, see Checking Statistics on page 2-20.

Protocols

Displays a percentage for each active port that represents what portion of that port’s trafﬁc is of a particular protocol type. You can display any one of the following protocol types:

•IP

• OSI

• XNS

• DECNet

• Novell

• Appletalk

• Banyan

• Cabletron

• Other

Frame Sizes

Displays a percentage for each active port that represents what portion of that port’s trafﬁc is of a speciﬁc size, measured in bytes. You can display any one of the following frame sizes:

NOTE

• Runts (packets with fewer than 64 bytes)

• 64-127

• 128-255

• 256-511

• 512-1023

• 1024-1518

• Giants (packets with more than 1518 bytes)

For the statistical port display form options listed above, three dashes (---) will display for all inactive ports; any active (green) port will display a numeric value, even if it’ s 0.0000.

Port T ype

Provides the following administrative information about the port:

• Admin/Link Status indicates the connection status of the port:

- ON indicates that the port has a valid link signal or does not support a link

signal.

- OFF indicates that the port has been turned off through management

action.

- NLK (No Link) indicates that the port does not have a link to a device at

the other end of the cable, or that there is no cable attached.

Monitoring Hub Performance 2-11

Using the EMM-E6 Hub View

- SEG (Segmented) indicates that the port has been segmented by the

Because BNC thin coax, AUI, and transceiver ports do not support the link feature, the

NOTE

displayed Admin/Link status for those ports may be misleading: for example, a BNC port will display as segmented when, in fact, there is no cable or terminator attached or the cable has been disconnected; and AUI or transceiver port will display as on (with a valid link signal) even when no cable is attached. Be sure to keep these anomalies in mind when troubleshooting a hub so equipped.

• Admin Status displays either ON or OFF, an indication of whether management has the port enabled or disabled. A port can be ON but not operational; for example, under the Admin display, ports that are segmented or not linked are shown as ON.

• Active Ports displays either YES or NO for any active (gr een) port, indicating whether or not that port has seen any trafﬁc at all since the device was last initialized; this port display form can tell you whether any port whose statistics are not currently incrementing has seen some activity in the past. Non-green (presumably inactive) ports will display three dashes (---), regardless of their past statistical activity.

repeater due to an excessive collision level.

NOTE

• Topology displays either TRUNK or STN (station), a status which is deﬁned by how many source addresses are communicating through that port at any given moment: if zero, one, or two addresses are communicating, the port is considered to be a station port; if more than two addresses ar e communicating, the port is considered to be a trunk port. See Setting a Port’s Trunk Type,

page 2-32, for more information.

If you use the Trunk Type option on the Port menu to manually change a port’s topology status from Force Trunk to Not Forced, any status change from trunk to station will not be reﬂected in the port display until the current cycle of the Source Address timer is complete. See Chapter 6, Source Addressing, for more information on the timer.

Older versions of EMM-E6 ﬁrmware (previous to revision level 2.00.16) use slightly different deﬁnitions of station and trunk status: station ports are deﬁned as those which are detecting no source addresses or only a single source address; trunk ports are those detecting two or more. If you have any questions about which deﬁnition your version of ﬁrmware employs, or if you would like information about upgrading your EMM-E6 ﬁrmware, contact the Cabletron Systems Global Call Center. Also, see Chapter 6, Source Addressing, and Chapter 7, Security, for more information about station and trunk status.

• FNB Channel displays a letter which indicates each port’s current channel assignment: A, B, C, or SA (stand-alone).

Monitoring Hub Performance 2-13

Using the EMM-E6 Hub View

If your device ﬁrmware can accept four-digit year values, the Date ﬁeld will allow you to

NOTE

enter the year portion in one-, two-, or four-digit format. If you choose to enter one or two digits for the year, any value greater than or equal to 88 will be presumed to be in the 1900s; a value of 87 or less is presumed to be in the 2000s. No matter which entry format you choose, the year will still be displayed and set as a four-digit value.

If your device ﬁrmware cannot accept four-digit year values, the Date ﬁeld will allow you to enter the year portion in one- or two-digit format (with leading zeros supplied automatically for single-digit entries). No presumption is made about the century, and any two-digit year value (from 00 to 99) will be accepted.

Attempts to set the date may result in one of three different error messages. Two of these messages will indicate that the wrong number of digits has been used for the year value, and will indicate the appropriate number of digits to use for the selected device; the third message will indicate that the entered date is invalid because it is not an actual calendar date (such as 02/29 in a non-leap year , any month value gr eater than 12, or any day value greater than 31).

Chassis Type

Indicates the type of hub that houses this EMM-E6 — MMAC-M3FNB, MMAC-M5FNB, and so forth — and whether or not the hub contains a shunting backplane.

To change the name, location, contact, date, or time:

1. Highlight the appropriate ﬁeld and type the new values.

2. Press Enter or Return on the keyboard to save each change before moving on to another; each change will appear on the front panel as soon as Enter or Return is pressed.

The Device Status window also allows you to enable or disable the audible chassis alarm for your chassis. When the chassis alarm is enabled, an alarm will sound when high temperature or low voltage conditions occur in the chassis. To enable or disable the chassis alarm:

1. In the Audible Alarm State ﬁeld, click on the Enab led or Disabled option, as desired. The chassis alarm will be enabled or disabled, as selected.

Checking Network Status

The Network Status window provides information about each active repeating network, or channel, on the EMM-E6.

To access the Network Status window:

1. Click mouse button 1 in the appropriate Network Connection box (one displaying the letter that identiﬁes the network you are interested in: A, B, or C).
