The Asanté 2072 Network Management Module (NMM) provides
overall network management for the AsantéHub
NetStacker hub. By plugging the module into any one of the
expansion slots in the chassis, the NMM works with the
AsantéView network management software to monitor and con­trol AH
tor network traffic, and set alarm thresholds. Figure 1 shows an
example of the NMM front panel.

of the chassis’ two segments. This can also be accomplished
remotely using AsantéView In-Band and Out-of-Band software.
Segment Control allows you to monitor and control both seg­ments of the AsantéHub

The module’s RS232 port and its AsantéV iew Manag ement Station
(AMS) Link offer remote (out-of-band) network management con­trol. With these two connections and an AsantéView Management
Station, you can gather statistics and set parameters for as many as
twelve daisy-chained Asanté hubs. Y ou can also use the RS232 port
as a local management port. Used in this way with terminal emula­tion software, you can gather statistics and set parameters for an
individual Asanté hub.

NMM or NetStacker module, or assign it to either

2072

and its repeater modules.

LEDs for both Ethernet segments are displayed on the NMM front
panel or can be viewed from an AsantéView Management Station.
The LEDs display many types of traffic statistics, such as late colli­sions, misalignments, fragments, and short events, as well as seg­ment utilization and collision percentages in bar graph form.

The NMM is easy to upgrade because it has Flash EEPROM mem­ory . To upgrade to the latest hub software (image code), download
the NMM’s micr ocode upgrades from an AsantéV ie w Management
Station or from a third party TFTP server directly through the net­work. See the appropriate AsantéView User’s Guide or third-party
server documentation for more information on the upgrade proce­dure.

MIB is a text file distributed by Asanté Tech­nical Support. The file can also be obtained using anonymous FTP
(File Transfer Protocol) from Asanté’s Internet accessible FTP
server (see "Asanté Technical Support" on page 2 for more infor­mation).

For MIB compilation instructions, refer to your management con­sole’s documentation.

Contents

The NMM installation consists of:

❏

Grounding yourself

❏

Checking package contents

❏

Installing the module and checking its LEDs

❏

Connecting the module to other devices

Before unpacking or handling the module, you must attach the
grounding strap (provided in the package) to your wrist to dis­charge static electricity from your body or clothes. Attach the
clamp end to the hub chassis, which should already be grounded
properly.

Installing the NMM

Filling out your warranty card and sending it in promptly is impor­tant. If you do not send it in within 30 days after the date of pur­chase, you may not be eligible for the NMM’s 5-year warranty.

This installation assumes that you have already installed the

Hand-tighten the module to the chassis. Make sure you
fasten both spring-loaded screws in unison and apply
the same amount of torque so that the module
attaches evenly to the chassis.

4

If the power to the hub was on when you installed the
NMM, reset the hub. If you powered down the hub
before installing the NMM, power up at this point.

5

Check that the CPU LED (located to the right of the
Reset button) blinks. A blinking CPU LED indicates
that the NMM is functioning properly.

Other Devices

AMS Link The AMS Link specifically provides the following types of device

Connecting Hubs in an

Out-of-Band Daisy-Chain

The NMM’s front panel has two connections (out-of-band) that
provide attachment to other hardware devices such as PCs, Macs,
or dial-up modems:

❏ AsantéView Management System (AMS) Link
❏ RS232 connector

connections:

❏ PC and Macintosh connections for Out-of-Band

network management

❏ Hub interconnections for out-of-band (daisy-

chained from one hub to another)

The two AMS Link connectors are RJ-45 ports that provide an
interface to a PC or Macintosh running AsantéView Out-of-Band
management software. You can daisy-chain as many as twelve hubs
via the AMS Link for simultaneous out-of-band management.

To connect hubs in an out-of-band daisy-chain using the AMS Link
connector:

1

2

3
4

Be sure the length of the daisy-chain, from the man­agement station to the hub furthest away, is less than
2000 feet.

Connect a straight-through RJ-45 extension cable (not
provided in the package) from an AMS Link connector
on the first hub to an AMS Link connector on the sec­ond hub.

Connect the hubs in a daisy-chain as shown in
Figure 4 on page 13.

To enable termination in the Out-of-Band daisy-chain,
set DIP Switch 1

On all other hubs in the chain, set DIP Switch 1 UP
