AsantéHub 2072 Network Management Module Installation Guide
Introducing the
Network
Management
Module
TheAsanté 2072 Network Management Module (NMM) provides
overall network management for the AsantéHub
2072 or
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 con-
trol AH
2072 NMM or NetStacker modules,gather statistics,moni-
tor network traffic,and set alarm thresholds.Figure 1 shows an
example of the NMM front panel.
Figure 1 Asanté 2072 Network Management Module (NMM)
∆ You do not have to have an NMM in the chassis
for the repeater modules to function properly.
The NMM’s major purpose is to manage the hub
and gather network statistics.
The primary features of the NMM include:
❏
AsantéView management capability for in-band
and out-of-band
❏
Simple Network Management Protocol (SNMP)
support
❏
Segment control
❏
Remote network management via RS232
❏
Terminal connection via RS232
❏
Comprehensive LEDs
❏
Upgrading capabilities
❏
HubAlertAudio/VisualAid
Interfacing with AsantéView network management software,the
NMM allows you to proactively manage your network via in-band
and out-of-band management from either Apple Macintosh
®
or
MicrosoftWindows
®
PC platforms.
The NMM has built-in SNMP support.When running AsantéView
management software from a Macinosh or PC,you can control the
AsantéHub
2072 or NetStacker hub.
The NMM also supports both management information base (MIB)
I and II,as well as Asanté’s private MIB extension.

Introducing the Network Management Module
With the NMM’s Segment Control buttons,you can manually iso-
late any AH
2072 NMM or NetStacker module,or assign it to either
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 seg-
ments of the AsantéHub
2072 and its repeater modules.
The module’s RS232 port and its AsantéView Management Station
(AMS) Link offer remote (out-of-band) network management con-
trol.With these two connections and an AsantéView Management
Station,you can gather statistics and set parameters for as many as
twelve daisy-chainedAsanté hubs.You can also use the RS232 port
as a local management port.Used in this way with terminal emula-
tion software,you can gather statistics and set parameters for an
individualAsanté hub.
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 colli-
sions,misalignments,fragments,and short events,as well as seg-
ment utilization and collision percentages in bar graph form.
The NMM is easy to upgrade because it has Flash EEPROM mem-
ory.To upgrade to the latest hub software (image code),download
the NMM’s microcode upgrades from an AsantéView Management
Station or from a third party TFTP server directly through the net-
work.See the appropriate AsantéView User’s Guide or third-party
server documentation for more information on the upgrade proce-
dure.
The AsantéHub
2072 MIB is a text file distributed byAsantéTech-
nical Support.The file can also be obtained using anonymous FTP
(FileTransfer Protocol) fromAsanté’s Internet accessible FTP
server (see "AsantéTechnical Support" on page 2 for more infor-
mation).
For MIB compilation instructions,refer to your management con-
sole’s documentation.

AsantéHub 2072 Network Management Module Installation Guide
Installation The NMM installation consists of:
❏ Grounding yourself
❏ Checking package contents
❏ Installing the module and checking its LEDs
❏ Connecting the module to other devices
Grounding Requirements Before unpacking or handling the module,you must attach the
grounding strap (provided in the package) to your wrist to dis-
charge static electricity from your body or clothes.Attach the
clamp end to the hub chassis,which should already be grounded
properly.
Checking Package
Contents
TheAsanté AH 2072 NMM package contains the following items:
❏
Warranty card
❏
This installation guide
❏
AsantéHub 2072 NMM in anti-static packaging
There may also be a“Read Me First”sheet in the package.Always
read the“Read Me First”document before you install.It contains
the most up-to-date information about your installation (this infor-
mation may not be included in the manual).
Warranty Card Filling out your warranty card and sending it in promptly is impor-
tant.If you do not send it in within 30 days after the date of pur-
chase,you may not be eligible for the NMM’s 5-year warranty.
Installing the NMM This installation assumes that you have already installed the
AsantéHub
2072 or NetStacker chassis.To install the NMM,do the
following steps:
1
Observing the anti-static grounding procedures (see
“Grounding Requirements”earlier in this document),
remove the module from its anti-static packing.
∆
Handle the module only by its edges.Do not
touch chips or connectors.
▲ Do not force the module into a slot.Forcing the
module into a slot can damage the backplane.

Page 7
Installation
2
Align the module with the inside edges of the card
guides on any available slot in the chassis.Gently slide
the module in until you can begin tightening the
screws.See Figure 2.
Figure 2 Installing the NMM
3
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.

provide attachment to other hardware devices such as PCs,Macs,
or dial-up modems:
❏AsantéView Management System (AMS) Link
❏RS232 connector
AMS Link The AMS Link specifically provides the following types of device
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 twoAMS 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 theAMS Link for simultaneous out-of-band management.
Connecting Hubs in an
Out-of-Band Daisy-Chain To connect hubs in an out-of-band daisy-chain using theAMS Link
connector:
1Be sure the length of the daisy-chain,from the man-
agement station to the hub furthest away,is less than
2000 feet.
2Connect 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 sec-
ond hub.
Connect the hubs in a daisy-chain as shown in
Figure 4 on page 13.
3To enable termination in the Out-of-Band daisy-chain,
