Introducing the NMM Lite
Introducing the
NMM Lite
The Asanté Network Management Module Lite (NS-NMM), or
NMM Lite, is a daughter board specially designed to be mounted
on the double-height RJ45B or RJ21B module. Its function, as the
intelligence of the NetStacker hub, is to manage and gather statis-
tics on a single NetStacker hub or on a stack of NetStacker hubs.
To manage a NetStacker hub, you must have an NMM Lite (or an
AH2072 NMM), and AsantéView Lite In-Band and Out-of-Band net-
work management software, version 2.3 or later, installed on a
management station. You can also use full-featured AsantéView
In-Band and Out-of-Band, version 2.3 or later.
Mounted on an RJ45B or RJ21B module, the NMM Lite saves you a
slot on the NetStacker hub. While a standard AH2072 NMM occu-
pies a separate slot, it provides the additional feature of segment
switching, enabling you to assign a module to either Segment 1 or
Segment 2. The NMM Lite does not provide segment switching.
∆
The 24-port RJ45B and RJ21B double-height
repeater modules do not require an NMM to func-
tion. You need an NMM only if you want to man-
age the hub.
The RJ45B and RJ21B
Modules
The RJ45B and RJ21B modules are 24-port, dual-height modules
specially designed to accommodate the NMM Lite daughter board.
The NMM Lite does not provide network segment switching. All
ports on the NetStacker hub are set to Segment 1 and cannot be
switched to Segment 2.
∆
If you use the standard AH2072 NMM module in a
NetStacker stack, you have segment switching.
You can assign all ports on a module to either
Segment 1 or Segment 2.
