AsantéHub 2072 Network Management Module Installation Guide Introducing the Network Management Module The Asanté 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 control AH2072 NMM or NetStacker modules, gather statistics, monitor network traffic, and set alarm thresholds.
Introducing the Network Management Module With the NMM’s Segment Control buttons, you can manually isolate any AH2072 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 segments of the AsantéHub 2072 and its repeater modules.
AsantéHub 2072 Network Management Module Installation Guide Installation The NMM installation consists of: ❏ ❏ ❏ ❏ Grounding Requirements Checking Package Contents 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.
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.
