NetStacker NMM Lite Installation Guide
RS232 Connector You can use the RS232 connector on the NMM Lite back panel to
connect the NetStacker Hub to:
❏ An AsantéView Out-of-Band Management Station
❏ A modem
❏ A local terminal
Using out-of-band management, you can gather statistics and set
parameters for up to twelve stacks of Asanté NetStacker Hubs or
any combination of twelve daisy-chained hubs.
See Figure 3 on page 11 for an illustration of the RS232 connector
on the NMM Lite back panel.
Connecting a Modem to
the Hub
For remote management purposes, you can make a local connec-
tion from the RS232 serial port on the NMM Lite to a modem. You
can use this setup with AsantéView and the AsantéView Manage-
ment Station (AMS) to activate a pager when it receives a trap mes-
sage from a hub. This trap message causes the AMS to page this
event to the remote user. See the appropriate AsantéView User’s
Guide for information on setting up trap messages and paging
options.
The following procedure shows you how to connect a modem to
the hub. See Figure 9 on page 20 for an illustration.
1
Connect one end of the modem cable to the RS232
serial port (DB9 connector) of the end hub.
2
Set DIP Switch 2 UP for this hub.
∆ You will not be able to manage this hub using
AsantéView Out-of-Band via the local AMS Link
while DIP Switch 2 is in the
UP position. How-
ever, you can manage this hub using AsantéView
In-Band.
3
If you changed the DIP switch setting, you must reset
the hub. You can either press the
Reset button on the
NMM Lite back panel or reset the hub remotely using
AsantéView Lite.
