The NetStacker II Hubs
Thank you for purchasing an Asanté NetStacker II 12 port or 24 port hub. The
NetStacker II products ar e unmanaged dual speed stackable hubs which provide
a compact, flexible solution for medium to large workgroups and small office
LANS. These 12-port and 24-port hubs comply fully with IEEE802.3 and
IEEE802.3u standards.
Both the 12-port and 24-port hubs can be upgraded easily to managed hubs by
addition of an optional plug-in management module. This module slides into a
slot on the back panel of the hub. You do not need to purchase another hub to
gain full management capabilities - you can convert your unmanaged hub in a
matter of minutes.

Introduction
The NetStacker II 12 port unmanaged hub provides 12 twisted pair ports. The
24 port managed hub provides 24 twisted pair ports. In addition, both hubs
offer an expansion slot for a 100Base-FX interface so the user can slide a fiberoptic module into the rear panel. A slot for a 100Base-FX interface is also
provided on the front panel, for use when the management module has been
installed in the rear panel slot.
Both hubs automatically detect the speed (10Mbps or 100Mbps) of the devices
they are connected to. For additional expansion, each hub provides an Uplink
push-button for the 12th port, which can be cascaded to another hub by means
of straight through cable.
The NetStacker II hubs can be stacked up to 8 units high and connected by
means of the “Stack Connection In” and “Stack Connection Out” ports on the
rear panel. In addition, one of the hubs in the stack may be equipped with a
slide-in management module. The entire stack requires only one managed hub
for all of the stacked devices to be managed. Each dual speed hub has its own
ID, which is auto-detected and auto-configured. You do not have to configure
the hub ID yourself.
Either model hub can be placed on a tabletop or rack mounted. With
unmatched flexibility, the hubs ensure operation in any LAN environment,
regardless of size. The hubs provide the solutions that users require for their
complex networks.
