3com SuperStack® II Dual Speed Hub 500 24-Port 3C16611-ME Scheda Tecnica

The SuperStack II 
PS Hub Family

The SuperStack II PS Hub family pro-
vides increased bandwidth and manage-
ment control built in at no extra cost
using these standard features:

• Up to 40 segments
• Port switching through software
• All nine groups of RMON on all

segments simultaneously

Transcend Network Supervisor is
shipped with all SuperStack II hubs.
With Transcend Network Supervisor,
network devices are automatically dis-
covered and network activity and stress
monitored through an intuitive graph-
ical interface to provide powerful, yet
easy-to-use network management.

Microsegmentation ensures that users
get optimal performance from the net-
work. Users can stack up to 10
SuperStack II PS Hub units, providing
up to 40 segments overall. The multi-
channel cascade built into the
SuperStack II PS Hub family supports
our Ethernet segments and a separate
management channel in a single cascade
cable. The separate management
channel allows full management of iso-
lated and switched segments. 

Users can be allocated and reallocated
easily from one segment to another via
software to suit operational needs. This

capability increases bandwidth by per-
mitting completely flexible allocation of
ports to any of four network segments
per unit. It also makes it extremely easy
to alter workgroups. Adds, moves, or
changes to user groups are simply a
matter of a few keystrokes from a man-
agement console.

The SuperStack II PS Hub 50 boosts
desktop performance with its internal
segment switch and Fast Ethernet
expansion slot. Customers can increase
bandwidth by segmenting their work-
groups and then connecting them into a
Fast Ethernet backbone or server.

100 Mbps downlink modules are

available in 100BASE-TX and
100BASE-FX versions and can be con-
figured to operate in half- or full-duplex
mode. The maximum distance sup-
ported is 100 meters over copper wire
or 2 kilometers over fiber optic cable 
(in full-duplex mode).

With the SuperStack II PS Hub family,
individual conversations between ports
are continuously monitored using the
RMON capability and are automati-
cally redistributed to free up valuable
network bandwidth. Balancing can be
triggered by time or by exceeding a uti-
lization threshold, making the process
entirely automatic.
