Specifications

TurboStack Series Hubs
25
Since these models do not incorporate management agent software, they
can operate only as part of a non-managed hub or as Slave modules in an
ATI department concentrator chassis.
Features Table 4 summarizes the features of the AT-TS12FS/ST, SC, SM hubs,
including model number, port count, and media connector type.
Table 4: Features of AT-TS12FS Series of Hubs
The AT-TS12FS/ST, SC, SM series of hubs are IEEE802.3 compliant and
Ethernet compatible. When used in conjunction with a TurboStack Master
in a department concentrator chassis, these fiber models can support ATI’s
Omega Agent, Simple Network Management Protocol (SNMP), the second
version of the Management Information Base (MIB-II), and hub MIB.
For the AT-TS12FS/ST, SC, SM series of hubs to be manageable, another
hub must perform as a Master in the chassis.TurboStack hub models that
can function as a Master are listed in Chapter 1 of this manual.
Each manageable TurboStack hub is a single building block for both
standalone and chassis (department concentrator) configurations. ATI
supplies desktop and rackmount department concentrator chassis that
can hold up to eight TurboStack hubs.
Configurations The AT-TS12FS/ST, SC, SM series of hubs are commonly called a Slaves
because they depend on a Master hub for management. Each of the
AT-TS12FS/ST, SC, SM series of hubs can function in any of the following
four configurations:
❑ As a standalone repeating device without management: A
standalone Slave hub performs simple regeneration and retiming
tasks in a variety of network configurations. This configuration can
use the hub’s AUI port to connect to a network backbone.
❑ As a hub module in a chassis: Up to 8 Slave modules can be
mounted in a single 8-slot chassis with standard backplane to act
collectively as a single logical hub without a Master.
❑ As a managed module in a department concentrator chassis with
standard backplane and a Master.
❑ As a managed module in a department concentrator chassis with
segmented backplane and a Master.
