Allied Telesis AT-S10 TurboStack - Manual (Page 12)

Overview
2
❑ Software upgrade through firmware cassette or downloading via
the network
❑ Redundant links help to ensure connectivity to a critical network
resource, such as the corporate backbone or a server
❑ Inventory control through storage of multiple addresses on MAC
address table
❑ Comprehensive security features to enable:
— Restricted access to the hub’s management interface
— Restricted access to specific ports
— Manual updates to the MAC address table by the user when
secure mode locks MAC address table (no learning)
The TurboStack Hub Configurations
Each manageable Turbo Stack hub is a single building block for both
standalone (hub) and chassis (department concentrator) configurations.
Allied Telesyn supplies the
Turbo Stack chassis that offers two
configurations to enable you to build and reconfigure your networks easily,
efficiently, and at minimum expense:
❑ A standard configuration where a fully populated department
concentrator behaves as a single hub in the network topology.
❑ A segmented configuration that holds up to six Turbo Stack hubs
and either an AT-TS90TR or an AT-TS95TR switch occupying the
bottom slot. Each hub is independently connected to the network
backbone through the switch.
The management hub in the uppermost slot is the master module. It
provides agent services for the entire concentrator. Should the master
module fail, the
backup takes over the master functions automatically
(as long as the backup module is also a managed hub). You can hot swap
any module to trace faults or reconfigure the concentrator without
network downtime or interrupting hub management functions.
The Turbo Stack series also includes “slave” modules that are not
manageable as standalone devices (the AT-TS12FS/XX, AT-TS24TS, and
AT-TS24TRS models). The slave models, however, can be managed
through a master module housed in the same department concentrator
chassis. In such a department concentrator chassis, the configuration,
status, and statistical information of slave hubs appear on the network
management displays and can be manipulated in the same way as the
data from the manageable modules.
NOTE
This manual refers to two or more chassis-mounted hubs as a department
concentrator. The term hub refers to either a standalone hub or a
department concentrator configuration. Each installed unit in a chassis is
called a module.
