Overview
4
You can configure up to eight AT-3600 Series hubs in a rackmount chassis.
When fully populated with AT-3624T and AT-3624TR hubs, the chassis
creates a single department concentrator with up to 200 ports (8 modules
with 24 network ports each, plus 8 AUI ports).
Figure 2 shows a sample department concentrator using an 8-slot chassis.
You can mount any combination of the following hub models in the same
department concentrator chassis: AT-3606F; AT-3606F/SMA; AT-3606F/
ST, SC, SM; AT-3608; AT-3612T; AT-3612TR; AT-3624T; AT-3624TR;
AT-3624TS; and AT-3624TRS.
Network management software will view the concentrator as a single
logical device. In this configuration the modules perform different
functions:
❑
The top module becomes the
Master
. It downloads software to, and
serves as, the reporting unit for other units in the concentrator. It
also controls management functions.
❑
The module in the slot directly below the Master becomes the
Backup
. It assumes management functions if the Master fails.
❑
All other modules function as
Slaves
. They report management
information to the Master but do not perform any control functions.
Each chassis must contain at least one manageable hub module to enable
network management. This module must occupy the uppermost slot in the
chassis. Because the uppermost manageable hub performs all
management reporting activities, it is referred to as the
Master
. The other
AT-3600 modules in the same chassis (except any Backup module that
may be installed) are called
Slaves
.
