Chapter 1: Overview

ˆ The chassis with the AT-MCF2000M Management
Module must be at one end of the stack.
ˆ The other units are connected to the stack with the
AT-MCF2000S Stacking Module.
ˆ Each chassis must be assigned a unique chassis ID
number from 0 to 31. The ID number for the
AT-MCF2000M Management Module can be 0 or 31.
The range of the ID number for the AT-MCF2000S
Stacking Module is from 1 to 30. The AT-MCF2000M
Management Module has a jumper for setting the
number and the AT-MCF2000S Stacking Module has
DIP switches.
ˆ The ID numbers to the chassis of a stack do not have to
be sequential and they do not have to reflect the
numerical position of a chassis in the daisy chain
topology, relative to the chassis with the management
module.
ˆ The stacking feature does not require an IP
configuration on the management module.
ˆ A chassis with the AT-MCF2000S Stacking Module must
be managed through the stack because the module
does not have a port for local management.
ˆ There cannot be an intermediary network device, such
as a router or Ethernet switch, between two Stack ports.
ˆ The units in a stack function as independent media
converters. The traffic of a media converter channel on
a module is restricted to its channel and cannot
crossover to another channel in the same chassis or
another unit in the stack.
ˆ Since the stacking cables carry only management traffic
between the management module and the stacking
modules, the cables connected to the Stack ports can
be disconnected and reconnected at any time without
interrupting the flow of network traffic through the
channels on the media converter modules.
