Guidelines to Building a Stack
Here are the guidelines to building a management stack of AT-MCF2000
and AT-MCF2300 Chassis:
❒
A stack can have up to sixteen media converter modules.
❒
A stack can have both AT-MCF2000 and AT-MCF2300 Chassis.
❒
The maximum distance between two Stack ports is 100 meters (328
feet).
❒
The chassis containing the AT-MCF2000M Management Module has
to be at one end of the stack.
❒
The other units are connected to the stack with the AT-MCF2000S
Stacking Module.
❒
Each unit has to be assigned a unique chassis ID number from 0 to 31.
This number is set with a jumper on the AT-MCF2000M Management
Module and with DIP switches on the AT-MCF2000S Stacking Module.
The jumper and with DIP switches have to be set before the modules
are installed in the units because they are not accessible afterwards.
❒
The ID numbers of the units in a stack do not have to be sequential or
reflect the numerical positions of the chassis in the daisy chain
topology.
❒
The stacking feature does not require an IP address configuration on
the management module.
❒
A chassis that has the AT-MCF2000S Stacking Module has to be
managed through the stack because the module does not have a port
for local management.
❒
There cannot be any network devices, such as routers or Ethernet
switches, between two Stack ports.
❒
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.
❒
Disconnecting the stacking cables does not interfere with the
operations of the media converter modules because the stacking ports
carry just management traffic.
❒
The chassis ID numbers of the units are not adjustable through the
management software.
