CHAPTER 3
INSTALLING THE
CONCENTRATOR MODULE
This chapter contains instructions for installing your concentrator
module into a Cabletron Systems MMAC product and connecting
token ring stations at the concentrator module’s trunk coupling
unit (TCU) ports.
Check that all requirements listed in Chapter 2, Installation
Requirements/ Specifications
, have been met before installing and
operating the concentrator module. When you install your
concentrator module, the following guidelines will help you to
properly configure your system:
•
The concentrator module cannot be installed into the rightmost
slot, Slot 0. Slot 0 is reserved for specific management/
bridging/repeater modules.
•
When the concentrator module is being installed into an
MMAC-8, be sure that a PSM or PSM-R is installed in the
associated rear power supply slot. The PSM or PSM-R, Power
Supply Module is the source of power for MMAC modules.
One Power Supply Module is required for every two MIMs.
NOTE:
The PSM-R (Redundant Power Supply Module) is recommended
for use with the MMAC-8FNB (with a Flexible Network Bus).
•
Multiple token ring products, within an MMAC, are
automatically linked at power on, provided that the following
conditions are met:
- The MMAC must be configured with an FNB, (either an
MMAC-3FNB, MMAC-5FNB, MMAC-8FNB or an
MMAC-M8FNB). Without the FNB, the individual MIMs
will not be linked, but will form independent Token Ring
networks.
