CHAPTER 2
REQUIREMENTS AND SPECIFICATIONS
Before you install the TRMIM-62A, review the installation requirements
and operating specifications outlined in this chapter. Failure to follow
these guidelines when installing the TRMIM-62A could result in poor
network performance.
2.1 INSTALLATION GUIDELINES
Observe the following guidelines when installing the TRMIM-62A:
•
The MMAC must be configured with an FNB, (either an
MMAC-3FNB, MMAC-5FNB, MMAC-8FNB or an
MMAC-M3FNB, MMAC-M5FNB, MMAC-M8FNB). A Token Ring
network cannot be established in an MMAC without an FNB
backplane.
•
The TRMIM-62A can only be installed into any slot on the
MMAC-M5FNB/M8FNB or MMAC-5FNB/8FNB except the
right-most management slot. It can only be installed into any slot on
the MMAC-M3FNB or MMAC-3FNB except the bottom
management slot.
•
Ensure that the MMAC hub into which you will be installing the
TRMIM-62A has the recommended number and type of power supply
modules. Refer to the documentation included with each MMAC
model for information about power supply requirements.
NOTE
The FNB is a full-height, full-width backplane that links
Cabletron Systems Token Ring products in the MMAC.
MMAC-3s, MMAC-5s, and MMAC-8s without an FNB can be
upgraded with an FNB, providing greater flexibility in
configuring your system. Contact your Cabletron Systems
representative for more information.
