CHAPTER 1
INTRODUCTION
The MCC-16 Media Conversion Center is a 16-slot modular chassis that
holds up to 16 Conversion Modules (CMs). The MCC-16, shown in
Figure 1-1, can change twisted pair switch ports to different ports and/or
media types. It is designed for switches and can convert between Ring In
(RI), Ring Out (RO), lobe, and station ports, using twisted pair or
multimode fiber optic cabling.
The MCC-16 accommodates four different CMs. Each CM can support at
least two lobe ports which allow the connection of station ports,
commonly on switches. The MCC-16 is IEEE 802.5 and IBM compliant.
The conversion modules are discussed in Section 1.1 and Section 1.2.

•
1.1.1 Speed-Fault Protection
The CMs prevent an y de vice from entering the ring at the wrong speed by
wrapping (closing) the port to which the device is trying to insert. This
prevents the device from beaconing the ring.
1.1.2 Active Re-timing With Jitter Reduction Circuitry
Active Re-timing with Jitter Reduction Circuitry uses a dual-digital,
Phase Lock Loop (PLL) that utilizes First-In, First-Out (FIFO) processing
to track and accurately receive even poor quality signals. This circuitry
effectively reduces jitter on a ring and removes jitter budget restraints.
This permits the use of longer cable lengths and mixed media types
without penalty and supports 250 stations per ring.
1-3
INTRODUCTION
1.2 CONVERSION MODULES
Each CM has at least two RJ45 receptacles that can be used for attaching
the cable from a Token Ring station, such as a switch. CMs that have
RI/RO capability allow the connection of RI ports to RO ports
(and vice versa) on other devices to extend the ring. The RI/RO ports are
compatible with all 802.5 compliant devices including passive MAUs.
By using different CMs in the MCC-16, the installation can contain RI,
RO, lobe, and station ports of either multimode fiber or twisted pair cable
to meet the needs of almost any topology.
The MCC-16 backplane supplies the power for the CMs. Each
NOTE
CM provides media conversion and/or port-type switching per
module.
1.2.1 MCC-FRIO
The MCC-FRIO, with RI/RO capabilities, has a set of fiber
ST RI/RO ports that can connect to RI/RO ports on other devices
(e.g., TDRMIM-AT, TRFOT-2, or TRRMIM-4AT) to extend the ring. The
module also has two lobe ports to connect stations. Thus, stations
connected to either lobe port can communicate across the RI/RO
connections to other parts of the ring, and they will also communicate
with each other.
1.2.2 MCC-DFL
The MCC-DFL has two Fiber Optic T ranscei vers (FO Ts). Each FO T has a
twisted pair and fiber ST port. This allows signals transmitted over the
twisted pair to be converted into optical signals for transmission over
multimode fiber. You can configure each FOT as a RI/RO device or a
station/lobe device. A switch can be set so that connections can be made
to an 802.5J compliant device.
Cabletron Systems offers complete compatibility with vendor
NOTE
1-4
products that comply with the “new” 802.5J standard for fiber
RI/RO ports. Therefore, the MCC-16 offers connectivity to
products using 802.5J or Cabletron Systems fiber keying.
INTRODUCTION
1.2.3 MCC-CRIO
The MCC-CRIO has a set of twisted pair RI/RO ports that can connect to
other devices with RI/RO capability (e.g., TDRMIM-AT). It also has two
lobe ports. This allows for RI/RO connections and the connection of
two stations. It provides the same functionality as the MCC-FRIO
(see Section 1.2.1) except it has twisted pair RI/RO ports.
1.2.4 MCC-D2PM
The MCC-D2PM can serve as a pair of two-port Multi-Station Access
Units (MAUs) or a single four-port twisted pair MAU.

This chapter describes how to install:
• The MCC-16 in a 19-inch rack
• An MCC-PS power supply into the MCC-16
• A Conversion Module (CM) into the MCC-16
• Cable into a CM port
The chapter also details maximum cable lengths, station count limits, and
troubleshooting.
Only qualified personnel should perform installation
procedures.
2.1 INSTALLATION CONSIDERATIONS
Check that all cabling guidelines detailed in Appendix B have been met
before installing and operating the MCC-16. The following guidelines are

!
CAUTION
• The MCC-16 can be rack-mounted or placed on any horizontal
surface.
• Use a single phase 100 to 125 Vac (or 200 to 240 Vac) grounded po wer
source located within 6 feet (so the power cord can be connected) of
the installation site.
providing three inches of clearance on the sides, above, and
behind the MCC-16.
Also, ensure that the ambient temperature in the installation
location neither falls below 5°C nor e xceeds 40°C and changes
at a rate of no more than 10°C per hour.
• Ensure that any shelf on which an MCC-16 (fully-loaded) is placed
will support 40 pounds of static weight.
2-1
INSTALLATION
• A CM can be installed into any slot in the MCC-16.
• One MCC-PS supports any configuration; however, two are required
to support redundancy.
• Set jumpers and switches before installing a CM. You can use a
narrow, blunt-tipped instrument such as a screwdriver to flip switches.
The CM automatically restarts after you reinsert it in the MCC-16,
implementing the modified operational settings.
• To prevent damaging the component board, work with switches in a
well-lighted location and handle the instrument used to flip switches
cautiously. Avoid using a pencil to flip switches to prevent possible
problems associated with the accumulation of conductive graphite
dust on the switches. Avoid contact with other board components.
• Notify Cabletron Systems Global Call Center if you detect any
damage or missing parts during unpacking (see Preface).
2.2 UNPACKING AND HANDLING THE MCC-16

INSTALLATION
To unpack a CM:
1. Carefully remove the CM and other items from the shipping box.
You should have the following items:
• CM
• Quick Reference Card for the CM
Save the box and packaging materials for possible future repackaging
and shipment.
2. Remove the CM from the protective bag and place it on top of the bag
in a dry, static-free, dust-free area.
3. Inspect the shipment for any signs of damage.
2.6 INSTALLING A CM
Only qualified personnel should perform these procedures in
an activated MCC-16. It is recommended that all other
personnel shut down the MCC-16 before installing or
de-installing CMs to eliminate potential damage to the MCC-16
or the potential hazard of electrical shock.
Install a CM into the MCC-16 as follows:
1. Remove the protection panel from any CM slot in the MCC-16, as
shown in Figure 2-6.
(Note that on the first installation of a CM it will be necessary to
remove one of the 8-slot protection panels.)
Ensure that protection panels are fastened to the MCC-16 on
!
CAUTION
slots not occupied by CMs. This reduces safety hazards and
helps prevent problems associated with electro-magnetic
Interference (EMI).
