Introduction
This manual describes the field installation of a Multi-Tech MR9600-100 Controller (henceforth, MR9600-
100) into a CommPlete Communications Server chassis. This manual also contains a reference guide to the
commands that are used to configure and control the MR9600-100. For configuration instructions, refer to
the System Installation and Quick Start section of you CommPlete documentation set.
Product Description
The MR9600-100 is the system controller module for the CommPlete Communications Server. The
MR9600-100 contains a built-in Web, FTP, and Telnet server, an embedded SNMP agent, and an
unmanaged Ethernet switch module. Its complete management capabilities allow the CommPlete
Communications Server and its segments to be managed remotely across any TCP/IP network.

CommPlete Communications Server 3
Card Status LEDs
The lower part of the MR9600-100’s front panel contains 16 two-color LED indicators, one for each card
slot in the CC9600 chassis. The slots are numbered 1 through 16 from left to right. The LEDs indicate the
state of the device cards installed in the CC9600 chassis. When the MR9600-100 is turned on, the lights go
through the following sequence before they act as status indicators for the device cards.
1. The LEDs on the right side turn red and then turn green when the right SIMM passes its memory
test.
2. The LEDs on the left side turn red and then turn green when the left SIMM passes its memory test.
3. The LEDs stay green for about five seconds while the flash boot code waits for a handshake sequence
on the diagnostic serial port.
4. If none is detected (this is normal unless the firmware is being updated through the diagnostic port)
the main controller code starts running and the LEDs are turned off.
5. The LEDs are turned on and off, one at a time, red and green.
6. All LEDs turn green while the system starts up.
7. After the system has started, the LEDs reflect the status of the device cards. Each LED will be in one
of the following states, depending on the device card.
LED Color Device Card Status
Off Card not installed.
Green Card installed and all devices are communicating with the MR9600-100.

100BASE-TX Technology Overview
100M bps Fast Ethernet is a relatively new standard specified by the IEEE 802.3 LAN committee. It is an
extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while
maintaining the CSMA/CD Ethernet protocol. Since 100Mbps Fast Ethernet is compatible with all 10Mbps
Ethernet environments, it provides a straight-forward upgrade without wasting your investment in
hardware, software, and personnel training.
The MR9600-100 provides an easy, affordable, high-performance, seamless, and standards-based
migration path to a 100BASE-TX LAN while preserving your initial investment and use of 10Mbps
Ethernet LANs.
The MR9600-100 complies with IEEE802.3u, 100BASE-TX, IEEE 802.3 and 10BASE-T standards. The
MR9600-100 has five 10Mbps twisted-pair ports and two 100Mbps twisted-pair ports. The MR9600-100
provides a store-and-forward token passing scheme. Filtering and forwarding rates for the MR9600-100
run at wire-speed, reducing latency within and across segments.
Cables and Connectors
The MR9600-100 supports Category 5 unshielded twisted-pair (UTP) cables. Cat 5 UTP cable uses the
same RJ-45 connector used with 10BASE-T, wired in the same configuration. Please note that the punch-
down blocks in the wiring closet must also be Category 5 certified. Where these blocks do not meet the
standard, an upgrade is necessary.
Topology
A Fast Ethernet workgroup is configured in a star topology and is built around a maximum of two
repeaters. Each workgroup forms a separate LAN (also known as a “segment” or “collision domain”), and
these workgroups can be easily interconnected through switches, bridges, or routers to form one LAN
large enough to encompass a high-rise building or campus environment. Recent innovations in LAN hub

1 Introduction
CommPlete Communications Server 7
technology such as stackable hubs, coupled with the decreasing cost of switches, bridges, and routers,
allow the design of low-cost, efficient Fast Ethernet workgroups and enterprise LANs.
The following factors strongly influence the architecture of Fast Ethernet networks:
•The EIA/TIA 568 Wiring Standard imposes a 100 meter limit on horizontal runs of twisted-pair cables;
that is, connections from the wiring closet to the end-station.
•Fast Ethernet’s increased operational speed reduces the maximum distance between all elements of the
LAN (see below).
•The EIA/TIA 568 Wiring Standard does not support the use of coaxial cables for horizontal wiring.
Network
The network diameter, which is the distance between two end-stations in the same collision domain, is the
primary difference between traditional Ethernet and Fast Ethernet. Due to the increased speed in Fast
Ethernet and adherence to the EIA/TIA 568 wiring rules, the network diameter of a Fast Ethernet collision
domain is limited to 205 meters; in contrast, the maximum 10BASE-T Ethernet collision domain diameter
can be up to 2500 meters.
Hubs
While 10BASE-T hubs are all functionally identical, Fast Ethernet hubs are divided into two distinct types:
Class I and Class II. A Class I hub repeats all incoming signals on one port to the other ports by first
translating them to digital signals and then retranslating them back to line signals. These translations are
necessary when connecting various network media to the same collision domain, such as when combining
two wire-pair 100BASE-TX media with four wire-pair 100BASE-T4 media. Only one Class I hub can exist
within the same collision domain, thus this type of hub cannot be cascaded. A Class II Hub (or
“repeater”), on the other hand, immediately repeats all incoming line signals on one port to the other
ports; no translations are performed. This type of hub connects identical media to the same collision
domain; for example, TX to TX. At most, two Class II hubs can exist within the same collision domain.
The cable used to cascade these hubs is called an inter-repeater link (IRL).
As mentioned earlier, stackable hubs can be used to increase the number of available nodes in a collision
domain. An entire hub stack counts as a single hub (repeater).
Connectivity Rules
•The maximum length of a twisted-pair segment (that is, distance between a port in the hub to a single-
address network device such as a PC, server, or LAN switch) is 100 meters.
•The maximum diameter in a collision domain is about 205 meters using two Class II hubs (or hub
stacks) and 200 meters using one Class I hub.
•Between any two end-stations in a collision domain, there may be up to three segments and two Class
II hubs or two segments and one Class I hub.
Switching Technology
Switching is fast becoming the industry standard for pushing the limits of existing Ethernet networks. A
switch bridges Ethernet packets between Ethernet and Fast Ethernet LAN segments at the MAC address
level of the Ethernet protocol.

MR9600-100 User Guide
8CommPlete Communications Server
The difference between switched Ethernet (10Mbps, 100Mbps, or both) and traditional Ethernet is
analogous to the difference between a private phone line and a party line. With switched Ethernet, each
workgroup has a “private line” so that transmitted packets don’t have to wait as long to gain access to the
network. When connected to a switched port, each Ethernet segment has full “wire-speed” access, so a
switch effectively divides a single Ethernet LAN into bridged multiple LAN segments. Each segment can
support a workgroup or even provide a dedicated connection for a key workstation or server. The result of
dividing an Ethernet LAN into multiple segments is a multiplication of internal bandwidth available to all
stations on the LAN and a reduction in latency rates during peak-use periods.
Benefits of Switching
Ethernet switching technology drastically increases the total bandwidth of a LAN. It also provides
configuration flexibility to local workgroups which allows the network administrator to better control how
network resources are distributed against network load. Switching helps reduce the congestion problems
inherent in the contention-oriented CSMA/CD protocol, thereby improving network response during high
utilization periods.
Also, currently popular distributed client/server applications often require higher bandwidth and tighter
client-to-server integration. Legacy 10Mbps Ethernet often is unable to provide a sufficiently
sophisticated platform for users to be able to take full advantage of such client/server applications.
Fast Ethernet switching not only satisfies both technical and business needs, it also preserves the current
investment in the huge 10BASE-T Ethernet installed base. Compatibility with 10Mbps Ethernet ensures
that users will be able to migrate to Fast Ethernet at a pace appropriate to their installation and needs.
10/100 Switching Technology
An integral extension of Fast Ethernet, 10/100 switching provides not only a 100Mbps high-speed
connection for carrying aggregated 10Mbps traffic, it also handles the necessary conversion of the MAC
layer between 10BASE-T and 100BASE-TX. Combining Fast Ethernet and switching technologies provides
both bandwidth for local workgroups and a high-speed link to carry local traffic elsewhere in the network.

Introduction
This chapter describes how to install the MR9600-100 Controller into a CommPlete Communication Server
CC9600 chassis. This equipment should only be installed by properly qualified service personnel.
The MR9600-100 Controller assembly consists of the MR9600-100 Controller card, an integrated Ethernet
switch card, and a common front panel. Figure 3 shows the layout of the MR9600-100 card without the
switch. The MR9600-100 assembly plugs into bus connectors on the inside of the CC9600 chassis. Three
communications connectors on the switch module are accessible from the back of the CC9600 chassis: a
DB-9 serial connector for MR9600-100 diagnostics and configuration, and two 10/100M bps connectors for
network access.

Installation Procedure
1. Unpack the MR9600-100 assembly from its packaging, and save the packaging for possible future
use. Perform a visual inspection of the MR9600-100. If you are concerned about the condition of the
MR9600-100, call Technical Support for instructions.
2. Remove the blank controller panel or previous MR9600-100 controller from the CC9600 chassis. The
MR9600-100 is hot-swappable.
3. Holding the MR9600-100 by its handle and the edges of the bottom panel, place the MR9600-100
into the open controller slot of the CC9600. Make sure the edges of the MR9600-100 card mate
properly with the plastic guides in the CC9600.
4. Slide the MR9600-100 into the CC9600 chassis until you feel the MR9600-100’s connectors fit into
the bus connectors at the back of the CC9600.
5. Tighten the MR9600-100's retaining screws.
6. Turn on the PS9600 power supplies, if they are off.
7. Note the PS9600 LED indicators. If they are not lit, see Chapter 6. If they are lit, proceed with
MultiModemManager operation (Chapter 4 of the MultiModemManager
User Guide manual).
Note: A self-test runs each time the CommPlete Communications Server is turned on. Refer to Chapter 5
of the MultiModemManager User Guide manual for more details on the power-on self-test.
Ethernet Cabling
Two female 10/100M bps connectors are accessible from the back of the CC9600 chassis. Connect one of
these connectors to the TCP/IP network that the supervisor console is attached to. The supervisor console

CommPlete Communications Server 13
is the PC that runs the MultiModemManager software or, optionally, a third-party SNMP manager. Note
that for 10M bps connection, you can use Category 3 (Cat 3) or Cat 5 cable; for 100M bps connection you
must use Category 5 (Cat 5) cable.
Serial Cabling
Use the 9-pin RS-232 connector on the back of the CC9600 chassis for diagnostics and configuration.
Network Connections
If any port on the MR9600-100 is set for full duplex operation, the device (or LAN) connected to that port
must also be set for full duplex operation. Refer to the following sections on 10M bps and 100M bps ports
for specific requirements.
10M bps Ports
The five 10M bps ports are used internally for the four CommPlete segments and the Controller. The 10M
bps ports operate at a user-selectable effective speed of 10M bps in half-duplex mode, or at 20M bps in
full-duplex mode. In either mode, the twisted-pair connector can operate over 100 meters of Category 3, 4,
or 5 UTP/STP cable. Note that the MR9600-100 back panel has two RJ-45 connectors. Refer to Figure 2 for
the proper connector type (cross-over or straight through).
100M bps Ports
The two 100M bps ports use standard RJ45 twisted-pair connectors with unshielded or shielded twisted-
pair (UTP/STP) wiring. The 100M bps ports operate at an auto-negotiable neffective speed of 100M bps
(in half-duplex mode) or 200M bps (in full-duplex mode). In either mode, the twisted-pair connector can
operate over 100 meters of Category 5 UTP/STP cable. (Cat 3 cable can be used if the 100M bps port is
running at 10M bps.)
The two 100M bps ports can auto-negotiate for 10/20/100/200M bps operation. Note that the MR9600-100
back panel has two RJ-45 connectors. Refer to Figure 2 for the proper connector type (cross-over or
straight through).

Cable Types
Under most conditions, the ports on the MR9600-100 may use normal straight-through cables. Some
circumstances, however, may require cross-over cables (i.e., cables in which the twisted-pair outputs have
been crossed). See Appendix B for more information on cable pinouts.

MR9600-100 User Guide
14 CommPlete Communications Server
Setting the Duplex Mode (JP1-JP5)
Each 10M bps port can be set for half-duplex or full-duplex operation. At half-duplex operation, packet
transmission and reception do not occur simultaneously, thus communication speed is limited to 10Mbps
in 10BASE-T mode. At full-duplex operation, packet transmission and reception occur simultaneously,
thus communication speed is doubled to 20Mbps using 10BASE-T mode. Full-duplex operation can be
used on links between the MR9600-100 and any device (or station) that supports full-duplex operation.
Set the 10M bps duplex mode using jumpers JP1-JP5 on the top PCB located behind the front panel.
To set a port (e.g., “P1”in the figure below) to full-duplex operation, jumper the top two pins together for
that port.
To set a port (e.g., “P5”in the figure below) for half-duplex operation, jumper the bottom two pins
together for that port.
Refer to the figures below for 10M bps Half-duplex/Full-duplex mode jumper locations and settings. Note
that it is not necessary to turn off power to the MR9600-100 when changing the duplex mode setting.
