INSTALLATION
CHAPTER 1. INTRODUCTION
Thank you for purchasing this product from CTC Union. We hope this product is everything you wanted and more.
Our Product Managers and R&D team have placed a "quality first" motto in our development of this series of Ethernet
switches with the desire of providing a highly stable and reliable product that will give years of trouble-free operation.
In this chapter we will introduce hardware features of MSW-4424C series. In chapter 2, power installation and
bracket installation methods will also be provided. MSW-4424C series also offers a wide range of software features
that can be managed using serial console and CLI (command line interface), Telnet, SSH, HTTP (Web GUI) or SNMP
(Simple Network Management Protocol). Chapter 4 will detail all of the configuration settings by using an easy to
point and click Web interface which can be accessed from any available web browser.
1.1 Product Description
MSW-4424C is a layer 2+ managed Gigabit Ethernet switches that provides stable and reliable Ethernet
transmission for Carrier Ethernet access switch solution. MSW-4424C is designed in standard 1U 19-inch size and can
be mountable in standard 19-inch rack. To offer the best flexibility and scalability for network deployment, MSW-
4424C is equipped with 20 SFP-based 100/1000Mbps dual speed optical ports, 4 Combo (10/100/1000Mbps RJ-45 or
100/1000Mbps SFP) ports and 4 1/10Gbps dual speed SFP+ uplink ports
MSW-4424C series optionally incorporates redundant power modules. The supply derives its power from either
an AC power source and/or DC power source. When two modules are installed, they provide for power redundancy.
Fans are located on the rear panel of the device. The immediate fan condition can be observed via FAN LED on the
front panel (See page 13) or via Web management (See page 18).

The front of the MSW-4424C contains two power slots. Built-in power module or modules from factory are varied
based on the user’s order. You can have one AC power, one DC power, one AC and one DC power, two AC power
supplies or two DC power supplies. Next to power supplies, 20 SFP-based slots, 4 Combo ports, 4 SFP+ uplink ports,
one MGMT (management) port and one console port are provided. SFP-based slots are numbered 1 through 28, from
left to right as viewed from the front. The device can be configured via the MGMT or console port. Right next to the
power module on the left is the protective earth grounding terminal. It is highly recommended that a stable ground be
attached to this device so that any surges on power via LAN ports can be properly and safely shunted to ground.

INSTALLATION
CHAPTER 2. INSTALLATION
The MSW-4424C is designed to be placed on the flat desktop or be mounted in a standardized 19-inch rack for
rack-mount placement. The switch you purchase should come with rack-mounting brackets from the factory and these
brackets are used for rack-mounting installation.
Besides, MSW-4424C series is equipped with built-in power and fan modules. Types of power modules available
are AC, DC, AC+DC, two AC and two DC power modules. Fans which are not removable are located on the rear panel
of the device. If you need to repair fan modules, please contact your sales representatives.
In this section, we will provide necessary information about fiber connections, console connection, power
connection and wall-mounting installation. Definitions of LED indicators are also provided at the end of this section.
2.1 Fiber Connections
The MSW-4424C Series utilizes SFP modules for fiber transmissions. Each of the fiber ports has an associated
status LED to indicate the presence or absence of fiber link and will also flash when there is Ethernet activity on the
port. For port 1 to port 20, each of SFP cages may insert any standard SFP module and be configured for 100M or
1000M operation. For port 21 to port 24, they are dual media combo ports meaning that you can either use
10/100/1000M RJ-45 or 100/1000M SFP for service connection. For port 25 to port 28, each of SFP cages may insert
any SFP+ module that supports 1/10G Ethernet connectivity. Having SFP+ option for uplink connectivity offers
customers a wide variety of applications for data center, enterprise wiring closet and service provider transport.
Figure 3. Fiber Connections
2.2 MGMT Port Connection
The MSW-4424C has a MGMT (Management) port for in-band management via TCP/IP connectivity. The MGMT
port allows you to access Command Line Interface (CLI) using Telnet or Web management over TCP/IP using standard
web browsers.
When you use the switch for the first time or restore the switch to the factory defaults, you can use RJ-45 cable
to directly connect MGMT port to your management PC. Then, run a Telnet facility or web browser to communicate
with the device over a TCP/IP network using the default IP address 10.0.0.1. For Telnet connection, up to four active
Telnet sessions can access the Switch concurrently. After you successfully login to the switch, you can change the IP
address to the desired one (See Chapter 3 & 4 for setting up new IP address).
Figure 4. MGMT Port Connection
2.3 Console Port Connection
The MSW-4424C has an asynchronous terminal console port for local management via a serial terminal. The
terminal provides management via a CLI (Command Line Interface) which will be familiar to many networking
engineers. For most users, the CLI can be used to initially configure TCP/IP access so that further configuration can be
completed via the GUI (Graphical User Interface) and any web browser.

INTRODUCTION TO CLI
CHAPTER 3. INTRODUCTION TO CLI
3.1 Introduction
The MSW-4424C Series of L2+ Carrier Gigabit Ethernet switches provide a number of configuration/management
methods. The first and very basic is serial console access. This method is also called out-of-band management and is
only available when a terminal or administrator PC can be physically connected to the local MSW-4424C Series switch
at the CONSOLE port using RJ45 to RS-232 console cable. Accessing the switch via CONSOLE port allows the user to use
CLI (Command Line Interface) to manage and configure the device. The out-of-band management is relatively useful
when you lose the network connection to the device.
On the other hand, in-band management enables you to manage the device remotely using the device’s IP address.
Using in-band management enables you to use Telnet console (CLI) or web browser (GUI) to access the device. If you
plan on using in-band management, you need to configure the device’s IP address first before it can be accessed via a
LAN port.
The out-of-band management via console access, using a command line (CLI), is familiar to most network engineers.
For engineers that are not comfortable using CLI, this device can also be managed using any standard Web Browser in
a more user friendly 'point-and-click' method. Therefore, in most configuration scenarios, the console will only be
used to initially configure the MSW-4424C’s IP address, so that the device may be accessed via the other methods
which require working TCP/IP.
After the device has been properly configured for the application and placed into service, a third method of
configuration/management can be employed using Simple Network Management Protocol (SNMP). The operator will
use SNMP management software to manage and monitor the MSW-4424C Series switches on a network. This requires
some configuration of the device to allow SNMP management. In addition, the network management platform will
need to import and compile the proprietary MIB (management information base) file so that the manager knows
"how" to manage the MSW-4424C.
3.2 CONSOLE Operation
Using the provided accessory cable, connect the MSW-4424C "CONSOLE" port (RJ-45) to the PC terminal
communications port (DB9). Run any terminal emulation program (HyperTerminal, PuTTY, TeraTerm Pro, etc.) and
configure the communication parameters as follows:
Speed:
