Introduction
CTS’s Managed Switch is designed to meet the emerging FTTX & Metro Ethernet requirements. Its
low profile appearance with 1U height and the standard rack-mounted size achieve the highest
density within a single rack. When massive fiber ports need to be deployed, the Managed Switch
provides the best performance and price ratio.
1.1 Overview of SWH-3112
SWH-3112, a compact and rack mountable Managed Switch, has 8 10/100/1000Base-T RJ-45 ports
+ 4 combo uplink ports (10/100/1000Base-T and 100/1000Base-X SFP) in the front panel. This
Managed Switch provides high performance, store and forward switching capability plus other
advanced features such as QoS, VLAN, Spanning Tree, LACP and so on.
LED indicators located on the front panel ease the users’ effort to monitor and manage the network
status. The built-in management module also allows users to configure, control and monitor the
system locally via console or remotely via SNMP_ based management system.
This Managed Switch is a typical SFP solution to Metro Ethernet application. Besides, it can be
used as a stand-alone switch. With the height of 1U and the standard-size rack design in
appearance, SWH-3112 can be used in closet wiring as well.

2.4 Powering on the Managed Switch
The Managed Switch can be used with AC power supply 100-240 V, 50–60 Hz. After the Managed
Switch is turned on, the Power LED indicator should light in green color. For more details about the
power LED description, please refer to Section 1.4 LED Definitions.
Power Failure
In the event of power failure, unplug the power that is plugged into the switch at the back of the
device. When power is resumed, plug the power back to the switch.
2.5 Connecting the Managed Switch to the
Network
Connect to Network
The Managed Switch has 8 10/100/1000BASE-T RJ-45 ports and 4 combo ports in the front panel.
These 8 RJ-45 ports can be plugged with 10/100/1000Base-T UTP cable. Uplink combo ports 9-12
can be plugged with 100Base-FX, 1000Base-X SFP Fiber transceiver or 10/100/1000Base-T UTP
cable. The connection of the fiber port must be matched, i.e. Transmitter to Receiver, and vice versa.

2.6 Installing and Removing SFP Modules
2.6.1 Installing SFP Modules
To connect the fiber transceiver and LC/SC cable, use the following guidelines:
1. Position the SFP transceiver with the handle on top.
2. Locate the triangular marking in the slot and align it with the bottom of thetransceiver.
3. Insert the SFP transceiver into the slot until it clicks into place.
4. Make sure the module is seated correctly before sliding the module into the slot. A click
sounds when it is locked in place.
Note: If you are attaching fiber optic cables to the transceiver, continue with the following step. Otherwise,
repeat the previous steps to install the remaining SFP transceivers in the device.
1. Remove the protective plug from the SFPtransceiver.
Note: Do not remove the dust plug from the transceiver if you are not installing the fiber optic cable at this
time. The dust plug protects hardware from dust contamination.
2. Insert the fiber cable into the transceiver. The connector snaps into place andlocks.
3. Repeat the previous procedures to install any additional SFP transceivers in the switch. The
fiber port is now set up.
2.6.2 Removing SFP Modules
To disconnect an LC/SC connector, use the following guidelines:
1. Press down and hold the locking clips on the upper side of the opticcable.
2. Pull the optic cable out to release it from thetransceiver.
3. Hold the handle on the transceiver and pull the transceiver out of the slot.

2.7 Connecting the Switch to Console Port
The switch supports a secondary means of management. By connecting the RJ45 to RS232 serial
cable between a COM port on your PC (9-pin D-sub female) and the switch’s RJ45 (RJ45) port, a
wired connection for management can be established.
