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 FOS-5128
FOS-5128, a compact 19-inch and rack mountable Managed Switch, has 24 Gigabit SFP ports
(100/1000Base-X) and 4 SFP+ uplink ports (1G/10GBase-R) on 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/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, FOS-5128 can be used in closet wiring as well.

2. 4 x 1G/10GBase-R SFP+ UPLINK ports (Ports 25-28):
3. Console Port:
An asynchronous serial console port supports the RS-232 electrical specification.
The console port can be used to manage the device, and the serial console port
settings should be configured as 9600, 8, n, 1.
4. Digital Input (Dry Contact):
A voltage-free connector that is used to decide whether the trigger occurs or not by
detecting its open/close status. The configuration is as follows:
- Open: Logic Level 0
- Close: Logic Level 1
5. Reset Button:
Press the reset button for 5~10 seconds, then release it to restart the system.
Press the reset button for more than 10 seconds, then release it to reset the

2.3.2 Rack Installation
In the following section, we will take the FOS-5128 Managed Switch for example to install a 19-inch
switch in a standard 19-inch network equipment rack.
WARNING!
Please mount the Switch firmly in rack, otherwise it may fall and cause the
system damage and possible injury to personnel.
2.3.2.1 Install FOS-5128 Switch in a Rack
The Managed Switch can be mounted in an EIA standard-sized, 19-inch rack, which can be placed
in a wiring closet with other equipment. Rack mounting brackets are provided to mount the Switch.
Just follow the procedures listed below for step-by-step instructions to install your switch in this rack
space:
Step 1. Plan the rack position.
Step 2. Align the mounting holes in the brackets with the desired holes in the rack, and insert
screws through each bracket and into the rack. (See Figure 2-1)
Step 3. Then, tighten the screws with the screwdriver to secure mounting brackets to the rack.
Step 4. Please ensure that the ventilation holes are not blocked.

2.4 Powering on the Managed Switch
The Managed Switch can be used with AC power supply 100-240 V, 50–60 Hz, 0.6A~0.4A or DC
power supply 48V (Range: 44~52V), 1A. After the Managed Switch is turned on, the Power LED
indicators should light in green color and the FAN should spin. 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 in the front 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 24 SFP ports and 4 SFP+ ports on the front panel. These 24 SFP ports
can be plugged with 100Base-FX or 1000Base-X SFP Fiber transceiver. Uplink ports 25-28 can be
plugged with 1000Base-X SFP Fiber transceiver or 10GBase-R SFP+ Fiber transceiver. The
connection of the fiber port must be matched, i.e. Transmitter to Receiver, and vice versa.
2.6 Installing and Removing SFP/SFP+ Modules
2.6.1 Installing SFP/SFP+ Modules
To connect the fiber transceiver and LC/SC cable, use the following guidelines:
1. Position the SFP/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/SFP+ transceiver into the slot until it clicks intoplace.
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/SFP+ transceivers in the device.
1. Remove the protective plug from the SFP/SFP+ transceiver.
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/SFP+ transceivers in the
switch. The fiber port is now set up.

2.6.2 Removing SFP/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 theslot.
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.
