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 8.5-inch rack-mounted size achieve high
density within a single rack. With 12 fiber ports to be deployed, the Managed Switch provides the
best performance and price ratio.
1.1 Overview of FOS-5112
FOS-5112, a compact 8.5-inch and rack mountable Managed Switch, has 8 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 half-size rack design in appearance,
FOS-5112 can be used in closet wiring as well, which is especially suitable for the small cabinet and
narrow space installation environment.

2.3.2 Rack Installation
Either you can install an 8.5-inch switch or two 8.5-inch switches in a standard 19-inch network
equipment rack. In the following sections, we will take a Managed Switch for example to separately
demonstrate how to mount it or them in this size of rack space.
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 a Managed Switch in a Rack
To install one set of the Managed Switch in a single rack space, you need the 19-inch rack-mount kit
supplied with the switch. Just follow the procedures listed below for step-by-step instructions to
install your switch in this rack space:
Step 1. Attach the supplied rack mounting brackets to the switch:
1.1. Attach the supplied regular mounting bracket to one side of the switch that you would
like to install in the rack. (See Figure 2-1)
1.2. Attach the supplied long mounting bracket to the other side of the switch. (See
Figure 2-1)
Step 2. Insert the screws provided in the rack-mount kit through each bracket and into the
bracket mounting holes in the switch. (See Figure 2-1)
