CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main features and applications of the switch.
1.1 Introduction
The ES-1124 is an Ethernet switch with 24 10/100Mbps ports and 2 GbE dual personality
interfaces for uplink. A dual personality interface includes one Gigabit port and one slot for a
mini-GBIC transceiver (SFP module) with one port active at a time.
See Appendix A on page 29 for a full list of features available on the switch.
1.1.1 Backbone Application
The switch is an ideal solution for small networks where rapid growth can be expected in the
near future. The switch can be used standalone for a group of heavy traffic users. You can
connect computers and servers directly to the switch’s port or connect other switches to the
switch.
In this example, all computers can share high-speed applications on the server. To expand the
network, simply add more networking devices such as switches, routers, computers, print
servers etc.
Figure 1 Backbone Application
1.1.2 Bridging Example
In this example application the switch connects different company departments (RD and
Sales) to the corporate backbone. It can alleviate bandwidth contention and eliminate server
and network bottlenecks. All users that need high bandwidth can connect to high-speed
department servers via the switch. You can provide a super-fast uplink connection by using a
Gigabit Ethernet/mini-GBIC port on the switch.

Moreover, the switch eases supervision and maintenance by allowing network managers to
centralize multiple servers at a single location.

CHAPTER 2
Hardware Installation and
Connection
This chapter shows you how to install and connect the switch.
2.1 Freestanding Installation
1Make sure the switch is clean and dry.
2Set the switch on a smooth, level surface strong enough to support the weight of the
switch and the connected cables. Make sure there is a power outlet nearby.
3Make sure there is enough clearance around the switch to allow air circulation and the
attachment of cables and the power cord.
4Remove the adhesive backing from the rubber feet.
5Attach the rubber feet to each corner on the bottom of the switch. These rubber feet help
protect the switch from shock or vibration and ensure space between devices when
stacking.

Chapter 2 Hardware Installation and Connection
ES-1124 User’s Guide

"Do NOT block the ventilation holes. Leave space between devices when
stacking.
For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front
and 3.4 inches (8 cm) at the back of the switch. This is especially important for
enclosed rack installations.
2.2 Mounting the Switch on a Rack
This section lists the rack mounting requirements and precautions and describes the
installation steps.
2.2.1 Rack-mounted Installation Requirements
• Two mounting brackets.
• Eight M3 flat head screws and a #2 Philips screwdriver.
• Four M5 flat head screws and a #2 Philips screwdriver.
"Failure to use the proper screws may damage the unit.
2.2.1.1 Precautions
• Make sure the rack will safely support the combined weight of all the equipment it
contains.
• Make sure the position of the switch does not make the rack unstable or top-heavy. Take
all necessary precautions to anchor the rack securely before installing the unit.
2.2.2 Attaching the Mounting Brackets to the Switch
1Position a mounting bracket on one side of the switch, lining up the four screw holes on
the bracket with the screw holes on the side of the switch.
Figure 4 Attaching the Mounting Brackets
2Using a #2 Philips screwdriver, install the M3 flat head screws through the mounting
bracket holes into the switch.

Chapter 2 Hardware Installation and Connection
ES-1124 User’s Guide 19
3Repeat steps 1and 2to install the second mounting bracket on the other side of the
switch.
4You may now mount the switch on a rack. Proceed to the next section.
2.2.3 Mounting the Switch on a Rack
1Position a mounting bracket (that is already attached to the switch) on one side of the
rack, lining up the two screw holes on the bracket with the screw holes on the side of the
rack.
Figure 5 Mounting the Switch on a Rack
2Using a #2 Philips screwdriver, install the M5 flat head screws through the mounting
bracket holes into the rack.
3Repeat steps 1and 2to attach the second mounting bracket on the other side of the rack.
