1Switch Description
This chapter includes these sections:
◆“System Overview” on page 9
◆“Key Technical Specifications” on page 11
System Overview
The ECS4110-28P is a Gigabit Ethernet Layer 2 switch with 24 10/100/1000BASE-T
Power-over-Ethernet (PoE) ports, and four Small Form Factor Pluggable (SFP)
transceiver slots for fiber connectivity.
The switch also includes an SNMP-based management agent, which provides both
in-band and out-of-band access for managing the switch.
Power-over-Ethernet All of the 10/100/1000 Mbps ports on the switch support both the IEEE 802.3af and
IEEE 802.3at-2009 PoE standards that enable DC power to be supplied to attached
devices using wires in the connecting Ethernet cable.

General Installation Guidelines
– 13 –
General Installation Guidelines
Be sure to follow the guidelines below when choosing a location.
◆The installation location should:
■be able to maintain its temperature within 0 to 50 °C (32 to 122 °F) and its
humidity within 10% to 90%, non-condensing.
■provide adequate space (approximately five centimeters or two inches) on
all sides for proper air flow.
■be accessible for installing, cabling and maintaining the device.
■allow the status LEDs to be clearly visible.
◆Make sure twisted-pair cable is always routed away from power lines,
fluorescent lighting fixtures and other sources of electrical interference, such as
radios and transmitters.
◆Make sure that the unit is connected to a separate grounded power outlet and
is powered from an independent circuit breaker. As with any equipment, using
a filter or surge suppressor is recommended. Verify that the external power
requirements for the switch can be met as listed under “Power Supply Units” on
page 27.
Installation Precautions
Warning: This switch uses lasers to transmit signals over fiber optic cable. The
lasers are compliant with the requirements of a Class 1 Laser Product and are
inherently eye safe in normal operation. However, you should never look directly at
a transmit port when it is powered on.
Warning: When selecting a fiber SFP device, considering safety, please make sure
that it can function at a temperature that is not less than the recommended
maximum operational temperature of the product. You must also use an approved
Laser Class 1 SFP transceiver.
Caution: Before installing your switch, first review all the safety statements and
guidelines in the Regulatory and Safety Information document.
Caution: Installing the switch in a rack requires two people: One should position
the switch in the rack, while the other secures it using the mounting screws.
Caution: The earth connection must not be removed unless all supply
connections have been disconnected.

◆“How to Install the Switch in a Rack” on page 17
◆“How to Install the Switch on a Desktop or Shelf” on page 18
◆“How to Install an SFP Transceiver” on page 19
Rack Mount Guidelines
When rack mounting the switch, pay particular attention to the following factors:
◆ Rack Types: You can use any standard EIA 19-inch equipment rack with either
two or four posts. The bracket hole pattern should be spaced 1U (1.75 in. or
4.45 cm) apart.
◆ Rack Stability: Whenever possible, secure the rack to the building ceiling or
floor, particularly if you are located in a region where earthquakes are common.
◆ Rack Planning: When installing equipment in a rack, first plan how units can
be best arranged. Try to always mount the heaviest equipment at the bottom
of the rack.
◆ Temperature: Since the temperature within a rack assembly may be higher
than the ambient room temperature, check that the rack-environment
temperature is within the specified operating temperature range. See “Switch
Cooling Requirements” on page 16.
◆ Mechanical Loading: Do not place any equipment on top of a rack-mounted
unit.
◆ Circuit Overloading: Be sure that the supply circuit to the rack assembly is
not overloaded.
◆ Grounding: Rack-mounted equipment should be properly grounded.

Chapter 3 | Switch Chassis
Switch Cooling Requirements
– 16 –
Switch Cooling Requirements
Wherever the switch is located, be sure to pay close attention to switch cooling
requirements. The location should be well ventilated and provide unrestricted
airflow at the front, back, and sides of the switch. If the airflow is insufficient, it may
cause the switch to overheat and fail. Figure 3 shows the airflow through the
switch.
Figure 3: Switch Cooling
Rack/Cabinet Cooling When mounting the switch in an enclosed rack or cabinet, be sure to check the
following guidelines to prevent overheating:
◆Make sure that enough cool air can flow into the enclosure for the equipment it
contains.
◆Check that the rack or cabinet allows the hot air to exit the enclosure (normally
from the top) without circulating back into equipment.
◆If the enclosure has sides or doors with ventilation holes, make sure they are
not blocked by cables or other obstructions.
◆Route cables within the rack or cabinet to maximize the airflow.
◆When possible, do not completely fill the rack or cabinet with equipment, allow
some unused space within the enclosure for better airflow.

How to Install the Switch in a Rack
Before you start to rack-mount the switch, be sure to have the following items
available:
◆Four mounting screws for each device you plan to install in a rack—these are
not included. Be sure to use the rack mounting screws that are supplied with
the rack.
◆A screwdriver (Phillips or flathead, depending on the type of screws used).
To rack mount the switch, follow these steps:
Caution: Installing the switch in a rack requires two people: One should position
the switch in the rack, while the other secures it using the mounting screws.
1. Attach the brackets to the device using the screws provided in the Rack
Mounting Kit.
Figure 4: Attaching the Brackets
2. Following your rack plan, mark the holes in the rack where the switch will be
installed.
3. One person should lift the switch into the rack so that it is aligned with the
marked holes.
4. The second person should secure the switch in the rack, using four rack-
mounting screws (not provided).

6. If installing multiple switches, repeat steps 1 to 4 to mount the switches
following your rack plan.
How to Install the Switch on a Desktop or Shelf
The switch can be installed on any flat surface such as a desktop or shelf. To mount
the switch on a flat surface follow these steps:
1. Attach the four adhesive feet to the bottom of the first switch.

2. Set the device on a flat surface near an AC power source, making sure there are
at least two inches of space on all sides for proper airflow.
3. If installing a single switch only, go to “How to Connect to AC Power” on
page 23.
4. If installing multiple switches, attach four adhesive feet to each one. Place each
device squarely on top of the one below, in any order.
How to Install an SFP Transceiver
The switch provides slots for optional SFP transceivers. The supported transceiver
types are listed below:
◆1000BASE-SX
◆1000BASE-LX
◆1000BASE-LH
◆100BASE-FX
◆1000BASE-T
Note: SFP transceivers are hot-swappable. The switch does not need to be
powered off before installing or removing a transceiver.
Note: SFP transceivers are not provided in the switch package.
To install an SFP transceiver, do the following:
1. Consider network and cabling requirements to select an appropriate
transceiver type that is also compatible with the switch transceiver support.
2. If the SFP slot is covered with a rubber protective cap, remove the cap and keep
it for later replacement.
3. Insert the transceiver with the optical connector facing outward and the slot
connector facing down. Note that SFP transceivers are keyed so they can only
be installed in the correct orientation.
4. Slide the transceiver into the slot until it clicks into place. If you do not
immediately connect a cable to the port, use a rubber protective cap to keep
the transceiver optics clean.
