20 EX-3524/EX-3548 Layer 2 Gigabit Ethernet PoE/PoE+ Switch

3.4 Port Connecctions

3.4.1 Installing SFP Transceivers

The switch provides slots for optional (not provided) SFP transceivers. The supported transceiver types are listed
below:

• 1000BASE-SX

• 1000BASE-LX

• 1000BASE-LH

• 1000BASE-FX

• 1000BASE-T

NOTE SPF transceivers are hot-swappable. The switch does not need to be

powered off before installing or removing the transceiver.

To install a SFP transceiver:

1. Consider network and cabling requirements to select an appropriate transceiver type 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.

Installation Guide 21

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.

NOTE To remove a transceiver, disconnect the network cable then pull the tab

to remove the transceiver from the slot.

3.4.2 Connecting Twisted-Pair Cables

The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, which enables you to use
standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches,
routers, or hubs).

The connection requires an unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable with RJ-45
connectors at both ends.

Cable Type Maximum Cable Length Connector Type

100BASE-T
Category 5, 5e or 100-ohm UTP or STP

100BASE-TX
Category 5 or better 100-ohm UTP or STP

10BASE-T
Category 3 or better 100-ohm UTP

100 m (328 ft) RJ-45

100 m (328 ft) RJ-45

100 m (328 ft) RJ-45

To ensure proper operation when installing the switch into a network, make sure that the current cables are suitable
for 10BASE-T, 100BASE-TX, or 1000BASE-T operation. Check the following criteria against the current installation
of your network:

• Cable type: UTP or STP cables with RJ-45 connectors; Category 5, 5e or better cable for 1000BASE-T
connections, Category 5 or better for 100BASE-TX connections, and Category 3 or better for 10BASE-T
connections.

• Protection from radio frequency interference emissions

• Electrical surge suppression

• Separation of electrical wires (switch related or other) and electromagnetic fields from data based
network wiring

• Safe connections with no damaged cables, connectors or shields

3.4.3 Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing
that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable
installations, Category 5e (enhanced Category 5) or Category 6 cable should be used. The Category 5e and Category
6 specifications include test parameters that are only recommendations for Category 5. Therefore, the first step in

22 EX-3524/EX-3548 Layer 2 Gigabit Ethernet PoE/PoE+ Switch

preparing existing Category 5 cabling for running 1000BASE-T is a simple test of the cable installation to be sure
that it complies with the IEEE 802.3-2008 standards.

3.4.4 Power-over-Ethernet

The switch supports both IEEE 802.3af and IEEE 802.3at-2009 PoE standards that enable DC power to be supplied
from the switch’s RJ-45 copper ports to connected devices by utilizing certain pairs of the connecting Ethernet
cable.

For the EX-3524, the total PoE power delivered by all ports cannot exceed the 390 W power budget. This means up
to 12 ports can supply a maximum 30 W of power simultaneously to connected devices, or all 24 ports can supply
a maximum of 15.4 W.

For the EX-3548, the total PoE power delivered by all ports cannot exceed the 779 W power budget. This means up
to 24 ports can supply a maximum 30 W of power simultaneously to connected devices, or all 48 ports can supply
a maximum of 15.4 W simultaneously.

Any PoE-compliant device attached to a port can directly draw power from the switch over the Ethernet cable
without requiring its own separate power source. This capability gives network administrators centralized power
control for devices such as IP phones and wireless access points, which translates into greater network availability.

To connect 100BASE-T cables to RJ-45 ports:

1. Consider network and cabling requirements to select an appropriate transceiver type that is also
compatible with the switch transceiver support.

2. Attach the other end to an available port on the switch. Ensure each twisted pair cable does not exceed
100 meters (328 ft) in length.

3. As each connection is made, the Link LED (on the switch) corresponding to each port will turn on green to
indicate that the connection is valid.

Installation Guide 23

3.4.5 Connecting to SFP Ports

The switch provides four ports for SFP-compliant fiber-optic transceivers. All 1000BASE fiber optic ports operate at
1 Gbps full duplex. The 100BASE fiber optic ports operate at 100 Mbps full duplex.

Cable Type

100BASE-SX

62.5/125 micron multimode

50/125 micron multimode

100BASE-LX 9/125 micron single
mode

10BASE-LH 9/125 micron single
mode

NOTE

The length of fiber optic cable for a single switched link should not
exceed the relevant specified standards. However, power budget
constraints should also be considered when calculating the maximum
fiber optic cable length for a a particular link. Maximum distances may
vary for SFP vendors.

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. 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.

To connect cables to SFP transceiver ports:

1. Remove and keep the fiber port’s rubber plug. When not connected to a fiber cable, the rubber plug should
be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a
clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber optic cables will
impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

24 EX-3524/EX-3548 Layer 2 Gigabit Ethernet PoE/PoE+ Switch

3. Connect one end of the cable to the SFP port on the switch and the other end to the SFP port on the other
device. Since SFP connectors are keyed, the cable can be attached in only one orientation.

4. As a connection is made, check the Link LED on the switch to validate the connection is valid.

NOTE Ensure cables are properly secured and route them away from the switch

without exceeding the minimum bending radius for fiber cables (typically
a few inches). Use cable ties to bundle cables together and secure coiled
loops of excess cable. Do not let cables hang free supporting their own
weight or pull in any way that puts stress on the connectors.

Installation Guide 25

4 Switch Management

The RJ-45 Console port on the front panel of the switch is used to connect a console device to the switch for
out-of-band console configuration. The console device can be a PC or workstation running a VT-100 terminal
emulator, or a VT-100 terminal. A console cable is supplied with the switch for connecting to a PC’s RS-232 serial
DB-9 DTE (COM) port.

NOTE To connect to notebooks or other PCs without a DB-9 COM port, use a

USB-to-male DB-9 adapter cable (not supplied).

The serial port default settings are as follows:

• Default Baud rate - 115200 bps

• CharacterSize - 8 Characters

• Parity - None

• Stop bit - One
