wired LAN. Using a Power-over-Ethernet system, installers need to run only a single
Category 5 Ethernet cable that carries both power and data to each device. This allows
greater flexibility in the locating of network devices and, in many cases, significantly

There are two system components in PoE - the PSE (Power Sourcing Equipment) and
the PD (Powered Device). The IEEE 802.3af/at specification defines PSE as a device that
inserts power onto an Ethernet cable. The PSE may be located at the switch (Endspan
configuration). or it may be a separate device located between the switch and the PD
(Midspan configuration). The PD is the natural termination of this link, receiving the power,
and could be an IP phone, a WLAN access point, or any other IP device that requies
power. The current is transmitted over two of the four twisted pairs of wires in a
Category-5 cable.

Power-over-Ethernet follows the IEEE 802.3af/at specification and is completely compatible
with existing Ethernet switches and networked devices. Because the Power Sourcing
Equipment (PSE) tests whether a networked device is PoE-capable, power is never
transmitted unless a Powered Device is at the other end of the cable. It also continues to
monitor the channel. If the Powered Device does not draw a minimum current, because it
has been unplugged or physically turned off, the PSE shuts down the power to that port.
Optionally, the standard permits Powered Devices to signal th the PSEs exactly how
much power they need.

Unicom’s Micro-SwitchPoE/5 Switch is a multi-port switch that can be used to build
high-performance switched workgroup networks. This switch is a store-and-forward
device that offers low latency for high-speed networking. It also features a
“store-and-forward” switching scheme that allows the switch to auto-learn and store
source addresses in a 1K-entry MAC address table. The switch is targeted at workgroup,
department or backbone computing environments.

RJ-45 Ports ( Auto MDI/MDIX )

5 auto-sensing ports of 10/100 N-way for 10Base-T or 100Base-TX
connections. [ In general, MDI means connecting to another Hub or

Switch while MDIX means connecting to a workstation or PC. Therefore,
Auto MDI/MDIX means that you can connect to another Switch or
workstation without changing pin-to-pin or crossover cabling. ]

Micro-SwitchPoE/5 is designed as a segment switch that has a large address table and
high performance to deal with interconnecting networking segments.

PC, workstations, and servers can communicate with each other by directly connecting
with the . The switch automatically learns nodes addresses, which areMicro-SwitchPoE/5
subsequently used to filter and forward all traffic based on the destination address.

installed in more appropriate position for better performance. The following figure is an
example of network application for Power over Ethernet Switch.

Troubleshooting

This section is intended to help solve the most common issues with the Micro-SwitchPoE/5

Incorrect connections

Every port on this switch can automatically detect either straight or crossover cables when

(depending on the device). Choose the appropriate cable to connect between the units.
The RJ-45 connector should use correct UTP or STP cable, 10/100Mbps port use 2-pairs
twisted cable. If th RJ-45 connector is not correctly pinned then the link will fail.

you link it with other Ethernet devices but other devices may demand a specific cable type

Faulty or loose cables

Look for loose or obviously faulty connections. If they appear to be OK, make sure the
connections are snug. If that does not correct the problem, try a different cable.

Non-standard cables

Non-standard and miswired cables may cause numerous network collisions and other
network problems, and can seriously impair network performance. A cable tester is the
recommended tool for network installation.

RJ-45 ports: Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for
RJ-45 connections: 100 Category 3, 4 or 5 cable for 10Mbps connections, 100ΩΩ
Category 5 cable for 100Mpbs connections, or 100 Category 5e above cable forΩ/
1000Mbps connections.Also be sure that length of any twisted-pair connection does
not exceed 100 meters (328 feet). We suggest using Category 5e cable when connection
to power a device.

Improper Network Topologies

It is important to make sure that you have a valid network topology. Common topology
faults include excessive cable length and too many repeaters (hubs) between end nodes.
In addition, you should make sure that your network topology contains no data path loops.
Between any two ends nodes, there should be only one active cabling path at any time.
Data path loops will cause broadcast storms that will severely impact your network performance.

Diagnosing LED Indicators

To assist in identifying problems, the switch can be easily monitored through panel
indicators, which describe common problems the user may encounter and where the user
can find possible solutions. If the LED display detection isn’t correct, please unplug then
plug in the cable again.

If the power indicator does not light when the power cord in plugged in, you may have a
problem with the power outlet or power connections, power losses, or surges at power
outlet. If the problem still cannot be resolved, please contact the local dealer for assistance.
