2.6 Power Boot Up
When powering the switch, the system starts initialization and diagnostic operations. The behavior sequence of
the LED indicators are:
LEDs Behavior Period & Indication
MNGT-LED Green blink ~ 10 seconds
All port LEDs Yellow ON ~ 3 seconds
All port LEDs Green ON ~ 3 seconds
All port LEDs OFF ~ 0.5 second
MNGT-LED Green ON System boot finished & no error is found
MNGT-LED Yellow blink System error found after self diagnostics
2.7 Reset Button
The reset button is used to perform a reset to the switch. It is not used in normal cases and can be used for
diagnostic purpose. If any network hanging problem is suspected, it is useful to push the button to reset the
switch without turning off the power. Check whether the network is recovered.
The button can also be used to restore the software configuration settings to factory default values. The
operations are:
Operation Function
Press the button and release during switch operation Reset & boot up the switch. The behavior is
same as power boot procedure.
Press the button until MNGT-LED steady ON Boot & restore all factory default settings
2.8 Making UTP Connections
The 10/100/1000 RJ-45 copper ports support the following connection types and distances:
Network Cables
10BASE-T: 2-pair UTP Cat. 3, 4, 5, EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters
Auto MDI/MDI-X Function
This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to

-16-
MDI-X connection with the remote connected device automatically. No matter a straight through cable or
crossover cable are connected, the ports can sense the receiving pair automatically and configure themselves to
match the rule for MDI to MDI-X connection. It simplifies the cable installation.
Auto-negotiation Function
The ports are featured with auto-negotiation function and full capability to support connection to any Ethernet
devices. The port performs a negotiation process for the speed and duplex configuration with the connected
device automatically when each time a link is being established. If the connected device is also
auto-negotiation capable, both devices will come out the best configuration after negotiation process. If the
connected device is incapable in auto-negotiation, the switch will sense the speed and use half duplex for the
connection.
Port Configuration Management
For making proper connection to an auto-negotiation INCAPABLE device, it is suggested to use port control
function via software management to set forced mode and specify speed and duplex mode which match the
configuration used by the connected device.
2.9 Making Fiber Connection
The SFP slot must be installed with an SFP fiber transceiver for making fiber connection. Two equipped SFP
slots are capable to support 100Mbps and 1000Mbps optical fiber transceivers.
Your switch may come with SFP transceivers pre-installed in slots when it is shipped.
Installing SFP Fiber Transceiver
To install an SFP fiber transceiver into SFP slot, the steps are:
1. Turn off the power to the switch.
2. Insert the SFP fiber transceiver into the SFP slot. Normally, a bail is provided for every SFP transceiver.
Hold the bail and make insertion.
3. Until the SFP transceiver is seated securely in the slot, place the bail in lock position.
Connecting Fiber Cables
LC connectors are commonly equipped on most SFP transceiver modules. Identify TX and RX connector
before making cable connection. The following figure illustrates a connection example between two fiber
ports:

Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.
Port Speed Configuration
There are three options for configuring port speed via software for Port 9 and Port 10.
The options are:
Auto Auto-detection for the type of the installed SFP transceiver by reading DDM data
100Mbps transceiver: Non-auto-negotiation (forced), 100Mbps, full duplex
1000Mbps transceiver: Auto-negotiation, 1000Mbps, full duplex
100Mbps FDX Non-auto-negotiation (forced), 100Mbps, full duplex
1Gbps FDX Auto-negotiation, 1000Mbps, full duplex
Network Cables
Multimode (MMF) - 50/125m, 62.5/125m
Single mode (SMF) - 9/125m

2.10 Making PoE Connections
This section describes how to make a connection between a PSE port and a PoE PD device. In Model DC &
PoE, all copper ports are equipped with PoE PSE function. The ports are enabled to deliver power together
with network signal to a connected powered device via Cat.5 cable.
To make a PoE connection, the following check points should be noted:
1. For safety reason, the connected PoE PD (Powered Device) must be a IEEE 802.3at or IEEE
802.3af-compliant device. Incompliant devices are not supported by the PoE switch model.
2. The Cat.5 cables used for the connections must be 4-pair cables. The power is sent over the spare pairs (4,5)
(7,8) of the cable. The maximum distance supported is 100 meters.
3. The power voltage supplied to the switch must be within the following range to make PoE function
working.
The PSE ports are equipped with the following capabilities:
1. Detection for an IEEE 802.3af /802.3at compliant PD.
2. No power is supplied to a device which is classified non-IEEE 802.3af compliant PD.
3. No power is supplied when no connection exists on the port.
4. The power is cut off immediately from powering condition when a disconnection occurs.
5. The power is cut off immediately from powering condition when overload occurs.
6. The power is cut off immediately from powering condition when over-current occurs.
7. The power is cut off immediately from powering condition when short circuit condition occurs.
