Important Requests on Protection from Lightning Strike
If you connect a network camera, a wireless access point, or other devices that can be
affected by a lightning strike (in particular, devices installed outdoors) to the twisted pair
port of this Switching Hub, a lightning surge current/voltage may be conducted to this
Switching Hub through the twisted pair cable, leading to malfunction. If you connect such a
device, it is strongly recommended that you install a surge protective device (SPD) on the
twisted pair port side of this Switching Hub.
A lightning surge current/voltage may be conducted to this Switching Hub through the
power supply or ground wire connected to the power port, leading to malfunction. If a
lightning surge current/voltage may flow in through the power supply or ground wire, it is
recommended that you install a surge protective device (SPD) on the power port side of this
Switching Hub.

This Switching Hub is to be periodically serviced in order to maintain its
performance.
Please choose a product administrator, and have them be sure to implement
periodic maintenance. When doing maintenance, check the inspection chart that is
posted on our website which has the requisite items listed on it.
When using this Switching Hub to design systems, use it after applying
appropriate measures such as setting up redundant configurations.
Communications failures might be generated due to causes such as malfunctions or
misoperations while the Switching Hub is being used.
When using this Switching Hub for applications which require extremely high
reliability, be careful to expend all possible means to ensure safety and
reliability.
This Switching Hub was not designed nor manufactured with the intention that it be
used for applications (in use with railways, aviation, and medical care, etc. whereas
the influence rate due to communications failures is extremely high in regard to
systems that directly affect systems and human lives) which require extremely high
reliability.
It is strongly recommended that a lightning arrester (SPD) be installed on the
twisted pair port side and the power supply side of this Switching Hub.
Malfunctions might be caused due to overcurrent and overvoltage due to the effects
of lightning strikes.
It is recommended that this Switching Hub be replaced about five years after it
has been installed.
This may vary depending upon conditions such as utilisation rates and usage
environments, but performance might decrease due to the age-related degradation,
etc. of components.
Be careful in regards to environmental restrictions whereby the Switching Hub
can be used.
Please isolate the business power lines and communications lines. Isolate distribution
lines and other distribution lines, and low current power lines, optical fiber cables,
metallic water conduits, and gas conduits, etc. Noise may be generated in the
communications lines which might cause communications glitches.

Basic Instructions for the Use of This Product

Product Outline
Switch-S24GPWR is an Ethernet Switching Hub with management function having 24
ports of 10/100/1000BASE-T.
Ports 1 to 24 support IEEE802.3af PoE power supply function.
1.1 Features

1
 Ports 1 to 24 are 10/100/1000BASE-T ports corresponding to auto negotiation.
Also their speed and communication mode can be switched by configuration.
 Ports 1 to 24 can supply power conforming with IEEE802.3af. Supplying power up
to 15.4 W per port, and up to 124 W in total is possible.
 All twisted pair ports support straight/cross cable auto sensing function. Simply
connect devices with straight cables, whether it is a terminal or a network device.
(This function does not work if the port communication configuration is set at Fixed
or Link Aggregation. Ports 1 to 22 are set at MDI-X. (default))
 Has the IEEE 802.3az (LP1)-compliant Energy Efficient Ethernet function (hereafter
referred to as EEE). This function automatically saves power when there is no data
communication in the linkup state, allowing a reduction in the power consumption
of each port.
 Embedded power saving mode detects the connection status automatically and
saves power consumption to minimum.
 VLAN function allows free grouping of up to 256 VLANs.
 The IEEE802.1p compatible QoS function is supported.
 Has a loop detection function, which notifies when a loop occurs with the
corresponding port LED and automatically shuts down the looped port.
 Has a loop detection history function, which notifies when a loop occurs with the
corresponding LED and enables a network administrator to identify the looped port
after the loop is removed.
 Using the PoE scheduler function, power supply control for PoE can be scheduled.

1.4 Basic operation
This Product does not have a power ON/OFF switch. Connect the supplied power
cord to this Switching Hub and connect the other end into an electric outlet.
This Switching Hub operates at AC 100 - 240 V (50/60 Hz).
When power is supplied, all the LEDs are turned ON.
Then, POWER LED (Power) lights in green, STATUS/ECO LED (Status/ECO mode)
lights in orange, and self-diagnosis of hardware is executed.
On completion of self-diagnosis, POWER LED (Power), STATUS/ECO LED
(Status/ECO mode) and the Switching Hub starts operation as a Switching Hub.
As this Switching Hub succeeds in communicating with a terminal connected to each
port, LED of the port lights up.
When the terminal is not operating normally, for example when power is not
supplied to the terminal, LED is not lighted.
