1. Summary
Switch-M24eGLPWR+ is an Ethernet Switching Hub with management function having 24 ports of 10/100/1000BASE-T
and two pairs of 10/100/1000BASE-T port and SFP extension slot, one of which is selectable.
Port 1 to 24 support IEEE802.3at PoE power supply function.
2. Features
(1) Has wire-speed Layer 2 switching function.
(2) 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 25 and 26 can be used as a 10/100/1000BASE-T port corresponding to auto negotiation or an SFP extension slot exclusively.
(3) Ports 1 to 24 can supply power conforming with IEEE802.3at. Supplying power up to 30 W per port, and up to 185 W in total is
possible.
(4) 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 16 are set at
MDI-X. (default))
(5) Telnet allows remote configuration changes and verifications of the Switching Hub. Remotely configure the PoE settings for each port
(Ports 1 to 24).
(6) Equipped with energy efficient Ethernet (EEE) conforming to IEEE802.3az (LPI).
When there is no data transmission at link up, the energy-saving state automatically starts so that power consumption can be
reduced on each port.
(7) Embedded power saving mode detects the connection status automatically and saves power consumption to minimum.
(8) VLAN function allows free grouping of up to 256 VLANs.
(9) The IEEE802.1w Rapid Spanning Tree Protocol is supported, allowing to build a system with redundancy.
(10) The IEEE802.1p compatible QoS function is supported.
(11) The IEEE802.1X compatible user authentication function (EAP-MD5/TLS/PEAP) is supported.
(12) Has an Internet Mansion function, which ensures security between each door.
(13) Due to the loop detection/shutoff function, a port where loop has occurred can be automatically shut off to prevent loop failures.
When a port is shut off and recovered automatically, SNMP trap can be sent to notify the incident to the administrator.
Moreover, the port with a loop can be identified by loop notification on the LEDs on the main unit and referring the history of loop
on the setting screen.
(14) The PoE scheduler function enables scheduling of PoE power supply control.

14. Basic Instructions for the Use of This Product
（1） Handle the Switching Hub carefully so that fingers or hands may not be damaged by twisted pair port, SFP extension slot,
console port, or power cord hook block.
（2） Do not connect any other devices except for 10BASE-T/100BASE-TX/1000BASE-T devices to the twisted pair ports.
Deviation could lead to equipment failure.
（3） Do not insert any other modules except for the our optional SFP module (PN54021K/PN54023K) to the SFP extension slots.
（4） Unplug the power plug when there is a malfunction.
Deviation could lead to fire if the power is allowed to be supplied for extended periods of time.
（5） Be sure to connect the ground cable.
Otherwise this might cause electrical shocks, misoperations and malfunctions.
Connect the Switching Hub via the supplied power cord to the outlet which is connected to the ground.
If the outlet is not connected to a ground, connect the ground cable to the ground terminal screw.
（6） Use the bundled power cord (AC 100 – 240 V specifications).
Deviation could lead to electric shock, malfunction, and/or equipment failure.
（7） Unplug the power cord in case of equipment failure.
Deviation, such as keeping connected for a long time, could lead to fire.
（8） Connect this Switching Hub to ground.
Deviation could lead to electric shock, malfunction, and/or equipment failure.
（9） Connect the power cord firmly to the power port.
Deviation could lead to electric fire, shock, and/or malfunction.
（10） Unplug the power cord if the STATUS LED blinks in orange (system fault).
Deviation, such as keeping connected for a long time, could lead to fire.
（11） 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.
（12） 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.
（13） 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.
（14） 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.
（15） 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.
（16） 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.
