1. Product Outline
Switch-M16eG is an all Giga bit Ethernet Switching Hub with management function having 14
ports of 10/100/1000BASE-T and two pairs of 10/100/1000BASE-T port and SFP extension
slot, one of which is selectable.
1
1. .1 1. . F Fe ea at tu ur re es s
Has wire-speed Layer 2 switching function.
Ports 1 to 14 are 10/100/1000BASE-T ports corresponding to auto negotiation. Also their
speed and communication mode can be switched by configuration. Ports 15 and 16 can
be used as a 10/100/1000BASE-T port corresponding to auto negotiation or an SFP
extension slot exclusively. Also their speed and communication mode can be switched by
configuration.
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 14 are set at MDI-X. (default))
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.
VLAN function allows free grouping of up to 256 VLANs
Fanless design solves noise problem or fan failure.
Use of LED indicator switching button saves power consumption of LED lamps.
The IEEE802.1p compatible QoS function is supported.
Has an Internet mansion function, which ensures security between each door.
Power saving mode detects the connection status automatically and saves power consumption
to minimum.
Telnet and SSH functions facilitate remote setting change and confirmation.
Standard MIB (MIB II, Bridge MIB, etc.) is supported, enabling remote control by using
the SNMP manager. (For details, refer to Appendix A and Appendix C.)
Link aggregation function is supported. Aggregation can be manually configured up to 8
ports.
Reboot timer function is supported, enabling auto reboot after a scheduled time (24 hours
or less).

1.4.1. LED Behavior at Start-up
Upon turning this Switching Hub on, all LEDs tentatively light up. Then, the self-diagnosis
of hardware is executed. Upon finishing the diagnosis, power LED and status/ECO mode LED
light in solid green. Then, the Switching Hub starts working.

Fig. 1-4 Port LED
1.4.3. Loop detection function
Turns on the port LED with an orange light when a loop occurs in the corresponding port.
At this time, the relevant port automatically shuts down (default setting: 60 sec.) to prevent
loop from occurring. If the loop is still not removed, the port will shut down again. Remove
the loop while the port is shut off.
The loop detection/shut-off function can be switched on/off by keeping pressing the LED display
switch button for more than 10 seconds or by setting in the configuration menu. For details
on the configuration menu, refer to 4.7.5. If switching properly takes place, LOOP HISTORY
LED turns on to complete switchover.
The loop history can be reset by powering off the Switching Hub and then on.

1.5.1. Setting LED Base Mode
You can select display of LEDs in this Switching Hub from two types: Status mode and Eco
mode.
The mode selected at system start-up is called the base mode. The base mode can be switched
by keeping pressing the LED display switch button for more than 3 seconds. After pressing
the LED display switch button for more than 3 seconds, STATUS/ECO, GIGA, 100M, and
FULL LEDs will turn on at once, and then the mode will switch over.
Status mode (Factory default setting)
According to the port LED display mode, port LED shows the status of each port. In status
mode, STATUS/ECO LED lights in green.
ECO mode
Regardless of whether a device is connected or not, all LEDs other than POWER and
STATUS/ECO LEDs turn off to save power. In ECO mode, STATUS/ECO LED flashes in green.
The base mode can be set from the configuration menu of this Switching Hub. For details,
refer to 4.6.7.c.
1.5.2. LED Display Switchover
By pressing the LED display switch button on the front panel, display of port LED can be
changed in the following order.
Port LED display mode Description
STATUS/ECO Shows link establishment and communication status.
GIGA Shows linkup status at 1000 Mbps.
100M Shows linkup status at 100 Mbps.
FULL Shows linkup status at full-duplex or half-duplex.
LOOP HISTORY Shows loop detection and port shut-off status.
If the port LED display mode is switched to other than STATUS/ECO and then no operation
is executed for more than 1 minute, the mode automatically shifts to the base mode.

Take out the supplied 4 rubber feet (with built-in magnets), and place the Switching Hub
upside down. Fix the 4 rubber feet firmly to the Switching Hub using 4 screws (for magnetic
mount).

Note: Don't install the Switching Hub in such places as the unstable location, where there
is strong vibration or shock, or where a person may walk under this Switching Hub.
Deviation could lead to injury and/or equipment failure.

main unit and the mounting bracket), and fix the brackets to the main unit by tightening screws
into 4 holes located at the sides. Then, mount this Switching Hub firmly to the rack using
the supplied 4 screws (for 19-inch rack) or screws furnished at the rack.

3. Connection

3. .1 1. . C Co on nn ne ec ct ti io on n U Us si in ng g a a T Tw wi is st te ed d P Pa ai ir r P Po or rt t
Connection Cable
Use a CAT5E or higher twisted pair cable with 8P8C RJ45 modular plug.
Network Configuration
Fig. 3-1 Example of Connection
The length of the cable connecting this Switching Hub and a device must be 100 m or shorter.
When a terminal or a LAN device with auto negotiation function is connected to this Switching
Hub, the port is automatically configured at the highest performance mode. When a terminal
or a LAN device without auto negotiation function is connected to this Switching Hub, this Switching
Hub automatically determines and sets the communication speed; however, the
full-duplex/half-duplex configuration is set at half-duplex because the full-duplex/half-duplex
capability cannot be determined. When connecting a terminal or a LAN device without auto
negotiation function, a fixed-mode port configuration needs to be set.
Note: If a fixed-ode port configuration is set, Auto-MDI/MDI-X function does not work. Therefore,
use a cross cable to connect them.

Plugging an SFP module (optional) into an SFP extension slot enables an optical fiber connection.
Connect this Switching Hub's TX port to the RX port of the connected device and this Switching
Hub's RX port to the TX port of the connected device.
If a twisted pair cable and an SFP module are simultaneously connected to combo ports that
are used exclusively, SFP link has a priority.

Connect the supplied power code to the power port of this Switching Hub and connect the
other end into an electric outlet. This Switching Hub operates at 100-240 V (50/60 Hz).
This Switching Hub does not have a power ON/OFF switch. Plugging the power cord turns
on this Switching Hub's power and the operation starts. To power off, unplug the power code
from the electric outlet.

4. Configuration
Upon power on, this Switching Hub starts working as a switching hub. To use the SNMP
management functionality or other unique functions, you need to configure the Switching Hub
using a console port, Telnet, or SSH.
In this chapter, the configuration of this Switching Hub is explained.
Note: You need to configure an IP address to access this Switching Hub via Telnet or SSH.
Therefore, configure an IP address first via the console port, before accessing via Telnet
or SSH.

Console connection requires a DEC VT100-compatible asynchronous terminal, or a terminal
capable of running a VT100-compatible terminal emulator, such as HyperTerminal on Windows
XP or older. Connect a terminal of this kind to the console port of this Switching Hub.
Configure the communication mode for the asynchronous terminal as follows:
Transmission mode: RS-232C (ITU-TS V.24 compatible)
Emulation mode: VT100
Transmission speed: 9600 bps
Data length: 8 bit
Stop bit: 1 bit
Parity control: None
Flow control: None
If you are using a Windows machine before Windows XP, refer to "Appendix B. Procedures
for Console Port Connection using Windows HyperTerminal."
