Product Outline
Switch-M48eG is an Ethernet Switching Hub with management function having 44 ports
of 10/100/1000BASE-T and 4 pairs 10/100/1000BASE-T ports and SFP extension slot,
one of which is selectable.
1.1 Features

Has wire-speed Layer 2 switching function.
Has a loop detection function, which notifies when a loop occurs with the
corresponding port LED and automatically shuts down the looped port.
In addition, when a port is shut down and when it automatically recovers, an SNMP
trap can be sent to notify the administrator.
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.
Embedded power saving mode detects the connection status automatically and
saves power consumption to minimum.
Use of LED indicator switching button saves power consumption of LED lamps.
Ports 1 to 48 are auto negotiation-ready 10/100/1000BASE-T ports. Their speed and
communication mode can be changed by configuration.
Ports 45-48 can be used as a 10/100/1000BASE-T port corresponding to auto
negotiation or an SFP extension slot exclusively.
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 44 are set at MDI-X. (default))
VLAN function allows free grouping of up to 256 VLANs.
The IEEE802.1p compatible QoS function is supported.
Has an Internet Mansion function, which ensures security between each door.
Has a port grouping function, which groups ports that are allowed to communicate
with one another to limit communications between different groups.
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.
The IEEE802.1X compatible user authentication function (EAP-MD5/TLS/PEAP) is
supported.
