1. Product Outline
Switch-M48eG is an all Giga bit Ethernet Switching Hub with management
function having 44 ports of 10/100/1000BASE-T and four pairs of
10/100/1000BASE-T port and SFP extension slot, one of which is selectable.
1.1. Features
Has wire-speed Layer 2 switching function.
Ports 1 to 44 are 10/100/1000BASE-T ports corresponding to auto
negotiation. Also their speed and communication mode can be switched
by configuration. Ports 45 to 48 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 44 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.
