LED Indicators
The front panel of the IMC-101G has several LED indicators. The function
of each LED is described in the table below.
LED Color State
Description
PWR1 Amber
On Power is being supplied to power input PWR1
Off Power is not being supplied to power input PWR1
PWR2 Amber
On Power is being supplied to power input PWR2
Off Power is not being supplied to power input PWR2
FAUL
T
Red
On
When the corresponding PORT alarm is enabled
and the port’s link is inactive.
Off
When the corresponding PORT alarm is enabled
and the port’s link is active, or when the
corresponding PORT alarm is disabled.
G2 Green
On SFP port’s 1000 Mbps link is active.
Blinking Data is being transmitted at 1000 Mbps.
Off SFP port’s 1000 Mbps link is inactive.
G1 Green

Off TP port’s 1000 Mbps link is inactive
10M Green
On TP port’s 10 Mbps link is active
Blinking Data is being transmitted at 10 Mbps
Off TP port’s 10 Mbps link is inactive
100M Green
On TP port’s 100 Mbps link is active
Blinking Data is being transmitted at 100 Mbps
Off TP port’s 100 Mbps link is inactive
Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the IMC-101G’s
10/100/1000BaseT(X) ports to any kind of Ethernet device, without
paying attention to the type of Ethernet cable being used for the
connection. This means that you can use either a straight-through cable
or crossover cable to connect the IMC-101G to Ethernet devices.
Dual-Speed Functionality and Switching
The IMC-101G’s 10/100/1000 Mbps RJ45 switched port auto negotiates
with the connected device for the fastest data transmission rate
supported by both devices. All models of the IMC-101G are plug-and-play
devices, so that software configuration is not required at installation, or
during maintenance. The half-duplex or full-duplex mode for the RJ45
switched ports is user dependent and changes (by auto-negotiation) to
full-duplex or half-duplex, depending on which transmission speed is
supported by the attached device.
Auto-Negotiation and Speed Sensing
All of the IMC-101G’s RJ45 Ethernet ports independently support
auto-negotiation for transmission speeds of 10 Mbps, 100 Mbps , and
1000 Mbps, with operation according to the IEEE 802.3u standard.
This means that some nodes could be operating at 10 Mbps, while at the
same time, other nodes are operating at 100 Mbps or 1000 Mbps.
