Chapter 3 LED Indicators
Figure 3-1 shows the LED indicators which indicate the link status of
each of the ports, whether the LFH hub is receiving power, and the
presence of network utilization % and partition on the network.
Figure 3-1 LFH16-S Front Panel LED Indicators
3.1 Power LED
The green LED on the front panel labeled
PWR
is used to indicate that
the LFH hub is receiving power and is turned on. If the LED is off,
check the following to isolate the problem:
▼
Make sure the power cord is properly connected to the power outlet
and is properly inserted into the power connection on the LFH hub
▼
Determine whether or not the outlet is functional by plugging
another device into the receptacle
3.2 Partition LED
The yellow Partition LED is located on the front panel and labeled as
Partition
. When there are too many collisions received from a specific
station(s), the hub will automatically partition it to prevent data trans-
mission to those specific ports. When this port is partitioned, the LED
will be turned on.
