abnormal network condition.
NO LIGHT OFF Port is in good condition.

The Partition LEDs are also used as diagnostic LEDs. Please refer
to the section on
Diagnostic
Test LED Indicators
later in this chapter
for more information.
Partition
A port is temporarily partitioned when a line error or too many
collisions are detected on the attached segment. While it is
automatically partitioned, the port continues to receive data
from the segment. However, data is not transmitted onto the
segment. When the problem is corrected or a valid data packet
is received through the port, the port is automatically recon-
nected. When partitioning occurs, the port’s corresponding
Partition LED will be continually lit (RED light). Otherwise,
this LED should be OFF (unlit).
Link/Traffic
LED Activity Condition Indication
STEADY GREEN LIGHT ON Indicates a valid link has been established on this
port.
BLINKING GREEN LIGHT ON Indicates the port is receiving packets; blinking is
proportional to the traffic passing through the port.
NO LIGHT OFF No valid link has been established on this port.
Link
The corresponding Link/Traffic LED should light up when a
device (e.g., computer, hub or bridge) establishes a valid
connection using the RJ-45 port. However, for the ALT port,
no link connection is tested. The Link/Traffic LED for ALT
only monitors the traffic condition.
