Page 3-3
Port LEDs When the IntraSwitch is first powered on, the port and
diagnostic LEDs blink. The green power light illuminates and
remains on, indicating electrical power to the unit.
The IntraSwitch 5212 has five rows of LEDs. The following
table states their color and meaning:

LED Color Meaning
10/100TX port or an installed Asanté MII expansion
port is operating at 100Mbps speed.
Note: These LEDs only function with ports capable of
operating at 100Mbps speed (i.e., the 10/100TX port or
an installed 10/100 Asanté MII module).
The corresponding port’s receive buffer is full
(maximum utilization).
Note: It is normal to see these LEDs light when the
network is in a state of moderate-to-heavy activity.
Indicates full duplex mode on the 10/100TX port or on
an installed Asanté MII expansion port.
Indicates a collision at the switching port for those
ports operating in half-duplex mode.
Note: Full duplex means that a port can transmit and
receive at the same time.
Note: Collision is indicated only on those ports
operating in half duplex mode.
Traffic activity is occurring on the port (transmit [TX]
or receive [RX]).
Note:
During heavy traffic periods, this LED may be lit
continuously.
A node or other network device is properly connected
to the corresponding port.
