Using the AP LEDs to Determine the Problem
7-8
AP (Classic) LEDs
Tabl e 7- 6 describes the LED functio ns. Tabl e 7- 7 describes the patterns, likely causes, and
possible corrective actions. Table 7-8 describes the patterns during a firmware upgrade.
Table 7-6: AP (Classic) LEDS
Name Description
Power OK Lights (green) when the AP has power.
Module OK Lights (green) when the AP passes its power-up self-test. The LED is off if
the AP fails the test. If flashing, the Ethernet or wireless port (or both) has a
fault, preventing connection to the network.
Wired LAN Activity Indicates the status of the wired Ethernet segment. The LED lights (green)
when packets are:
•Received on the Ethernet port and forwarded to the wireless port.
•Addressed to or generated by the AP using the Ethernet port.
Packets received and filtered are not shown. Data traffic forwarded to the
Ethernet port is not shown. The average brightness of the LED ind icates the
level of activity on the Ethernet port. If the LED is flashing together with the
Bridge State LED, the Ethernet port has a fault that prevents the AP from
establishing a connection to the network.
Bridge State Lights (green) when the AP is forwarding packets.
AP Saturated Lights (yellow) when the AP is saturated. Saturation occurs when the AP
cannot forward packets from the Ethernet to the wireless side due to the
lower throughput of the wireless network. The d egree of LED brightness
indicates the level of saturation. The LED dims (and eventually
extinguishes) as the network congestion is processed.
Wireless LAN
Activity The LED lights (green) when packets are:
•Received on the wireless port and forwarded to the Ethernet port.
•Addressed to or generated by the AP using the wireless port.
Packets received and filtered are not shown. Data traffic forwarded to the
wireless port is not shown. The average brightness of the LED indicate s the
level of activity on the wireless port. If the LED is flashing together with the
Bridge State LED, the wireless port has a fault that prevents the AP from
establishing a connection to the network.
Card Present Lights (green) when the PC Card is correctly installed at power-up.
