Table 8: LED problem indicators
Symptom
Green AC power supply
LEDs are off.
The Link/Activity LED for
a connected port is off or
does not blink (and you
believe that traffic is
present).
The Link/Activity LED
blinks continuously.
The Online LED is steady
amber for longer than 3
minutes.
The Master LED on a
module in slot 5 or slot 6 is
amber (8010, 8010co,
and 8006 chassis).
Troubleshooting
Probable cause
The switch is not receiving
AC power or the power
supply has failed.
The switch is
experiencing a port
connection problem, or
the link partner is not auto-
negotiating properly.
There may be a high
traffic load or possible
packet broadcast storm.
Software incompatibility
exists, or the module
cannot communicate with
the master module over
the backplane.
The module has detected
a system clock generation
failure on its own
circuitry.
Corrective action
Verify that each AC power cord is
fastened securely at both ends and
that power is available at each AC
power outlet. Plug in a device such
as a lamp to ensure that the power
outlet is operational. Verify that
each power supply is turned on.
Verify that the cable connections to
the link partner are correct. Verify
port configuration parameters for
both ends of the connection. Move
the cable to another port to see
whether the problem occurs on the
new port.
Verify port configuration
parameters for both ends of the
connection.
Use the show log command to
check the system log for indications
of communication problems. Use
the boot command to download a
new software image.
Replace the module; make sure
that it is in the correct slot.
