Table 15 Troubleshooting the switch (continued)
Issue
LEDs on one or more
components are changing
rapidly or do not indicate a
healthy state.
None of the LEDs on an
individual component are
on.
84 Operating the switch
Possible cause
The switch might be booting or
running POST.
Beaconing might be on for the
entire switch or for individual
components.
Individual components might have
failed.
Pins on the components might be
damaged.
Component might not be seated
correctly.
Component might have failed.
Recommended action
Verify that boot and POST are
complete. The switch requires a
minimum of 3 minutes, usually,
after power-on to complete POST.
Determine whether beaconing is
on by entering the switchShow
command and determine whether
switch beaconing or blade
beaconing are on.
Refer to the LED tables in
"Interpreting LED activity" on
page 64 for recommended
actions.
Remove component from chassis
and inspect pins on component
and inside chassis. Do not reinstall
if pins on either component are
visibly damaged, as this could
damage pins on other component.
Replace parts as required.
Ensure that the switch has power
and component is firmly seated. If
problem continues, run the
sensorShow command to
determine component status. If
component is a CP card or port
card, enter the slotShow
command to determine status.
Replace component as necessary.
