Troubleshooting the Brocade DCX 8510-4 (Continued) TABLE 28
Issue Possible cause Recommended action
LEDs on one or more
components are changing
rapidly or do not indicate a
healthy state. The Brocade DCX 8510-4
might be booting or
running POST. Verify that boot and POST are complete. The
Brocade DCX 8510-4 requires a minimum of 3
minutes, usually, after power-on to complete POST.
Beaconing might be on for
the entire Brocade DCX
8510-4 or for individual
components. Determine whether beaconing is on by typing the
switchShow command and determine whether
switch beaconing or blade beaconing are on.
Individual components
might have failed. Refer to the LED tables in Monitor System
Components for interpretation and recommended
actions.
Pins on the components
might be damaged. Remove the component from the chassis and
inspect the pins on the component and inside the
chassis. Do not reinstall if pins on either component
are damaged, as this could damage pins on other
components. Replace the parts as required.
None of the LEDs on a
component are on. Component might not be
seated correctly. Ensure that the Brocade DCX 8510-4 has power
and the component is firmly seated. If the problem
continues, enter the sensorShow command to
determine the component status. If the component is
a CP blade or port blade, enter the slotShow
command to determine the status.
Component might have
failed. Replace the component as necessary.
CP blades are failing over
frequently. There is excessive serial
port activity. Ensure that the serial port activity remains below
specified amount.
CP blade is attached to an
Ethernet with high traffic
loads. Ensure that the Ethernet traffic remains below
specified amount
Chassis is overheated. Enter the tempshow and sensorShow commands
to check internal temperature. If components are
overheating, shut down port blades as necessary to
return the temperature to operating range. Also try
moving the blades in the chassis because it is
possible that airflow might not be adequate to cool
everything in certain configurations.
One or more port blades have
either shut down or failed
POST as indicated by the
error log. Blades might be
overheated. Enter the sensorShow command to check the
internal temperature readings. If components are
overheating, shut down port blades as necessary to
return the temperature readings to the operating
ranges. Also try moving the blades in the chassis
because it is possible that airflow might not be
adequate to cool everything in certain
configurations.
