Troubleshooting
TABLE 18 Troubleshooting the Brocade DCX (continued)
Issue
CP Ethernet link speed is different than expected
or a link cannot be established.
Configuration data is inaccurate or cannot be
accessed.
Initial set up results in IP address/Domain ID
conflict.
LEDs on one or more components are changing
rapidly or do not indicate a healthy state.
None of the LEDs on a component are on.
CP blades are failing over frequently.
146
Possible cause
Pins on the serial cable or serial port might be
damaged.
There might be a conflict with the CP Ethernet
link speed negotiation set up by the network.
Chassis was powered off/on while a WWN card
was uninstalled or failed.
The Brocade DCX was rebooted while a WWN
card was uninstalled or failed.
The Brocade DCX was connected to the fabric
before being configured.
The Brocade DCX might be booting or running
POST.
Beaconing might be on for the entire Brocade
DCX 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.
A third-party application has a memory leak.
There is excessive serial port activity.
CP blade is attached to an Ethernet with high
traffic loads.
Chassis is overheated.
Recommended action
Remove the cable and inspect the pins on the
cable and in the serial port. Do not reinstall if the
pins on either component have any visible
damage, as this could damage the pins on the
other component. Replace the components as
required.
Specify the CP Ethernet link speed by entering
the ifModeSet command.
For more information about Ethernet
connectivity to the Brocade DCX, refer to the
LAN guidelines provided through the
MyBrocade Web site.
Install an operational WWN card and power the
system off/on again.
See Logging In and Configuring the DCX
Backbone on page 51 and the Brocade Fabric
OS Administration Guide for configuration
information.
Verify that boot and POST are complete. The
Brocade DCX 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 is
on.
See the LED tables in Monitoring System
Components on page 63 for interpretation and
recommended actions.
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.
Ensure that the Brocade DCX 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.
Replace the component as necessary.
Check application for memory leaks.
Ensure that the serial port activity remains below
specified amount.
Ensure that the Ethernet traffic remains below
specified amount
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.
