Chapter 4 Troubleshooting the IGX
Troubleshooting an IGX Node
Displaying a Summary of Alarms
The first step in troubleshooting an IGX node is to check the condition of the system by displaying alarm
conditions throughout the system. To see a summary of all the alarms on an IGX node, use the dspalms
(display current node alarms) command. The alarms summary includes the following:
• Number of failed connections
• Number of major and minor alarms
• Number of failed cards
• Power monitor failures
• Bus failures (either failed or needing diagnostics)
• Number of alarms on other nodes in the network
• Number of unreachable nodes in the network
Note You cannot include the dspalms command in a job.
To display alarms, enter the dspalms command.
If the screen indicates a failure, refer to the commands in Table 4-1 to further isolate the fault.
Displaying the Status of Cards
When a card indicates a failed condition on the alarm summary screen, use the dspcds command to
display the status of the cards on a node. The information displayed for each card type includes the slot
number, software revision level, and card status. (Note that you cannot use dspcds in a job.)
Note If the dspcds command or any other command incorrectly states the IGX model (for example, stating
that an IGX 8420 node is an IGX 8430 node), check the jumper switch W6 on the SCM. A jumpered W6
indicates an IGX 8420 node. An open W6 indicates an IGX 8430 node. Chapter 4, “Installing the IGX,”
documents this aspect of the SCM.
Table 4-2 lists all possible dspcds command status descriptions for all card types, including CVM.
