2.2 Guide to Trouble Indications
Table 2-1 provides a general troubleshooting guide. In many cases this
information will be sufficient to diagnose and correct a problem.
If an error not mentioned in the table has occurred, check the unit’s Fault Log
and refer to the Fault Conditions table (Table 2-1) in this document. In
addition, the unit automatically sends SNMP traps for a Network Management
System (NMS) giving notification of the fault. See Section 3 for details
regarding Trap Information.
