Error Log Entries and Test to Clear Values
Notes:
a. This alarm is used only to indicate that all Expansion Interface Links
between a pair of Port Networks (PNs) are down. This condition is
indicated by the EXP-LINK Error Type 122 in the Error Log. When this
condition occurs, examine all EXP-INTF errors to resolve the alarm.
The pair of PNs is specified in the port fields as follows: 1-2 (PPN to
EPN1), 1-3 (PPN to EPN2), and 2-3 (EPN1 to EPN2).
b. Aux Data values of blank and 1 through 10 mean that the link is down due
to a defective Expansion Interface Link. Look for and resolve Expansion
Interface circuit pack errors.
c. Aux Data values of 30 through 40 mean that the EPN was reset because of
a temporary loss of system timing reference on the EPN. Execute the
display errors command with the category “tone” to determine what
caused the loss or restoration of the clock.
