i. Error Type 1538 indicates a hyperactive EI circuit pack that is generating an abnormal 

amount of control messages to the Processor. When this error was generated, the EI was 
automatically reset by the system. If this system does not have duplicated Port Network 
Connectivity, service to the PN will have been disrupted. If this system does have duplicated 
Port Network Connectivity, the system should have switched to the standby Port Network 
Connectivity.

1. Enter reset board location for this EI circuit pack.
2. If error 1538 is detected again, replace the EI circuit pack.

j. Error Type 2049 with Aux Data 117 indicates that there is a problem with the fiber optic 

interface (FOI), that is generating bit errors. Sometimes these bit errors may be constant. 
This error could be caused by a crimped fiber, a fiber that is not seated correctly in the 
transceiver, or a defective transceiver.

k. Error Type 2305 with Aux Data 118 indicates that the EI circuit pack has detected slips on 

the incoming fiber data stream. That is, a PN in a Direct Connect configuration, or a PN and 
a Switch Node in a Center Stage Switch configuration, are not synchronized.

1. Enter display errors and follow the repair procedures for non-slip errors against any 

SYNC, TDM-CLK, TONE-BD, DS1C-BD, EXP-INTF, SNC-BD, and SNI-BD. Non-slip 
errors are those not listed below:

2. For slip errors, see 

l. Error Type 2306 indicates on-board failures related to system timing and synchronization. 

Perform the 

 described in 

 of 

Maintenance Procedures (03-300192).

m. Error Type 2561 indicates an on-board failure of EI circuitry related to handling packet data 

from the fiber interface and from the packet-bus interface.

1. If this error has generated a minor alarm, the EI circuit pack should be replaced.

n. Error Type 2817 indicates an on-board failure of EI circuitry related to transmission of data 

to the fiber interface.

1. If this error has generated a minor alarm, the EI circuit pack or transceiver should be 

replaced.
