Description

This Major Alarm may be seen for the following DPCE (Dense Port Concentrator - Enhanced) model type installed in MX routers: 

FPC 0   REV 27   750-020452   AA1111  DPCE 40x 1GE X EQ
Also known as: 
ID: DPCE 40x 1GE X EQ   FRU Model Number:  DPCE-X-Q-40GE-SFP

Symptoms

During network operations, the DPCE 40x 1GE X EQ FPC may encounter a Major alarm "I Chip Error code: 0x150010".

An example is below: 

May 25 14:30:56  send: red alarm clear, device FPC 0, reason FPC 0 Major Errors - I Chip Error code: 0x150010
May 25 14:30:58  send: red alarm set, device FPC 0, reason FPC 0 Major Errors - I Chip Error code: 0x150010
May 25 14:30:58  send: red alarm clear, device FPC 0, reason FPC 0 Major Errors - I Chip Error code: 0x150010
........
May 25 15:44:11  send: red alarm clear, device FPC 0, reason FPC 0 Major Errors - I Chip Error code: 0x150010
May 25 15:44:13  send: red alarm set, device FPC 0, reason FPC 0 Major Errors - I Chip Error code: 0x150010

Note that the alarm is in a clear - set - clear pattern.


 

Solution

The error code is a transient ECC/CRC (error checking and correction / cyclic redundancy check) process error that goes into a set, clear, and set pattern. Log messages like the following may be seen: 

May 29 09:04:40  mx960 fpc0 ICHIP(0): multiple uncorrectable ECC errors, count 65535
May 29 09:04:42  mx960 fpc0 ICHIP(0): multiple uncorrectable ECC errors, count 65535
May 29 09:04:44  mx960 fpc0 ICHIP(0): multiple correctable ECC errors, count 65535
May 29 09:04:45  mx960 fpc0 ICHIP(0): multiple uncorrectable ECC errors, count 65535
May 29 09:04:47  mx960 fpc0 ICHIP(0): multiple uncorrectable ECC errors, count 65535
May 29 09:04:49  mx960 fpc0 ICHIP(0): multiple uncorrectable ECC errors, count 65535
May 29 09:04:07  mx960 fpc0 Cmerror Op Set: I Chip: ICHIP(0) ICHIP packet crc error at IP/LSIF interface  
May 29 09:04:09  mx960 fpc0 Cmerror Op Set: I Chip: ICHIP(0) ICHIP packet crc error at IP/LSIF interface  
May 29 09:04:11  mx960 fpc0 Cmerror Op Set: I Chip: ICHIP(0) ICHIP packet crc error at IP/LSIF interface

Recommendations:
  1. A reboot of the FPC (Flexible PIC Concentrator) in a maintenance window should clear this transient error.
  2. If the error recurs, please contact support for additional assistance.
