Introduction
Este documento descreve o problema e a solução relacionados aos erros de falha do ventilador relatados pelas interceptações SNMP (Simple Network Management Protocol), vistas na plataforma Cisco Aggregation Services Router (ASR) 5500. Isso normalmente acontece, ainda que raro, na operação normal da plataforma.
Problema
Em alguns casos, o alarme FanFailed é visto na plataforma ASR 5500 em relação aos números de ventilador 1 e 2, conforme mostrado aqui:
Tue Apr 01 16:07:07 2014 Internal trap notification 22 (FanFailed)
fan number 2 fan status Communication Error
Tue Apr 01 16:07:27 2014 Internal trap notification 22 (FanFailed)
fan number 1 fan status Communication Error
Os ventiladores traseiros e frontais inferiores reportam atualmente um estado Desconhecido e a temperatura geral das placas de nó parece estar OK no momento.

Solução
Esse problema geralmente é resolvido quando você recoloca os módulos do ventilador. Conclua estes passos para verificar se o status é normal:
- Deslize o módulo do ventilador para fora. Aguarde de dois a três minutos e depois deslize-o de volta no slot.
- Insira este comando para verificar se os ventiladores estão no estado normal:

- Insira este comando para verificar se os módulos do ventilador executam a versão correta do firmware:
[local]ASR5500# show hardware version fans

Fan Tray Controller Version
Upper Fan Tray: 0.2.5
Lower Fan Tray: 0.2.5
- Insira este comando para verificar se os erros de interceptação (trap) SNMP foram eliminados e se não há erros depois que o módulo do ventilador foi recolocado:
[local]ASR5500# show snmp trap hist ver | grep -i fan
