Replace a Route Processor Card
The router supports up to two redundant Route Processor (RP) cards. When two RP cards are installed in the
router, one acts as an active card and the other as the standby card. If the router has only one RP card installed,
a new RP can be installed in the empty RP slot during operation.
Note
The images in this chapter are only for representation purposes, unless specified otherwise. The chassis' actual
appearance and size may vary.
Whenever you replace any card, you must always ensure to secure the ejector thumbscrews properly.

• The replacement procedure for the RP cards is only applicable to the standby RP card. You need to
shutdown the router to replace an RP on a single-RP system. When you shutdown the standby RP card,
the router automatically shuts down the standby Switch Card (SC) as both of them belong to the same
operational domain. For example, when you shutdown RP0, the router shuts down the corresponding
SC0. When you shutdown RP1, the router shuts down SC1.
• To replace an active RP card, you must trigger a failover using the redundancy switchover command.

    Replace a Fan Module The Cisco 8608 router uses eight fan modules (8608-FAN) but it can operate with seven fan modules while you replace one. When you remove one fan module, the other fan modules speed up their fans to maintain the designed airflow.
  • Page 18 Replace Chassis Components Replace a Fan Module Note To ensure adequate airflow and prevent overheating, do not operate the router with seven fan modules for more than 10 minutes. If you cannot replace a fan module within three minutes, we recommend that you leave it in the chassis until you are ready to replace it.
