Installing SAN Director 2/128 FRUs Replacing a CP Card This section describes how to remove and replace a control processor (CP) card from the SAN Director 2/128. Each SAN Director 2/128 has two CP cards: one located in slot 5 and the other in slot 6. The SAN Director 2/128 can continue to operate while one CP card is replaced if the other CP card continues to operate and no failover occurs (you can prevent failover by entering the hadisable command). The active CP card is determined by the most recent failover. The configuration on the active CP card is automatically mirrored to the standby CP card; this section includes steps to ensure that the new CP card boots up as the standby CP card. The new CP card automatically assumes the IP address and host name assigned to the slot. If the new CP card does not have the same firmware as the active CP card, it must be upgraded or downgraded to the same firmware version. Note: Disassembling any part of a CP card voids the part warranty and regulatory certifications. There are no user-serviceable parts inside a CP card. To ensure adequate system pressure for cooling purposes, leave the faulty CP card in the slot until you are ready to perform the replacement procedure. Caution: Disassembling any part of a CP card voids the part warranty and regulatory certifications. There are no user-serviceable parts inside a CP card. To ensure adequate system pressure for cooling purposes, leave the faulty CP card in the slot until you are ready to perform the replacement procedure. Caution: Use the same version of Fabric OS on both CP cards. Using different versions can cause malfunctioning. If the replacement CP card has a different version, update cards to the same firmware version. SAN Director 2/128 Installation Guide 121
