High Availability in a PE Stack A port extender (PE) stack has a master and standby management unit that provide redundancy in a similar way to redundant route processor modules (RPMs). If the master stack unit fails or is removed, the standby unit becomes the stack manager. The stack elects a new standby unit and resets the failed master unit. The failed master becomes online as a member unit; the remaining members remain online. For more information about the failover process in a PE stack, see the Port Extender (PE) Stacking chapter. Online Insertion and Removal You can add, replace, or remove chassis components (RPMs, line cards, fan modules, power supplies) while the switch is operating. C9010 RPMs and line cards are hot-swappable. Use the information in this section when inserting an RPM or line card in the C9010 chassis. For more information about how to install an RPM or line card in the C9010, see the C9010 Getting Started Guide or C9010 Installation Guide. RPM Online Insertion Dell Networking systems can function with only one RPM. If you insert a second RPM, it comes online as the standby RPM. To display the status of installed RPMs, enter the show rpm all command. Dell# show rpm all -- Route Processor Modules -- Slot Status NxtBoot Version 0 active online 1-0(0-4095) 1 standby online 1-0(0-4095) Line Card Online Insertion When you insert a line card into an online chassis, the Dell Networking OS detects the line card type. The system writes the line card type to the running configuration and maintains this information as a logical configuration if you remove the card. To display the status of installed line cards, enter the show linecard all command. Dell# show linecard all -- Linecard Info -- LinecardId Type Status ReqTyp CurTyp Version Ports 0 Linecard online C9000LC2410T C9000LC2410T 1-0(0-4095) 24 1 Linecard online C9000LC2410G C9000LC2410G 1-0(0-4095) 24 2 Linecard online C9000LC2410T C9000LC2410T 1-0(0-4095) 24 High Availability (HA) 469
