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

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.

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.

------------------------------------------

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
