The RMC or eRMC connects to all the system chassis through aphysically secure private LAN. The RMC is a standalone 1U rack-mounted Rack Management Controller (eRMC)The eRMC is an option for one and two chassis systems.

8 It provides RMC functionality using an existing BMCmanagement processor instead of a separate 1U Management Controller (BMC)Chassis-level management. Configures and manages the hardware in that chassis as well as providing virtual mediaand virtual keyboard, video, or mouse (KVM) manageability software includes: HPE OneView HPE Insight Remote Support HPE Serviceguard for Linux Smart Update ManagerFor an overview of management features, see Superdome Flex Server manageability features8 Rack management controller (RMC) tasksThe RMC includes a command set that you can use to perform administrative functions on the HPE Superdome FlexServer. This chapter shows how to complete several typical to the Rack Management Controller (RMC)You can connect to the RMC one of the following ways: Through a laptop attached to the connection is a direct-attached serial connection using the USB-A to Micro-USB-B cable that was included in theshipping example, this type of connection can be useful if you lost the RMC password.

9 With this kind of connection, the RMCdoes not prompt you for a password. For this reason, Hewlett Packard Enterprise recommends that you restrictphysical access to the system as part of your site security information about connecting to the RMC using a laptop, see HPE Superdome Flex Server User Guide . Through a network connection, through secure following procedure explains how to connect to the RMC over a network connection. See HPE Superdome FlexServer User Guide for information about setting networking parameters on the the secure shell (ssh) command to log into the factory configures the default login for the RMC to be to the prompts for the login name and ssh administrator@flex_rmcpassword: #####HPE Superdome RMC, Rev.
