Reloading, Shutting Down, or Power Cycling a Node

Communicating with a Standby RP

The primary RP automatically synchronizes all system software, settings, and configurations with the
standby RP. Under normal operating conditions, users communicate only with the active primary RP, as
indicated in the CLI prompt. Users do not communicate directly with the standby RP.
It is possible to connect a terminal directly to the Console port of the standby RP to place the card in
ROM monitor bootstrap mode or to load software directly to the standby RP. For more information on
these techniques, refer to
Cisco IOS XR Software Packages."
Reloading, Shutting Down, or Power Cycling a Node
Use the commands described in this section to reload the Cisco IOS XR software on the primary RP or
on any specified node in the system. This section also describes the commands used to administratively
shut down a node, and to power a node on or off.

summarizes the commands described in this section.
Description
Administratively turns the power on for a node. The changes do not take effect until
you enter the commit command.
To power off a node, use the no form of this command.
Note This command cannot be used on the RPs.
Reloads the Cisco IOS XR software on a specific node. The node reloads with the
current running configuration and active software set for that node.
Administratively shuts down a specified node. Nodes that are shut down still have
power, but cannot load or operate Cisco IOS XR software.
To return a node to the up state, use the no form of this command.
This command cannot be used on the RPs.
Note
Causes the primary RP to reload the Cisco IOS XR software according to the
configuration register setting (for example, 0x0 to enter ROMMON bootstrap mode,
0x2 to reload the RP to EXEC mode). See the
page 7-23 for more information.
Displays the configuration register setting for the router. The configuration register
setting determines how the router boots during a system reset. The most common
configuration register settings are:
0x2: The primary RP loads the Cisco IOS XR software and default configuration
•
on the next system boot. After logging in, the user can access EXEC mode.
0x0: The primary RP enters the bootstrap ROM monitor (
•
next system boot.
