• Input new line sequences
For more information about these properties, see the IPMI 2.0 
specification.
Using the IPMI Remote Access Serial Interface
In the IPMI serial interface, the following modes are available:
•IPMI terminal mode — Supports ASCII commands that are submitted 
from a serial terminal. The command set has a limited number of 
commands (including power control) and supports raw IPMI commands 
that are entered as hexadecimal ASCII characters.
•
IPMI basic mode — Supports a binary interface for program access, such 
as the IPMI shell (IPMISH) that is included with the Baseboard 
Management Utility (BMU).
To configure the IPMI mode using RACADM:
1
Disable the RAC serial interface.
At the command prompt, type:
racadm config -g cfgSerial -o 
cfgSerialConsoleEnable 0
2
Enable the appropriate IPMI mode.
For example, at the command prompt, type: 
racadm config -g cfgIpmiSerial -o 
cfgIpmiSerialConnectionMode

Recovering and Troubleshooting 
the Managed System
This section explains how to perform tasks related to recovering and 
troubleshooting a crashed remote system using the DRAC 5 Web-based interface.
• First Steps to Troubleshoot a Remote System on page 277
• Managing Power on a Remote System on page 277
• Using the System Event Log (SEL) on page 281
• Viewing the Last System Crash Screen on page 283
First Steps to Troubleshoot a Remote System
The following questions are commonly used to troubleshoot high-level 
problems in the managed system:
1
Is the system powered on or off?
2If powered on, is the operating system functioning, crashed, or just frozen?
3If powered off, did the power turn off unexpectedly?
For crashed systems, check the last crash screen (see Viewing the Last 
System Crash Screen on page 283), and use console redirection (see 
Supported Screen Resolutions Refresh Rates on the Managed System on 
page 162) and remote power management (see Managing Power on a 
Remote System on page 277) to restart the system and watch the reboot 
process.
Managing Power on a Remote System
The DRAC 5 enables you to remotely perform several power management 
actions on the managed system so you can recover after a system crash or 
other system event. 
Use the Power Management page to do the following:
• Perform an orderly shutdown through the operating system when 
rebooting, and power the system on or off.  
						

							278Recovering and Troubleshooting the Managed System
• View the system’s current Po w e r  S t a t u s—either ON or OFF.
To access the Po w e r  M a n a g e m e n t page from the System tree, click System 
and then click the Power Management tab.
 NOTE: You must have Execute Server Action Commands permission to perform 
power management actions. 
Selecting Power Control Actions from the DRAC 5 GUI
1Select one of the following Power Control Actions.
• Power On System— Turns on the system power (equivalent to 
pressing the power button when the system power is off). 
•
Power Off System— Turns off the system power (equivalent to 
pressing the power button when the system power is on). 
•
Reset System— Resets the system (equivalent to pressing the reset 
button); the power is not turned off by using this function. 
•
Power Cycle System— Power off, then reboot (cold boot) the system.
2Click Apply to perform the power management action (for example, cause 
the system to power cycle).
3Click the appropriate Po w e r  M a n a g e m e nt page button to continue 
(see
Table 16-1).
Selecting Power Control Actions from the DRAC 5 CLI
Use the racadm serveraction command to perform power 
management operations on the host system. 
racadm serveraction 
The options for the  string are:
•powerdown — Powers down the managed system.
•
powerup — Powers up the managed system.

							Recovering and Troubleshooting the Managed System279
•powercycle — Issues a power-cycle operation on the managed system. 
This action is similar to pressing the power button on the system’s front 
panel to power down and then power up the system.
•
powerstatus — Displays the current power status of the server (ON, or 
OFF)
•
hardreset — Performs a reset (reboot) operation on the managed system.
Viewing System Information
The System Summary page displays information about the following system 
components:
• Main System Chassis
