Select I/O Module Tasks → Admin/Power/Restart to view and manage the power status of the I/O modules.
The following illustration shows I/O module power and restart settings for an advanced management module.
Select Admin/Power/Restart to display the power status of the I/O modules and to perform the following actions:
- Turn on or turn off an I/O module
- Restart an I/O module
- Enable or disable protected mode for an I/O module that supports this feature. When protected mode is enabled for an I/O module, settings for that I/O module cannot be configured through the management module; all I/O-module configuration must be performed through the management interface that is provided by the I/O module. After you enable or disable protected mode through the management module, you must also enable or disable the feature through the I/O-module management console and restart the I/O module. The I/O module retains the protected-mode state that is set in the I/O-module management console, even if it is restarted or moved to a different BladeCenter unit. See the documentation for your I/O module for information.
Note: The BladeCenter S unit supports the RAID
serial-attached SCSI (SAS) module, a unit with two subsystems: a SAS switch
and a RAID controller. If this device is installed, the I/O Module Power/Restart
page is modified as follows:
- The MAC Address and IP Address columns shows the MAC addresses and IP addresses of both subsystems.
- The Pwr column supports a third status message, Shutdown in Progress. This state can occur when a power-off request is issued to the I/O module, which requires additional time to complete pending operations and perform an orderly shutdown. For example, a SAS controller module might need to flush pending I/O operations before it powers off to maintain data integrity.
- The ID column shows the VPD identifications of both subsystems.
- The SAS switch subsystem has one network interface card (NIC) that has a direct Ethernet connection to the advanced management module. The upper IP address label, which ends with "S," is that of the SAS switch subsystem.
- The RAID controller subsystem has one NIC and an indirect Ethernet connection to the advanced management module through the I/O module in bay 1. The lower ID label, which ends with "R," is that of the RAID controller subsystem.
For each I/O module, enable or disable the following features:
- Fast POST
- External ports
