NOTE: Fans driven to a high RPM in dense air cannot maintain expected RPM and will be considered bad by the MP leading to a "False Fan Failure" condition. Power Control If active, the manageability firmware is responsible for monitoring the power switch on the front panel. Setting this switch to the ON position is a signal to the MP to turn on 48 V DC power to the server. The PE command can also be used to send this signal. This signal does not always generate a transition to the powered state. The following conditions prevent the manageability firmware from applying 48 V DC power to the server: • Insufficient number of active bulk power supplies • Insufficient number of I/O fans • Insufficient number of main fans • Ambient temperature is in an OVERTEMP HIGH condition Unless one of the following conditions occurs, 48 V DC power to the server is maintained: • A main fan failure causes there to be an insufficient number of main fans. • A I/O fan failure causes there to be an insufficient number of I/O fans. • Ambient temperature reaches an OVERTEMP HIGH condition. • The front panel power switch is turned OFF. • The PE command is issued to the manageability firmware to turn off power to the server cabinet. Firmware Updating The server MP pulls a firmware update from an FTP server over the management LAN.

NOTE:
Fans driven to a high RPM in dense air cannot maintain expected RPM and will be
considered bad by the MP leading to a “False Fan Failure” condition.
Power Control
If active, the manageability firmware is responsible for monitoring the power switch on the front
panel. Setting this switch to the ON position is a signal to the MP to turn on 48 V DC power to
the server. The
PE
command can also be used to send this signal. This signal does not always
generate a transition to the powered state. The following conditions prevent the manageability
firmware from applying 48 V DC power to the server:
•
Insufficient number of active bulk power supplies
•
Insufficient number of I/O fans
•
Insufficient number of main fans
•
Ambient temperature is in an OVERTEMP HIGH condition
Unless one of the following conditions occurs, 48 V DC power to the server is maintained:
•
A main fan failure causes there to be an insufficient number of main fans.
•
A I/O fan failure causes there to be an insufficient number of I/O fans.
•
Ambient temperature reaches an OVERTEMP HIGH condition.
•
The front panel power switch is turned OFF.
•
The
PE
command is issued to the manageability firmware to turn off power to the server
cabinet.
Firmware Updating
The server MP pulls a firmware update from an FTP server over the management LAN.
Instructions
•
The user logs in to the server console through the LAN, local serial, or remote serial locations.
•
The user types the
FW
command to start the firmware update.
NOTE:
The LAN configuration for the server must be set for the FTP connection to function
correctly regardless of whether the console LAN, local serial, or other connection is used to issue
the FW command.
FW – Firmware Update
•
Access Level: Administrator
•
Scope: Complex
•
Description: This command prompts the user for the location of the firmware software and
the FLASH handle (from a list) which represents all upgradeable entities.
DFW – Duplicate Firmware
•
Access Level: Administrator
•
Scope: Complex
•
Description: This command allows field support personnel to copy firmware already installed
on the system to an equivalent entity in the same complex.
Figure 5-11
illustrates the output and questions requiring responses. After the user replies
Y
to
the confirmation request, the firmware update makes the connection to the FTP server at the IP
address given using the user and password details supplied. The appropriate files will be
downloaded and burned into the selected flash memories. Note that the firmware update validates
the image to determine that the image name supplied is that of a valid image type before burning
the image into the flash memory.
