Downloading When One Controller Module Installed:
In an 8265 containing only one installed controller module, the system recognizes the single installed
controller module as the active controller module.
When you download software when there is just one controller module installed, keep in mind the
following:
Ÿ Power management functionality is inactive while a download is in progress, and until the download
completes.
Ÿ If a power failure occurs while download is in progress, the system may not be able to recover and the
controller module to which you are downloading may fail.
– Upon power recovery, replace the failed controller module and re-initiate the download to the
replacement controller module.
– Next (optionally), reinsert the original controller module (the one that failed during the first
download) and re-initiate download to the original controller module while the active controller
module is present and functioning.
The original controller module powers up as the standby controller module.
Upgrading Controller Module Boot Microcode
To upgrade the controller module boot microcode, enter the following commands:
1. SET TFTP SERVER_IP_ADDRESS (to define the server where the microcode is stored)
2. SET TFTP FILE_NAME (to define the path name of the file on the server)
3. SET TFTP FILE_TYPE CONTROLLER_BOOT (to specify boot microcode)
4. DOWNLOAD INBAND (to load the microcode).
Upgrading Controller Module Operational Microcode
To upgrade the controller module operational microcode, enter the following commands:
1. SET TFTP SERVER_IP_ADDRESS (to define the server where the microcode is stored)
2. SET TFTP FILE_NAME (to define the path name of the file on the server)
3. SET TFTP FILE_TYPE CONTROLLER_OPERATION (to specify operational microcode)
4. DOWNLOAD INBAND (to load the microcode).
Download Status Display
As you perform a download to the controller module, the controller module front panel indicates download
status.
Ÿ
The TEMP LED lights and remains lit until the download completes. If a download attempt is
unsuccessful, the STBY and ACTIVE LEDs on the controller module light and remain lit until you
re-initiate the download.
