The following figure shows the screen layout that appears when an administrative user clicks the Software Upgrade tab under Access Æ IPDU.A table similar to the one in the screen shown in IPDU “Software Upgrade” Screen displays information about any directly-connected AlterPath PM IPDU, which is called the “Master Unit,” and about any daisy-chained IPDUs, which are named “Slave 1” through “Slave N.” Each entry displays the version number of the software that is currently installed on the IPDU. The “Refresh” button also appears on the screen.IPDU “Software Upgrade” Screen shows entries for a Master Unit that has software version 1.6.0 and a Slave Unit 1 that has software version 1.7.1.Note: Daisy-chaining only works if all daisy-chained IPDUs are running the same version of the PM software. The OnBoard administrator must ensure that all connected AlterPath PM IPDUs have the most recent version of the PM software.Clicking “Refresh” has effects shown in Upgrade Button on the IPDU “Software Upgrade” Screen, but only if both the following are true:
• A /tmp/pmfirmware file exists on the OnBoard
• The file contains a more recent version of the PM software than the one currently installed:As shown in Upgrade Button on the IPDU “Software Upgrade” Screen, the following appear on the screen if the two prerequisites in the previous list are true:
• The “Latest software version available” value changes to match the version in /tmp/pmfirmware.Pressing the “Upgrade” button starts the upgrade process. The top of the screen shown in the following figure shows the message that displays when the selected AlterPath PM IPDU is being upgraded, and the remaining text in the screen displays when upgrading is complete.Pressing OK on the dialog shown in IPDU Software Upgrade Dialog brings up the “Software Upgrade” screen, which displays the new software version for the selected IPDU.The following table lists the tasks for upgrading software on a connected AlterPath PM IPDU and where they are documented
Download an updated version of the AlterPath PM software from Cyclades and install the software in the /tmp/pmfirmware directory, To Download AlterPath PM IPDU Software From CycladesAn administrative user can use this procedure to download AlterPath PM software from the Cyclades ftp server.Note: Updated versions of related documents can also be found on the Cyclades website under Support Downloads/Documentation.After downloading the software onto the OnBoard by following this procedure, the administrative user needs to perform the procedure under To Upgrade Software on a Connected IPDU to update the software on connected AlterPath PM IPDU(s).
2. Change to the /tmp directory into which the software needs to be downloaded.
[admin@OnBoard admin]# cd /tmp
3.
[admin@OnBoard tmp]# ftp ftp.cyclades.com
4. Enter “anonymous” when prompted for the “Name” and press “Enter” when prompted for the password.
5. Change directories to /pub/cyclades/alterpath/pm/released and list the directories it contains.As shown in the previous screen example, the directories are named for the software release numbers. The latest version in the example is V_1.8.0. If the latest version at the Cyclades site is more recent that the version installed on the IPDU, continue with this procedure to download the latest version.As shown in the previous screen example, the directory contains a binary file (PM_version_number.BIN) for the latest software version, a checksum file (PM_version_number.md5sum), and a doc directory, which contains PDFs of the latest AlterPath PM documentation.
7. Use the get command to get the binary file (for example: PM_180.BIN) and enter pmfirmware as the destination filename
ftp> get PM_180.BIN pmfirmware
8. After the download completes, end the ftp connection, and verify the presence of the pmfirmware file in the /tmp directory.
• A more-recent version of the AlterPath PM software than the one shown on the “Software Upgrade” form on the OnBoard must be available from Cyclades, Corp.
• The more-recent version of the AlterPath PM software has been downloaded and copied into the OnBoard’s /tmp directory with the filename pmfirmware. For the procedure, see To Download AlterPath PM IPDU Software From Cyclades.
2. Go to Access Æ IPDU Æ Software Upgrade.If a /tmp/pmfirmware file exists containing a more recent version of the PM software than the one currently installed, the following changes occur on the screen:
• The value next to “Latest software version available:” changes to match the version in /tmp/pmfirmware.
