The boot code and a switch operating system. The GbE switch module ships with this firmware pre-installed. However, new versions of the firmware are periodically released and can be used to update the features and function of the switch. 3.1 Software update procedure ----------------------------- Update the switch software using a TFTP or FTP server application. Typically, this application is installed on a machine that is reachable from the switch through the external ports or the management module. NOTES: - The following steps reflect the use of a TFTP server. A FTP server can also be used. - Upgrades can also be performed using external ports. Please see "Externally managing the GbE switch module" in the GbESM Installation Guide. 1) Download the GbESM software package (zip file) to the machine where the TFTP server resides. 2) Extract the Boot and OS image files into a directory. Enable the server and set its default directory to the one where the image files reside. 3) Establish a connection between the ethernet port of the BladeCenter Management Module and the TFTP Server. 4) Using the Management Module web interface (GUI), configure the IP Addr/Mask of the Management Module External (eth0) and Internal (eth1) interfaces, the GbESM switch and the TFTP server so that they all reside on the same subnet. For example, Management Module (eth0) => 192.168.70.125 / 255.255.255.0 Management Module (eth1) => 192.168.70.126 / 255.255.255.0 GbESM Current IP Config => 192.168.70.127 / 255.255.255.0 TFTP Server => 192.168.70.254 / 255.255.255.0 NOTE: Although configured as such, for this example, the TFTP Server does not have to be on the same subnet as long as a proper gateway address is configured in the switch. 3.1.1 Using Telnet ------------------ 1) Using the Management Module GUI, navigate to: I/O Module Tasks -> Management -> Bay X -> Advanced Management -> Start Telnet session When the telnet session is established, you will begin using the Command Line Interface (CLI) of the GbE switch. 2) Enter "admin" for the password. The GbE switch provides storage for two (2) OS images and one (1) Boot image. What you are about to do consists of the following sequence: - load the new OS image into one of the image banks - reset the switch - load the Boot image - reset the switch NOTE: When you reset the switch it boots using the 'selected' image (1 or 2). Please ensure that you are booting from the upgraded image (execute /boot/cur to determine). 3) Upgrade the OS image by entering the following commands: a) /boot/gtimg X TADDR GbESM-AOS-21.0.1.1-os.img WHERE: ------ X => 1 or 2 (depends which image bank you want to use) TADDR => IP Address of the TFTP Server NOTE: It is recommended that you retain the previous OS version by loading the upgrade into the other image bank and then reset the switch using the new image. (use /boot/image command to select preferred image) Answer 'Y' to the confirmation question, then wait for the upgrade to complete successfully. b) /boot/reset NOTE: You MUST Reset the switch to activate the new image. Resetting the switch kicks you out of the CLI, so Steps 1 and 2 need to be executed again before proceeding to the next step. A switch reset completes in approximately 60 seconds. 4) Upgrade the Boot image by entering the following commands: a) /boot/gtimg boot TADDR GbESM-AOS-21.0.1.1-boot.img Answer 'Y' to the confirmation question, then wait for the upgrade to complete successfully. b) /boot/reset 3.1.2 Using BBI --------------- 1) Using the Management Module GUI, navigate to: I/O Module Tasks -> Management -> Bay X -> Advanced Management -> Start Web session 2) Enter "admin" for the username and 'admin' for the password. 3) Click the CONFIGURE button (near top of page) 4) In the frame on the left, click on the "Nortel Networks Layer 2-7 GbE" folder icon and navigate to: System -> Config/Image Control The GbE switch provides storage for two (2) OS images and one (1) Boot image. What you are about to do consists of the following sequence: - load the new OS image into one of the image banks - reset the switch - load the Boot image - reset the switch NOTE: When you reset the switch it boots using the 'selected' image (1 or 2). Please ensure that you are booting from the upgraded image (see "Next Boot Image Selection" field). 5) Upgrade the OS image as follows: a) Fill in the following three (3) fields on the lower half of the page: Hostname or IP Address of FTP/TFTP server => Image Filename => GbESM-AOS-21.0.1.1-os.img Image for Transfer => 1 or 2 (i.e. the preferred image bank) NOTE: It is recommended that you retain the previous OS version by loading the upgrade into the other image bank and then reset the switch using the new image. (use the "Next Boot Image Selection" field to select the preferred image). b) Click the "Get Image" button. Wait for the upgrade to complete successfully. c) Click the "REBOOT!" button to reset the switch. NOTE: You MUST Reset the switch to activate the new image. Resetting the switch kicks you out of the BBI, so Steps 1-4 need to be executed again before proceeding to the next step. A switch reset completes in approximately 60 seconds. 6) Upgrade the Boot image as follows: a) Fill in the following three (3) fields on the lower half of the page: Hostname or IP Address of FTP/TFTP server => Image Filename => GbESM-AOS-21.0.1.1-boot.img Image for Transfer => boot b) Click the "Get Image" button. Wait for the upgrade to complete successfully. c) Click the "REBOOT!" button to reset the switch. 3.2 How to check the firmware version ------------------------------------- To check the version of the firmware images installed on the GbESM, use either of the following methods: a) From the CLI, execute the command: /boot/cur This command displays (for example): Currently set to boot software image1, active config block. Current FLASH software: image1: version 21.0.1.1, downloaded 0:08:48 Thu Apr 1, 2006 image2: version 20.2.2.7, downloaded 0:09:51 Thu Nov 1, 2005 boot kernel: version 21.0.1.1 b) Using the Management Module GUI, navigate to: Monitors -> Firmware VPD Scroll down to view the VPD info for the appropriate GbE Switch. You should see the following entries: FIRMWARE TYPE BUILD ID RELEASED REVISION ------------- -------- -------- -------- Boot ROM WM01001 04/01/2006 2100 Main Application 1(or 2) WM01001 04/01/2006 2100 The four digits comprising the version (e.g. 21.0.1.0) correlate to the REVISION/BUILD ID as follows: - Revision => 21 00 ... the first 2 digits of the version - Build ID => 01 001 ... the last 2 digits of the version 4.0 Configuration information _____________________________ For detailed switch configuration, please refer to, "Command Reference - Layer 2-7 GbE Switch Module for IBM eServer BladeCenter", available at the web sites indicated in section 6.1. 5.0 Unattended mode ___________________ Unattended Mode is not supported for updating the Nortel Switch Module firmware. 6.0 Web information and support phone number _______________________________ If you have any questions about this update, or problems applying the update, go to the following Help Center World Telephone Numbers and URL: http://www.pc.ibm.com/qtechinfo/YAST-3P2QYL.html.
