Firmware Updating Procedures
|
This appendix describes the firmware updating procedures for the switch and includes the following topics:
Overview
Following is the list of firmware that is on the switch:
- IPMC firmware
- Base firmware
- Base U-Boot loader
- Base Linux operating system
- Base FASTPATH
- Fabric firmware
- Fabric U-Boot boot loader
- Fabric Linux operating system
- Fabric FASTPATH
All of the firmware listed are field upgradable. There is a single update image that supports the Base firmware, Fabric firmware, and IPMC firmware. This update image must be installed twice: once on the Base and once on the Fabric. The IPMC update happens during a Base update. Each component listed above can be updated independently without affecting the other components; for example, the FASTPATH component can be updated without affecting the uBoot and Linux components.
Testing Updates Before Installing Them
The switch supports network booting. This feature can be used to test updates to FASTPATH without installing them. Updates containing changes to U-Boot, Linux, or the IPMC must be installed to the flash before they can be used.
1. Set up a TFTP server on the update network.
The update network is the network where the update image is stored.
2. Place the update image on the TFTP server.
The update image will have a .tgz file extension.
3. Connect to the serial management port of the Base or Fabric network to be updated and connect the MGMT port to the update network.
4. Reset the switch.
Following are the different methods that you can use to reset the switch:
- Press the reset button on the switch.
- Disengage and reengage the card injector/ejector mechanisms at the top and bottom of the card.
- Execute the reload command through the switch software.
5. As the switch resets, press 2 to enter the Utility Menu.
6. Press 8 to change the boot method.
7. Press 3 to select network as the boot method.
8. Enter the necessary information for your TFTP server.
For the host IP field, you can enter dhcp if you would like to use DHCP to obtain a valid IP address.
9. Press 1 to boot the system.
Use option 8 of the Utility Menu to change the boot method back to flash, if necessary.

Updating the Switch Firmware Through the Boot Utility Menu
1. Set up a TFTP server on the update network.
The update network is the network where the update image is stored.
2. Place the update image on the TFTP server.
The update image will have a .tgz file extension.
3. Connect to the serial management port of the Base or Fabric network to be updated and connect the MGMT port to the update network.
4. Reset the switch.
Following are the different methods that you can use to reset the switch:
- Press the reset button on the switch
- Disengage and reengage the card injector/ejector mechanisms at the top and bottom of the card
- Execute the reload command through the switch software
5. As the switch resets, press 2 to enter the Utility Menu.
6. Press 2 to choose to update the firmware through TFTP.
7. Enter the necessary information for your TFTP server.
For the host IP field, you can enter dhcp if you would like to use DHCP to obtain a valid IP address.
8. Once the update is complete, reset the switch.
If the update is only for the FASTPATH software, you do not need to reboot and can press 1 instead.
9. Repeat these steps for the other network interface.

Updating the Switch Firmware Through the FASTPATH Software
These instructions cover all firmware updates initiated through the FASTPATH software.
1. Set up a TFTP server on the update network.
The update network is the network where the update image is stored.
2. Place the update image on the TFTP server.
The update image will have a .tgz file extension.
3. Determine if you are using telnet, SSH, or SNMP.
- If you are using telnet, SSH, or SNMP, skip to Step 7.
- If you are not using telnet, SSH, or SNMP, then continue with Step 4.
4. Connect to the serial management port of the Base or Fabric network to be updated.
5. Log in to the switch.
6. Configure the network of the switch that you are upgrading.
You can configure the network using either the out-of-band management or the in-band network.
- If you are using the out-of-band management, connect the MGMT port, either through the front panel of the switch or through the rear transition card, to the update network.
- If you are using DHCP, enter the following command:
serviceport protocol dhcp
|
| Note - If you are using DHCP for the serviceport, then you must disable DHCP for the network using the network protocol none command.
|
- If you are using forced IP, enter the following commands:
serviceport protocol none
serviceport ip <ipaddr> <subnet> [gateway]
|
- If you are using the in-band network, connect any port of the network to your update network (if you have the TFTP server on a node board then you can skip this step).
- If you are using DHCP, enter the following command:
| Note - If you are using DHCP for the serviceport, then you must disable DHCP for the network using the network protocol none command.
|
- If you are using forced IP, enter the following commands:
network protocol none
network parms <ipaddr> <subnet> [gateway]
|
7. Download and install the updated firmware.
- If you are using serial, telnet, or SSH, enter the following command to start the code update:
copy tftp://<your_tftpip>/<dir>/<filename> system:image
|
- If using SNMP, perform the following:
- Load the FASTPATH-SWITCHING MIB.
- Use the agentTransferUploadGroup to update the code.
8. Reboot the card:
9. Repeat these steps for the other network.
