Description

Use this command to upgrade firmware and optics module on a system running Junos OS.

Options

The following table lists all possible options for the request system firmware upgrade command. The fields that are valid may vary depending on the platform and software release.

Use Feature Explorer to confirm platform and release support for specific features.

Review the Platform-Specific Behavior section for notes related to your platform.

  • progress—(Optional) Check the progress of BIOS upgrade.

cb

Upgrade baseboard FPGA.

  • fancpld—(Optional) Upgrade fanboard CPLD.

  • fpga—(Optional) Upgrade baseboard FPGA.

  • optics—(Optional) Upgrade optics CPLD.

  • port-fpga—(Optional) Upgrade baseboard PORT FPGA.

  • progress—(Optional) Check the progress of system CPLD upgrade.

eusb

Upgrade eUSB firmware.

  • progress—(Optional) Check the progress of eUSB firmware upgrade.

fpc

Upgrade FPC ROM monitor.

  • bcm-pfe—(Optional) Upgrade BCM PFE chip.

  • dpll—(Optional) Upgrade FPC DPLL firmware.

  • dpll-cfg—(Optional) Upgrade FPC DPLL configuration.

  • opticscpld<0|1|2|3>—(Optional) Upgrade optics CPLD.

    • opticscpld0—Upgrade optics CPLD 0.

    • opticscpld1—Upgrade optics CPLD 1.

    • opticscpld2—Upgrade optics CPLD 2.

    • opticscpld3—Upgrade optics CPLD 3.

    Note:

    Run the show system firmware command to verify the number of optics CPLDs supported on your device.

  • slot slot-number—(Optional) Upgrade all devices in a particular FPC slot.

    After you upgrade the firmware on the LC4800 or the LC9600 line card, the line card may go offline. If this happens, use the request chassis fpc slot-number restart command to restart the line card.

fpm

Upgrade front panel module firmware.

ftc slot (0 | 1)

Upgrade fan tray controller firmware.

mmc

Upgrade the eMMC firmware.

  • progress—(Optional) Check the progress of eMMC upgrade.

pem slot slot-number mcu (primary | secondary)

Upgrade PEM firmware.

Within the JNP10K-PWR-AC3 module, there are four types of MCUs; primary, secondary, communication, and LED. This module contains four primary MCUs; however, you can operate the device with three or fewer input leads attached. Before upgrading the firmware on this module, however, you must reattach all of the unattached input leads to ensure that all of the primary MCUs are upgraded to the same firmware version. If you do not reattach an unattached lead, the primary MCU corresponding to that lead is not upgraded, and the PEM remains offline with an alarm of firmware mismatch. This mismatch causes a corresponding PEM output shutdown, causing the PEM to appear offline to avoid issues caused by different firmware versions. If you did not ensure that all of the leads were attached before upgrading and now have the alarm firmware mismatch, attach all of the leads and repeat the firmware upgrade to clear the alarm.

Note:

To upgrade the re fpga component from version 0x0108 to 0x010A on QFX5130-32CD, the upgrade must be performed twice since the first upgrade command upgrades the component to version 0x0109.

sfb slot slot-number tag tag-number

Upgrade the SF2 and SFB2 switch fabric firmware. slot-number can be 0 to 5. For tag tag-number option, specify the tag number that indicates you want to update the FPGA. To find out what number you should use for the tag option, issue the show system firmware command. For example, the show system firmware command shows the tag numbers in the third column as follows:
