Description

After installing the jfirmware-junos-evo-install* package with the request system software add command, use this command to upgrade firmware on a system running Junos OS Evolved. You can only upgrade one option at a time; you cannot specify multiple options.

Note:

For firmware upgrades on Junos OS Evolved, we recommend that you work with the Juniper Networks Technical Assistance Center (JTAC).

Options

The fields that are valid may vary depending on the platform and software release.

cb suboptions

Upgrade control board firmware.

  • cg0—(Optional) Upgrade the CG0.

  • gnss—(Optional) Upgrade the GNSS.

  • i2cs-fpga—(Optional) Upgrade the I2CS FPGA.

  • idtpll—(Optional) Upgrade the IDT PLL.

feb suboptions

Upgrade FEB ROM monitor.

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

  • cg(1|2|3)—(Optional) Upgrade the CG.

  • ctrl-fpga—(Optional) Upgrade the control FPGA.

  • i2cs-fpga—(Optional) Upgrade the I2CS FPGA.

  • port-a-fpga—(Optional) Upgrade the FPGA for port A.

  • port-b-fpga—(Optional) Upgrade the FPGA for port B.

  • power-controller—(Optional) Upgrade the power controller firmware.

fpc suboptions

    • 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.

  • pmb-bios—(Optional) Upgrade the BIOS.

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

ftc slot (0 | 1)

Upgrade the fan tray controller firmware.

pic

Upgrade the PIC firmware.

psm

Upgrade the power supply module 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 PSM remains offline with an alarm of firmware mismatch. This mismatch causes a corresponding PSM output shutdown, causing the PSM 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.

root@host-re0> request system firmware upgrade psm slot 0
WARNING: Please ensure all inputs are connected to this PSM; otherwise, PSM will undergo a partial upgrade and go offline.
Perform indicated firmware upgrade? [yes, no] (no)

  • slot slot-number—(Optional) Upgrade a particular power supply module.

re suboptions

Upgrade the baseboard BIOS/FPGA. There is an active BIOS image and a backup BIOS image. Updates all of the firmware on the Routing Engine unless specified with one of the suboptions below:

  • bios—(Optional) Upgrade the BIOS.

  • cpld—(Optional) Upgrade the CPLD.

  • fancpld—(Optional) Upgrade the fanboard CPLD.

  • fpga—(Optional) Upgrade the baseboard FPGA.

  • i210—(Optional) Upgrade the baseboard i210 GbE NIC.

  • i40nvm—(Optional) Upgrade the baseboard i40 non-volatile memory.

  • nac-fw—(Optional) Upgrade the network access control firmware.

  • ssd—(Optional) Upgrade the Routing Engine solid-state drive (SSD) firmware.

    • disk1—Upgrade the SSD disk1 firmware.

    • disk2—Upgrade the SSD disk2 firmware.

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.

sib <slot (0 | 1)>

Upgrade SIB firmware.
