Install PLD (If a Newer Version is Available)

GigaVUE-HC3, GigaVUE-HC1, GigaVUE‑HC1-Plus, and GigaVUE-HCT devices include field programmable gate arrays (FPGAs). PLD upgrade packages are included within the GigaVUE-OS image upgrades of these devices (no separate package or file to download).

Before upgrading PLD, check if a newer version of PLD is available. Use the show pld command to determine the same.

(config) # show pld

If the show pld output indicates "Need Upgrade: yes", plan and perform the upgrade for one PLD slot at a time. Use the pld upgrade slot <boxid>/<slot> command to upgrade.

Note:  During each PLD slot upgrade do not power cycle the chassis, remove the card, shutdown the card.

Refer to the pld section in the GigaVUE-OS CLI Guide for details.

Rules, Notes, and Limitations for PLD Upgrade

Refer to the following rules and notes for PLD upgrades:

  • In clusters: Executing the PLD commands on the cluster leader will only show or upgrade PLDs for card modules directly inserted into the cluster leader. Therefore, log into each device with PLD-capable modules to inspect or upgrade those modules.
  • The show pld output will continue to indicate "Need Upgrade: yes" for a slot after a successful PLD upgrade until the chassis is power cycled and the new PLD version is being used.
  • When upgrading multiple slots in a chassis, carefully note which slots you have already upgraded during the process.
  • Although the pld upgrade command identifies a slot to upgrade using <boxid>/<slot>, in a cluster, this command only upgrades card modules directly inserted into the local chassis.
  • Each PLD upgrade will take several minutes to complete.
  • Upgrading the PLD on a single GigaVUE-HC3 SMT-HC3-C05 module will take approximately 2 to 3 minutes.
  • If a PLD upgrade fails on the first attempt, immediately repeat the PLD upgrade on the same PLD slot a second time. No chassis power cycle is required between the two PLD upgrade attempts on the same PLD slot. If the second PLD upgrade attempt fails, then contact Gigamon Technical Support for further troubleshooting and recommendations.
  • The card module that failed the PLD upgrade will likely need to be replaced via RMA. Contact Gigamon Technical Support for assistance.
  • It is not recommended to power cycle a chassis or remove/re-insert a card module after a failed PLD upgrade - the module may not return to an operational state or operate with issues.
  • After PLD upgrade(s) is/are successfully completed, a power cycle operation is required for new firmware to take effect. Refer to the following table for details:

      • Device

      Slots/cards involved in PLD upgrade

      Operation required after a successful upgrade

      GigaVUE‑HC1/GigaVUE‑HC1-Plus/GigaVUE-HCT

      Main board (Slot 1) only.

      Chassis power cycle.

      • PLD upgrades on various modules and the main board can be executed sequentially in no particular order, followed by a single chassis power cycle.

      • Reloading the chassis without a power cycle is not sufficient. The chassis must be completely powered down and then powered back on.

      • All the power supplies must be powered off for chassis with multiple power supplies.

      • For DC-powered chassis, temporarily remove the DC fuses in the top-of-rack fuse panel.

       

       

      Main board (Slot 1) and one or more modules (Slot 2 and above).

      GigaVUE‑HC1-Plus

      Rear GigaSMART module (Slot 4) only.

      Rear GigaSMART module (Slot 4) and one or more front modules (Slots 2-3).

      GigaVUE‑HC3

       

      Main board (Slot cc1) only.

      Main board (Slot cc1) and one or more modules (Slots 1-4).

      Any GigaVUE TA Series appliance

      Only the main board (Slot 1) is applicable.

      G-TAP A Series

      Only the main board is applicable.

      GigaVUE‑HC1/GigaVUE‑HC1-Plus/GigaVUE-HCT/GigaVUE‑HC3

      One or more modules only. The main board (or Rear GigaSMART module in GigaVUE‑HC1-Plus) is not involved.

      The upgraded module(s) should be shut down, physically removed, and re-inserted.

      Alternatively, the chassis power cycle as described above can be done.
