Maintaining QFX5130-32CD Cooling System

The fan modules in QFX5130-32CD are hot-removable and hot-insertable field-replaceable units (FRUs): you can remove and replace one of them without powering off the switch or disrupting switching function.

CAUTION:

To ensure proper airflow, keep a failed fan module in place until you have a replacement fan module at hand. Do not run the device with an open fan tray slot for an extended amount of time.

How to Remove a Fan Module from a QFX5130-32CD

Before you remove a fan module from a QFX5130-32CD, ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).

Ensure that you have the following parts and tools available to remove a fan module from a QFX5130-32CD:

  • ESD grounding strap

  • Antistatic bag or an antistatic mat

To remove a fan module from a QFX5130-32CD (see Figure 1:

  1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  2. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  3. Loosen the locking screw (3 or 4 turns) using a Phillips number 2 screwdriver..
  4. Grasp the handle on the fan module and squeeze the outside of the handle to release the module.
    Warning:

    To avoid injury, do not touch the fan with your hands or any tools as you slide the fan module out of the chassis—the fan might still be running.

  5. Pull firmly to slide the fan module halfway out of the chassis.
  6. When the fan stop spinning, use your other hand to support the fan and slide the fan module completely out of the chassis.
  7. Place the fan module in the antistatic bag or on the antistatic mat placed on a flat, stable surface.

Note:

When a fan module is removed, the CLI message Fan/Blower is Absent is logged in the system log, and the system raises a minor alarm.

How to Remove a Fan Module in a QFX5130-32CD

Before you install a fan module in a QFX5130-32CD, ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).

The fan modules in a QFX5130-32CD are hot-removable and hot-insertable field-replaceable units (FRUs); you can remove and replace them without powering off the switch or disrupting switch functions.

CAUTION:

To ensure proper airflow, keep a failed fan module in place until you have a replacement fan module at hand. Do not run the device with an open fan tray slot for an extended amount of time.

Note:

The fan module provides FRU-to-port or port-to-FRU airflow depending on the switch product variant you purchase.

To install a fan module in a QFX5130-32CD (see Figure 2.):

  1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  2. Take care not to touch the connectors as you remove the fan module from its bag.
  3. Align the module with the open slot on the management panel of the chassis and slide it in until it is fully seated.

    CAUTION:

    Damage can occur if you attempt to install a fan module into a chassis with a different airflow direction. Compare the switch product variant with the airflow marking on the handle to ensure that you are installing a fan module with the same airflow direction as the chassis. The fan modules are designed so that they can only be inserted into the QFX5130-32CD product variant that supports the same airflow type. SeeQFX5130-32CD Power System for more information.

  4. Use a Phillips number 2 screwdriver to tighten the locking screw.
