Installing a Side Fan Tray in a QFX3008-I Interconnect Device

 

A QFX3008-I Interconnect device has eight field-replaceable side fan trays. All eight side fan trays are hot-removable and hot-insertable field-replaceable units (FRUs); you can remove and replace the fan tray while the device is running without turning off power to the device or disrupting device functions.

Four fan trays install vertically on the left front of the chassis and four on the right front of the chassis. Handles and captive screws on the two cover panels on each side of the chassis facilitate handling and securing of the fan trays in the chassis.

Before you begin to install a fan tray, ensure that you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.

Ensure that you have the following parts and tools available to install a fan tray in a QFX3008-I Interconnect device:

  • Electrostatic discharge (ESD) grounding strap

  • Replacement fan tray

Caution

The fan trays can be removed and replaced while the QFX3008-I Interconnect device is operating. However, you must replace the fan tray within 2 minutes of removing the fan tray to prevent overheating of the chassis.



To install a fan tray in a QFX3008-I Interconnect device (see Figure 1):

  1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.

  2. Hold the handle of the fan tray with one hand and support the weight of the tray with the other hand. Align the tray with the fan tray guides on the fan tray slot. Slide in the fan tray until it is fully seated in the chassis.

  3. Hold the handle and the screw of the cover panel and align the cover panel at a slight angle to attach the handle end in to the slot.

  4. Push the screw end of the cover panel in to the chassis.

  5. Tighten the captive screw on the cover panel using your fingers.
