Replacing the Fan Tray on the SRX3600 Services Gateway

The services gateway has one fan tray that installs vertically in the right rear of the chassis. The fan tray contains 10 fans. The fan tray is hot-removable and hot-insertable. It weighs about 6.2 lb (2.8 kg).

Note: To prevent overheating, install the replacement fan tray immediately after removing the existing fan tray.

To replace the fan tray:

  1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage to the SRX3600 Services Gateway.
  2. Turn the screw to the left on the fan tray door. Open it to the right and remove it.

  3. Grasp the fan tray and pull it out 1 in. (2.5 cm) to disengage its power connection. A mechanical latch stops the fan tray from coming out any further.
  4. Wait for the fans to stop spinning.

    Warning: To avoid injury, do not proceed until the fans have stopped spinning.

  5. After the fans have stopped spinning, lift upward on the latch at the bottom of the fan tray to release it. See Figure 47.

  6. Grasp the fan tray and pull it out approximately 6 in. (15 cm).
  7. Place one hand under the fan tray to support it and pull the fan tray completely out of the chassis and set it aside.
  8. Grasp the replacement fan tray and insert it straight into the chassis until you hear a click, indicating the latch has closed.

    Note: Be sure the fan tray is correctly oriented in the slot, with the latch on the bottom of the vertically aligned fan tray.

  9. Press the fan tray into the chassis about 1 in. (2.5 cm) beyond where the latch closes to engage the power connection.
