Replacing the rear system fan

This procedure applies only to 4U server models with non-hot-swap power supplies.

Attention
To ensure proper cooling and airflow, do not operate the server for more than 30 minutes with the side cover removed.

To install the rear system fan on the 4U server model with non-hot-swap power supplies, complete the following steps.

  1. Read the safety information in Safety and Installation guidelines.
  2. The replacement fan comes with the rubber grommets installed; however, they might have come out during shipment. If any of the rubber grommets are missing from the fan, install them on the fan before you continue. Use needle-nosed pliers to pull the grommets through the holes in the fan.
  3. Position the fan so that the grommets protrude through the holes in the chassis; then, use needle-nosed pliers to pull the grommets through the holes from outside the chassis.
