Installing the rear system fan
This procedure applies only to 4U server models with non-hot-swap power supplies.
Attention:
v
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 4U server models with non-hot-swap power
supplies, complete the following steps.
1. 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.
2. Carefully turn the server on its side so that it is lying flat, with the cover facing
up.
Attention: Do not allow the server to fall over.
3. Remove the side cover (see “Removing the side cover” on page 166).
4. Remove the air duct.
5. 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.
