Installing the rear system fan
Attention:
v Replace a failed fan within 48 hours.
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, 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. 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.
3. Connect the fan cable to the system board (see “System-board internal
connectors” on page 8 for the location of the rear fan connector).
4. Install any adapters that you removed (see “Installing an adapter” on page 37).
5. Install the side cover (see “Installing the side cover” on page 31).
6. Lock the side cover if you unlocked it during removal.
7. Reconnect the external cables and power cords; then, turn on the attached
devices and turn on the server.
