Installing/removing a fan module
CAUTION:
• Install two fan modules of the same model on the switch. Do not power on the switch when it
does not have a fan module or has only one fan module installed.
• Make sure slots are installed with fan modules or blank filler panels for the device to operate.
• If both fan modules fail during operation, replace them within 2 minutes while the switch is
operating.
• If one fan module fails, perform either of the following tasks:
If the ambient temperature is not higher than 27°C (80.6°F), replace the fan module within 24 hours
and make sure the failed fan module is in position before the replacement.
If the ambient temperature is higher than 27°C (80.6°F), replace the fan module immediately.
The switch comes with empty fan module slots. Choose the fan module models based on the
ventilation requirement of the site. The air flow direction varies by fan module model.

The HPE 5944 FAN Module with Power to Port Airflow (JL838A) has a blue handle and
provides power-to-port air flow.
Installing a fan module
CAUTION:
To prevent damage to the fan module or the connectors on the backplane, insert the fan module
gently. If you encounter a hard resistance while inserting the fan module, pull out the fan module and
insert it again.
To install a fan module:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Unpack the fan module and verify that the fan module model is correct.
3.
Grasp the two handles of the fan module with the side marked TOP facing up, and slide the fan
module along the guide rails into the slot until the fan module seats in the slot and has a firm
contact with the backplane.
