Replacing the Cooling Fans

The SA 6500 ships with two cooling fans installed in the back of the chassis. If you need

to replace one of the cooling fans, you can “hot-swap” the faulty fan for a replacement

during operation in a matter of moments. You can purchase additional cooling fans from

your authorized Juniper reseller, or you can purchase them in the future to replace faulty

or failed cooling fans, as necessary.

To remove and install a cooling fan module:

1. To release the cooling fan module, do one of the following:

•

Press and slide the release trigger toward the center of the cooling fan module

•

Loosen the thumbscrews

2. Grasp the cooling fan module and carefully pull it out.

CAUTION: Once you remove the cooling fan module, it is important that

you replace it with a replacement cooling fan. The second fan is required

for proper air flow across the chassis’s internal components; it is not a

redundant fan.

3. Line the a cooling fan module up with an empty cooling fan port on the back of the

chassis.

4. Slowly slide the module into the chassis until it clicks into place.

5. If your cooling fan is equipped with thumb screws, tighten the screws.
