n26000/28000 Appliances (excluding 28600HS)
Important
nRead the Health and Safety Information in the relevant guide:
16000 Appliances Getting Started Guide
26000 and 28000 Appliances Getting Started Guide
nTo protect the appliance and cooling fans from electrostatic discharge, make sure that you are
grounded.
nWe recommend that you use an ESD grounding wrist strap. Connect the grounding plug on the wrist
strap to the chassis grounding point.
nYou can hot swap one cooling fan unit at a time. A cooling fan unit consists of two fans in
16000/16200 appliances and four fans in 26000/28000 appliances.
Important - When removing a failed cooling fan unit, Check Point recommends that you complete
the procedure within 3 minutes to avoid a temporary impact on performance.
If you require additional time, Check Point recommends that you shut down the appliance
beforehand.

In 26000/28000 appliances Units are numbered in stacks of two (one inner and one outer) for a total of 8
fans. When checking the hardware sensors in the CLI, they are referred to as 1-4 inside and 1-4 outside.
See also "Cooling Fan Units Naming Convention" on the next page .
Caution - Components inside the appliance can overheat if they are not cooled, even for
a short period of time.
To prevent damage caused by too much heat:
nWhen a cooling fan unit fails, replace it as soon as possible
nIf more than one cooling fan unit fails, we recommend that you shut down the
appliance
nDo not hot swap more than one cooling fan unit at a time
To replace a fan unit:
1. Loosen the screws on the cooling fan unit to be replaced.
2. Hold the screws and pull the cooling fan unit away from the appliance.
3. Position the new cooling fan unit in the empty cooling fan tray slot in the appliance.
4. Tighten the screws on the cooling fan unit.
