Troubleshooting an overheating NPS system

Answer

If a Netezza appliance is "exceeding board temperatures" on ALL SPUs/SFIs, it is likely that an environmental problem is occurring. (The upper SPAs generally tend to be hotter because heat rises and many datacenters have the air conditioning (A/C) in the floor which makes the lower components cooler.)

1. Contact personnel in the datacenter and ask the following questions:

• Have there have been an recent additions to the datacenter?
• The addition of a machines at the other end of the room can affect the overall temperature of the room.

• Is the ventilation system up to code? Has the A/C in the datacenter been subject to maintenance tests recently?

• Could a recent heat wave be affecting the building?

• Is anything preventing the A/C from cooling the Netezza appliance?

• Is there anything blowing an excessive amount of hot air onto the Netezza appliance?

• Is it possible to increase the amount of A/C reaching the Netezza appliance? For example, are there floor panels with larger holes available? If so, please put those panels in front of the Netezza appliance.

• As a temporary solution, please open the cabinet doors of the Netezza appliance.
