Determining sufficient air conditioning

To determine whether you have sufficient cooling for your site, complete the following steps.

Step	Action
1	Add the BTU rates for all storage appliances, disk shelves, and any other hardware you plan to keep in one room.
2	Determine whether the air conditioning in your room can handle the total BTU rate. Note If you need help in determining the total BTU rate, contact the heating/cooling expert for your site.
3	If your room air conditioning cannot handle the BTU load of all your hardware, upgrade the air conditioning or install your hardware in another room.

Step

Action

Add the BTU rates for all storage appliances, disk shelves, and any other hardware you plan to keep in one room.

Determine whether the air conditioning in your room can handle the total BTU rate.

Note
If you need help in determining the total BTU rate, contact the heating/cooling expert for your site.

If your room air conditioning cannot handle the BTU load of all your hardware, upgrade the air conditioning or install your hardware in another room.
