What additional information do I need to install my equipment that is not in HWU

Site information and necessary installation tools

Environment requirements for your equipment

When selecting a location to set up your system, ensure that it meets the following general environmental characteristics:

• Site is free of dust and dirt and other particulate contamination.
• There is sufficient room around your system for access to components and for proper airflow around the system.
• Site meets temperature and humidity requirements for the system.
• Site meets the electrical requirements for your equipment.
• Any changes in the site environment that are caused by unforeseen circumstances due to disaster occurrence or prevention would create an environment that is not suitable for system operation and would impact warranty obligations. These conditions could include, but are not limited to water damage, air quality, fire, fire suppressants or other extinguishing systems. 

Ambient temperature and fan speed considerations

• NetApp systems have variable speed cooling fans. At higher ambient temperatures, fans will spin faster and consume more power. This may counteract some energy savings anticipated by raising the ambient temperature.
• You should operate your system within the NetApp-defined operating temperature range, as defined in the HWU. As the temperature increases, the reliability and life expectancy of electronics and hard disk drives decreases.

Required tools and equipment

Prior to receiving your hardware, ensure that you have the appropriate tools and equipment assembled and ready to use:

• Pallet jack, forklift, hand truck or other mechanized lift, depending on what you receive
• #1 and #2 Phillips head screwdrivers and a flathead screwdriver for cable adapters
• A host or client that can attach to a serial console port
• Null modem cable (optional)

If a mechanized lift is not available, multiple people may be required to install certain NetApp products. Consult the installation documentation or HWU for specific weight and lifting considerations.

DC power connections

If you ordered a DC power version of your product, you may require the following items to fabricate the three-way cables required for DC power connections.

For details about your DC power supply, see the DC power supply documentation that came with your DC power supply. You can also find this documentation on the NetApp Support site.
Attention: Do not mix different AC with DC power supplies in your controller.

Additional required tools

• Wire-stripper
• Soldering tool and pliers
• 12 AWG to 6 AWG x 3 copper wire (length determined by environment)
• 3/16'' flathead screwdriver 

Converting watts to volt-amps

Use the following formula to calculate VA from watts with measurements made in the Hardware Universe (HWU):
 
VA = Watts/PF
PF = 0.95
Watts = Watts listed in the individual tables in the HWU

Circuit breaker and power outlet balancing

About the requirements:

NEMA: If your equipment is mounted in a rack, the total number of circuit breakers required for your equipment is based on the current draw. You should not load a circuit beyond 80 percent of the rated limit for the circuit.
Example: If you have a 20A circuit, you should load it to no more than 16A of draw.
 
IEC: If your equipment is mounted in a rack, the total number of circuit breakers required for your equipment is based on the current draw.
Example: If you have a 16A circuit, you should load it to no more than 16A of draw. 
Attention: Overloading circuit breakers can lead to tripped breakers or power brownouts that can cause system errors. 

Balancing the load across PDUs

A best practice is to plan how to distribute the total load across the PDU banks prior to plugging your system components into them. You should make each bank load as equally as possible (applicable to 3-phase PDUs).
 
Keep the following considerations in mind when planning to balance the load:

• Balancing the load depends on the number of components being connected and location of the component power supply units (PSUs), as shown in the following illustrations.
• You should connect the components to different PDUs on opposite sides of the system cabinet, using the illustrations for reference.
• You should plug each component into the PDU outlet directly across from the component, using the illustrations for reference.

Examples of balancing the load with a single component

The following illustrations show three examples of connecting the PSUs of a single component, such as a controller in a single chassis, to the system cabinet PDUs.

PSUs on opposite sides of component:

PSUs on same side of component:

 

PSUs stacked on same side of component:

Examples of balancing the load with two components

The following illustrations show three examples of connecting the PSUs of two components, such as a component with two controller modules in a single chassis or two components close together, to the system cabinet PDUs.
