Field replacement procedures overview
Isilon IQ nodes contain a number of components that are easily serviced in the field by trained service personnel.
Note: It is important to replace hardware components as soon as possible after becoming aware of a hardware
failure or impending hardware issue.
Before performing maintenance on Isilon hardware, carefully read and understand all relevant safety information and
recommendations. Contact Isilon Technical Support with any questions about Isilon hardware maintenance.
Safety precautions
Safety warnings describe circumstances under which there is risk of electric shock, bodily injury, fire, damage to Isilon
hardware, or loss of data. Failure to heed these warnings may void the product warranty.
• Ensure that the ambient temperature of the environment in which an Isilon node operates does not exceed the
maximum rated ambient temperature: 35° C (95° F).
• Provide proper airflow to Isilon nodes.
• Ensure that the AC supply circuit for each Isilon node is capable of supplying the total current specified on the node
label.
• Properly ground all AC power supply connections. Pay close attention to connections that are not directly connected
to the branch circuit, such as a node connected to a power strip.
• Before performing maintenance on Isilon nodes, disconnect both power cables.
• Do not overload the branch circuit of the AC power supply providing power to the rack cabinet containing Isilon
nodes. The total rack load must not exceed 80 percent of the branch circuit rating.
• To help protect the system from sudden increases or decreases in electrical power, use a surge suppressor, line
conditioner, or uninterruptible power supply (UPS).
• When installing Isilon nodes in a rack cabinet, always use both front and side rack stabilizers. Installing nodes in a
rack cabinet without stabilizers can cause the rack to tip over and potentially result in personal injury.
• Due to the weight of Isilon nodes, use a minimum of two people to install nodes into a rack cabinet. A 4U Isilon
node with the drives installed can weigh up to 130 lbs (57.97 kg). To minimize the chance of injury during node
installation, 4U Isilon nodes must be installed in a rack cabinet without the hard drives installed in the node.
General recommendations
Before replacing components or performing other maintenance operations on Isilon nodes, review these general
recommendations and best practices.
• Only trained and qualified personnel should install or replace equipment.
• Use only approved replacement parts and equipment.
• Handle all electronic components according to the manufacturer instructions.
