Note
If you wish to update to the latest release of the system software before proceeding, see the
NetScaler Migration Guide. This document is located in the /var/netscaler/doc directory on your
appliance. You can also access the document by logging on to the appliance using a Web
browser and selecting the Documentation tab in the configuration utility.
Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm and the appliance
from damage.
• Be aware of the location of the emergency power off switch to disconnect the electrical outlet. If an
electrical accident occurs, you can quickly remove power from the appliance.
• Use of a regulating uninterruptible power supply (UPS) protects the appliance from power surges
and voltage spikes and keeps the appliance operating in case of power failure.
• Do not work alone when working with high voltage components.
• Always disconnect power from the appliance when removing or installing any component. When
disconnecting power, you should first shut down the appliance and then unplug the power cords of
all the power supply units connected to the appliance.
• Do not use mats designed to decrease static electrical discharge as protection from electrical
shock. Instead, use rubber mats that have been specifically designed as electrical insulators.
• The power supply cords must include a grounding plug and must be plugged into grounded
electrical outlets.
• Consideration should be given to the connection of the equipment to the power supply circuitry
and the effect of what a circuit overload might have. Appropriate consideration of equipment
nameplate railings should be used when addressing this concern.
• A reliable ground must be maintained at all times. To ensure this, the rack should be grounded.
Particular attention should be given to power supply connections other than the direct connection
to the branch circuit (for example, the use of power strips).
