power supply. The extra power supply on some models serves as a backup. The Citrix
logo and LCD on the front of the NetScaler illuminate after the appliance starts, and
the LCD indicates the operational status of the appliance.

Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the appliance from damage.
w
Be aware of the location of the emergency power off (EPO) switch. If an electrical
accident occurs, you can quickly remove power to the appliance.
w
Use a regulating uninterruptible power supply (UPS) to protect the appliance from
power surges and voltage spikes, and to keep the appliance operating in case of
power failure.
w
Do not work alone when working with high voltage components.
w
Always disconnect the appliance from power before 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. As long as the power cord is plugged in, line voltages may be present in
the power supply, even when the power switch is OFF.
w
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.
w
Make sure that the power supply cords include grounding plugs and are plugged into
grounded electrical outlets.
w
Make sure that the power source can handle the appliance's maximum power
consumption rating with no danger of an overload.
w
A reliable ground must be maintained at all times. Therefore, the rack should be
grounded. Pay particular attention to power supply connections other than the
direct connection to the branch circuit (for example, connections to power strips).
