Important: Only trained and qualified personnel should install, maintain, or replace the appliance.
Power Supply Precautions
Remove all jewelry and other metal objects that might come into contact with power sources or wires before installing
or repairing the appliance. When you touch both a live power source or wire and ground, any metal objects can heat up
rapidly and may cause burns, set clothing on fire, or fuse the metal object to an exposed terminal.
Never stack the appliance on top of any other server or electronic equipment.
Do not block access to the power socket or power sockets where your appliance is plugged in. In emergencies,
unplugging the appliance is the fallback disconnection method.
All appliances are designed to be installed on power systems that use TN earthing. Do not install your device on a power
system that uses either TT or IT earthing.
Ensure that the appliance has a direct physical connection to the earth during normal use. When installing or repairing an
appliance, always ensure that the ground circuit is connected first and is disconnected last.
Ensure that a fuse or circuit breaker no larger than 120 VAC, 15 A U.S. (240 VAC, 16 A international) is used on all current-
carrying conductors on the power system to which your appliances are connected.
Always unplug any appliance before performing repairs or upgrades.
Do not overload the wiring in your server cabinet or on your server room rack.
During thunderstorms, or anticipated thunderstorms located in the vicinity of the building where your appliance is
located, avoid performing any repairs or upgrades until the danger of lightning has passed.
Never touch a power supply when the power cord is plugged in. As long as the power cord is plugged in, line voltages are
present in the power supply even when the power switch is off.
Ensure the stability of your appliance by installing it as follows:
If the appliance is the only unit in the rack, mount it at the bottom of the rack.
When mounting the appliance in a partially filled rack, load the rack from the bottom to the top with the heaviest
server at the bottom of the rack.
If the rack has stabilizing devices available, install them before mounting or servicing the appliance in the rack.
When you dispose of an old appliance or any components, follow any local and national laws on disposal of electronic
waste.
To prevent possible explosions, replace expired batteries with the same model or a manufacturer-recommended
substitute and follow the manufacturer’s instructions on battery replacement.
Never remove a power supply cover or any sealed part that has a label that reads: Hazardous voltage, current, and
energy levels are present inside any component that has this label attached. There are no user-serviceable parts inside
these components. If you suspect a problem with none of these parts, contact Citrix Technical Support.
Appliance Precautions
Determine the placement of each component in the rack before you install the rail.
Install the heaviest appliance on the bottom of the rack first, and then work up. Equipment should be mounted into a
rack so that a hazardous condition does not arise due to uneven mechanical loading.
Allow the power supply units and hot plug hard drives to cool before touching them.

© 1999-2017 Citrix Systems, Inc. All rights reserved. p.14https://docs.citrix.com
To maintain proper cooling, always keep the rack's front door, panels, and appliance components closed.
Install the equipment near a socket outlet for easy access.
If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack environment may be
greater than the ambient temperature of the room. Therefore, consideration should be given to installing the equipment
in an environment compatible with the manufacturer's maximum rated ambient temperature (T mra).
Clearance Precautions
Mount equipment into a rack with airflow sufficient for safe operation.
Leave enough clearance in front of the rack to open the front door completely (25 inches).
Leave approximately 30 inches of clearance behind the rack to allow for sufficient airflow and ease in servicing.
This product is for installation only in Restricted Access Locations (RALs) such as dedicated equipment rooms and service
closets.
Rack Precautions
Ensure that the leveling jackets on the bottom of the rack are fully extended to the floor with the full weight of the
rack resting on them.
In a single rack installation, attach a stabilizer to the rack.
In multiple rack installations, couple (attach) the racks together.
Always make sure the rack is stable before extending a component from the rack.
Extend only one component at a time. Extending two or more simultaneously may cause the rack to become unstable.
