Site Requirements
The appliance should be installed in a server room or server cabinet with the following features:
Environment control
An air conditioner, preferably a dedicated computer room air conditioner (CRAC), capable of maintaining the cabinet or
server room at a temperature of no more than 27 degrees C/80.6 degrees F at altitudes of up to 2100 m/7000 ft, or 18
degrees C/64.4 degrees F at higher altitudes, a humidity level no greater than 45 percent, and a dust-free environment.
Power density
Wiring capable of handling at least 4,000 watts per rack unit in addition to power needs for the CRAC.
Rack Requirements
The rack on which you install your appliance should meet the following criteria:
Rack characteristics
Racks should be either integrated into a purpose-designed server cabinet or be the floor-to-ceiling type, bolted down at
both top and bottom to ensure stability. If you have a cabinet, it should be installed perpendicular to a load-bearing wall for
stability and sufficient airflow. If you have a server room, your racks should be installed in rows spaced at least 1 meter/3
feet apart for sufficient airflow. Your rack must allow your IT personnel unfettered access to the front and back of each
server and to all power and network connections.
Power connections
At minimum, two standard power outlets per unit.
Network connections
At minimum, four Ethernet connections per rack unit.
Space requirements
One empty rack unit for the Citrix NetScaler SDX 8015/8400/8600, and two consecutive empty rack units for all other
appliance models.
Note: You can order the following rail kits separately.
Compact 4-post rail kit, which fits racks of 23 to 33 inches.
2-post rail kit, which fits 2-post racks.
Cautions and Warnings
Electrical Safety Precautions
Caution: During installation or maintenance procedures, wear a grounding wrist strap to avoid ESD damage to the
electronics of the appliance. Use a conductive wrist strap attached to a good earth ground or to the appliance. You can
attach it to the connector beside the ESD symbol on the back.
Follow basic electrical safety precautions to protect yourself from harm and the appliance from damage.
Be aware of the location of the emergency power off (EPO) switch, so that you can quickly remove power to the
appliance if an electrical accident occurs.
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.
Use a regulating, uninterruptible power supply (UPS) to protect the appliance from power surges and voltage spikes, and
