Appliance Precautions
Determine the placement of each component in the rack before you install the rails.
Install the heaviest appliance first, at the bottom of the rack, and then work upward.
Distribute the load on the rack evenly. An unbalanced rack is hazardous.
Allow the power supply units and hard drives to cool before touching them.
Install the equipment near an electrical outlet for easy access.
Mount equipment in a rack with sufficient airflow for safe operation.
For a closed or multiple-unit rack assembly, the ambient operating temperature of the
rack environment might be greater than the ambient temperature of the room.
Therefore, consider the lowest and highest operating temperatures of the equipment
when making a decision about where to install the appliance in the rack.
Rack Precautions
Make sure that the leveling jacks on the bottom of the rack are fully extended to the
floor, with the full weight of the rack resting on them.
For a single-rack installation, attach a stabilizer to the rack.
For a multiple-rack installation, couple (attach) the racks together.
Always make sure that the rack is stable before extending a component from the rack.
Extend only one component at a time. Extending two or more simultaneously might
cause the rack to become unstable.
The handles on the left and right of the front panel of the appliance should be used only
for extending the appliance out of the rack. Do not use these handles for mounting the
appliance on the rack.
Connecting a NetScaler Appliance to the Network
Connect the interfaces on the appliance to the network ports on the appropriate
switches by using Ethernet/fiber optic cables.

Warning:
Connecting multiple network ports to the same switch or VLAN can result in a
network loop.
