appliance. The root password is used to authenticate the root user. The default root
password is nsroot. You can change this password during initial configuration of the
appliance.
Installation
Installation involves rack-mounting the appliance, installing transceivers (if available),
and connecting the appliance to the network and a power source.
Note: The appliances illustrated in the installation instructions might not represent the
actual NetScaler SDX appliance.
Rack Mounting the Appliance
The appliance is shipped with rack-rail hardware. This hardware consists of two inner
rails that you attach to the appliance, one on each side, and a rack-rail assembly that
you attach to the rack. The following figure illustrates the steps involved in mounting
the Citrix NetScaler SDX appliance to a rack.
Figure 1-3. Rack Mounting the Appliance
Appliance Precautions
wDetermine the placement of each component in the rack before you install the rail.
wInstall 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.

wAllow the power supply units and hard drives to cool before touching them.
wInstall the equipment near an electrical outlet for easy access.
wMount equipment in a rack with sufficient airflow for safe operation.
wFor 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
wMake 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.
wFor a single-rack installation, attach a stabilizer to the rack.
wFor a multiple-rack installation, couple (attach) the racks together.
wAlways make sure that the rack is stable before extending a component from the
rack.
wExtend only one component at a time. Extending two or more simultaneously might
cause the rack to become unstable.
wThe 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.
Installing Transceivers
The SDX appliances support only fiber transceivers in the 10GE ports.
Warning: Only those transceivers provided by Citrix Systems, Inc. are supported.
You must not attempt to install third-party transceivers. Doing so voids the warranty.
To install the transceiver
1. Carefully remove the transceiver from its box.
2. Align the transceiver to the front of the transceiver slot on the front panel of the
appliance.
3. Hold the transceiver between your thumb and index finger and insert it into the
transceiver slot, pressing it in until you hear the transceiver snap into place.
4. Lock the transceiver.

Connecting a NetScaler SDX Appliance to the
Network
Connect the interfaces on the appliance to the network ports on the appropriate
switches by using Ethernet/fiber optic cables.
Figure 1-4. Connecting a Citrix NetScaler SDX appliance to the network
Warning: Connecting multiple network ports to the same switch or VLAN can
result in a network loop.
Note: By default, the NetScaler SDX appliance is configured to use auto-negotiation.
When you install a NetScaler appliance for the first time, be sure to configure your
other equipment to use auto-negotiation for the ports that are connected to the
NetScaler appliance. After initial logon and configuration, you can choose to disable
auto-negotiation.
Connecting an SDX Appliance to a Power Source
Connect the power cable to one of the inlet receptacles on the back of the appliance
and connect the other end of the power cable to a power outlet. If your appliance has
more than one power supply, repeat this process. All models function properly with a
single power supply. The extra power supply on some models serves as a backup.

Note:
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.
Basic electrical safety precautions should be followed to protect yourself from harm
and the appliance from damage.
wBe 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.
wUse a regulated, 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.
wDo not work alone when working with high voltage components.
wAlways disconnect the appliance from power before removing or installing any
component. First shut down the appliance, and then unplug the power cords of all
the power supply units. As long as the power cord is plugged in, line voltages can be
present in the power supply, even when the power switch is OFF.
wDo 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.
wMake sure that the power supply cords include grounding plugs and are plugged into
grounded electrical outlets.
wMake sure that the power source can handle the appliance's maximum power
consumption rating with no danger of an overload.
wA 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).
Setting Up Connectivity
After you have installed your appliance in a rack, you are ready to perform the initial
configuration. To perform the initial configuration, you can use the Management
Service user interface or the serial console. You can access the Management Service
user interface from any computer that is on the same network as the new SDX
appliance. If you do not have a computer on the same network, use the serial console
to perform the initial configuration of the SDX appliance. Citrix recommends that, as
soon as you complete the initial configuration, you change the root-user password. For
information about changing the root-user password, see Changing the Password of the
Default User Account.
