Specifications
The NetScaler hardware platforms range from the single
processor MPX 5500 platform to the high-capacity, MPX
22040/22060/22080/22100/22120 hardware platform. The
various NetScaler hardware platforms are similar in that they
use the same types of components, but different models
provide different hardware capabilities. All NetScaler
hardware platforms support the NetScaler software.
Some of the hardware platforms are available as dedicated
application firewall appliances or secure application access
appliances.

Chapter 1 Introduction to the Hardware Platforms
Common Hardware Components
Each platform has front panel and back panel hardware components. The front panel
has an LCD display and an RS232 serial console port. The number, type, and location of
ports—copper Ethernet, copper and fiber 1G SFP, 10G SFP+, and XFP—vary by hardware
platform. The back panel provides access to the fan and the field replaceable units
(power supplies, CompactFlash card, and solid-state and hard-disk drives).
LCD Display
The LCD display on the front of every appliance displays messages about the current
operating status of the appliance. These messages communicate whether your
appliance has started properly and is operating normally. If the appliance is not
operating normally, the LCD displays troubleshooting messages.
The LCD displays real-time statistics, diagnostic information, and active alerts. The
dimensions of the LCD limit the display to two lines of 16 characters each, causing the
displayed information to flow through a sequence of screens. Each screen shows
information about a specific function.
The LCD has a neon backlight. Normally, the backlight glows steadily. When there is an
active alert, it blinks rapidly. If the alert information exceeds the LCD screen size, the
backlight blinks at the beginning of each display screen. When the appliance shuts
down, the backlight remains on for one minute and then automatically turns off.
There are nine types of display screens on the LCD display. The first two screens in the
following list, the booting screen and the startup screen, appear when your appliance
is starting up. The other screens, except the out-of-service screen, can appear while
the appliance is operating. They show configuration information, alerts, HTTP
information, network traffic information, CPU load information, and port information
for your appliance.
Booting Screen.
The booting screen is displayed immediately after the appliance is turned on. The
first line displays the hardware platform, as shown in the following figure.

Ports are used to connect the appliance to external devices. NetScaler appliances
support RS232 serial ports, 10/100/1000Base-T copper Ethernet ports, 1-gigabit copper
and fiber 1G SFP ports, and 10-gigabit fiber SFP+ and XFP ports. All NetScaler
appliances have a combination of some or all of these ports. For details on the type
and number of ports available on your appliance, see the section describing that
platform.
16
RS232 Serial Port
The RS232 serial console port on the front panel of each appliance provides a
connection between the appliance and a computer, allowing direct access to the
appliance for initial configuration or troubleshooting.
All hardware platforms ship with an appropriate serial cable used to connect your
computer to the appliance. For instructions on connecting your computer to the
appliance, see "Installing the Hardware."
Copper Ethernet Ports
The copper Ethernet ports installed on many models of the appliance are standard RJ45
ports.
There are two types of copper Ethernet ports that may be installed on your appliance:
10/100BASE-T port
The 10/100BASE-T port has a maximum transmission speed of 100 megabits per
second (Mbps). Most platforms have at least one 10/100BASE-T port.
10/100/1000BASE-T port
The 10/100/1000BASE-T port has a maximum transmission speed of 1 gigabit per
second, ten times faster than the other type of copper Ethernet port. Most platforms
have at least one 10/100/1000Base-T port.
Citrix NetScaler Hardware Installation and Setup Guide
To connect any of these ports to your network, you plug one end of a standard Ethernet
cable into the port and plug the other end into the appropriate network connector.
Management Ports
Management ports are standard copper Ethernet ports (RJ45), which are used for direct
access to the appliance for system administration functions.
1G SFP, 10G SFP+, and XFP Ports
A 1G SFP port can operate at a speed of 1 Gbps. It accepts either a copper 1G SFP
transceiver, for operation as a copper Ethernet port, or a fiber 1G SFP transceiver for
operation as a fiber optic port.
The 10G SFP+ and XFP ports are high-speed ports that can operate at speeds of up to
10 Gbps. You need a fiber optic cable to connect to a 10G SFP+ or XFP port. If the other
end of the fiber optic cable is attached to a 1G SFP port, the 10G SFP+ port
automatically negotiates to match the speed of the 1G SFP port.
The following tables list the maximum distance specifications for NetScaler pluggable
media (1G SFP, 10G SFP+, and XFP transceivers).
Note: The tables are categorized by 1G pluggable media and 10G pluggable media.
The 10G SFP+ modules are dual-speed capable and support both 1G and 10G,
depending on the peer switch that the model connects to. These are listed in both
tables.

Chapter 1 Introduction to the Hardware Platforms
Field Replaceable Units
Citrix NetScaler field replaceable units (FRU) are NetScaler components that can be
quickly and easily removed from the appliance and replaced by the user or a technician
at the user's site. The FRUs in a NetScaler appliance can include a CompactFlash card,
DC or AC power supplies, and solid-state or hard-disk drives, and a direct attach cable
(DAC).
Note: The solid-state or hard-disk drive stores your configuration information, which
has to be restored from a backup after replacing the unit.
Power Supply
For appliances containing two power supplies, the second power supply acts as a
backup. The MPX 22040/22060/22080/22100/22120 can accommodate four power
supplies, and require two power supplies for proper operation. The third and fourth
power supplies act as backup.
The appliance ships with a standard power cord that plugs into the appliance’s power
supply and an NEMA 5-15 plug on the other end for connecting to the power outlet on
the rack or in the wall.
For power-supply specifications, see "Hardware Platforms," which describes the various
platforms and includes a table summarizing the hardware specifications.
Note: If you suspect that a power-supply fan is not working, please see the description
of your platform. On some platforms, what appears to be the fan does not turn, and the
actual fan turns only when necessary.
For each power supply, a bicolor LED indicator shows the condition of the power supply.
The LEDs of the AC power supplies for MPX 15000 and 17000 appliances are different
from the LEDs of the other appliances.
