The front panel of the Command Center appliance has RS232 serial ports and 10/100/100Base-T copper Ethernet ports. The back panel provides access to the power supply, fan, CompactFlash card, and hard-disk drive.

This topic includes the following details:
  • Ports
  • Power Supply
  • Hard Disk Drive

Ports

RS232 Serial Port

The RS232 serial console port provides a connection between the appliance and a computer, allowing direct access to the appliance for initial configuration or troubleshooting.

Copper Ethernet Ports

The copper Ethernet ports installed on 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).
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.

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.

Note: These ports are not used in the current release.

Management Ports

Management ports are standard copper Ethernet ports (RJ45), which are used for direct access to the appliance for system administration functions.
Note: Use the management port numbered 0/1 to get direct access to the appliance.
Note: This section applies to the MPX 5500, MPX 5550/5650, MPX 7500/9500, MPX 8005/8015/8200/8400/8600/8800, MPX 9700/10500/12500/15500, MPX 17500/19500/21500, MPX 11500/13500/14500/16500/18500/20500, MPX 11515/11520/11530/11540/11542, MPX 11515/11520/11530/11540/11542, MPX 14000, and MPX 17550/19550/20550/21550, and MPX 22040/22060/22080/22100/22120, MPX 22040/22060/22080/22100/22120, MPX 24100/24150, and MPX 25100T/25160T appliances.

The port LEDs show whether a link is established and traffic is flowing through the port. The following table describes the LED indicators for each port. There are two LED indicators for each port type.

Solid yellow Link is established but no traffic is passing through the port.
Blinking yellow Traffic is passing through the port.

Power Supply

For appliances containing two power supplies, the second power supply acts as a backup. The MPX 22040/22060/22080/22100/22120 appliance can accommodate four power supplies, and require two power supplies for proper operation. The third and fourth power supplies act as backup. The MPX 22040/22060/22080/22100/22120 and MPX 24100/24150 appliances can accommodate four power supplies, and require two power supplies for proper operation. The third and fourth power supplies act as backup.

 

For power-supply specifications, see Hardware Platform, which describes the various platforms and includes a table summarizing the hardware specifications.

The MPX 7500 appliance ships with a dual power supply configuration, including two standard power cords that each have a NEMA 5-15 plug for connecting to the power outlet on the rack or in the wall.

Electrical Safety Precautions for Power Supply Replacement

  • Make sure that the appliance has a direct physical connection to earth ground during normal use. When installing or repairing an appliance, always connect the ground circuit first and disconnect it last.
  • Always unplug any appliance before performing repairs or upgrades.
  • 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 if the power switch is turned off.

Replacing an AC Power Supply

Citrix NetScaler MPX platforms can accommodate two power supplies, except the MPX 22040/22060/22080/22100/22120 platform which can accommodate four power supplies, except the MPX 22040/22060/22080/22100/22120 and MPX 24100/24150 platforms which can accommodate four power supplies. All NetScaler appliances function properly with a single power supply, except the MPX 22040/22060/22080/22100/22120 platform which needs two power supplies for proper operation, except the MPX 22040/22060/22080/22100/22120 and MPX 24100/24150 platforms which need two power supplies for proper operation. The other power supplies serves as a backup. All power supplies must be of the same type (AC or DC).

Note: If the appliance has only one power supply, you have to shut down the appliance before replacing the power supply. If the appliance has two power supplies, you can replace one power supply without shutting down the appliance, provided the other power supply is working, and if the appliance has four power supplies, you can replace one or two power supplies without shutting down the appliance, provided the other two power supplies are working, and if the appliance has four power supplies, you can replace one or two power supplies without shutting down the appliance, provided the other two power supplies are working.
To install or replace an AC power supply on a Citrix NetScaler appliance
  1. Align the semicircular handle perpendicular to the power supply. Loosen the thumbscrew and press the lever toward the handle and pull out the existing power supply, as shown in the following figure.
    Note: The illustration in the following figures might not represent the actual NetScaler appliance.
    Figure 1. Removing the Existing AC Power Supply


  2. Carefully remove the new power supply from its box.
  3. On the back of the appliance, align the power supply with the power supply slot.
  4. Insert the power supply into the slot and press against the semicircular handle until you hear the power supply snap into place.
    Figure 2. Inserting the Replacement AC Power Supply


  5. Connect the power supply to a power source. If connecting all power supplies, plug separate power cords into the power supplies and connect them to separate wall sockets.
Note: NetScaler appliances emit a high-pitched alert if one power supply fails or if you connect only one power cable to an appliance in which two power supplies are installed. To silence the alarm, press the small red button on the back panel of the appliance. The disable alarm button is functional only when the appliance has two power supplies.

To install a hard disk drive
  1. At the NetScaler command prompt, exit to the shell prompt. Type:

    shell

  2. Shut down the NetScaler appliance by typing one of the following commands at the shell prompt.
    • On an MPX appliance, type:

      shutdown –p now

    • On a non-MPX appliance, type:

      shutdown

  3. Locate the hard disk drive on the back panel of the appliance.
  4. Verify that the replacement hard disk drive is the correct type for the NetScaler platform.
  5. Disengage the hard disk drive by pushing the safety latch of the drive cover to the right or down, depending on the platform, while pulling out on the drive handle to disengage. Pull out the faulty drive.
