Depending on the model, the appliance has the following ports:

  • RS232 serial Console Port.
  • 10/100Base-T copper Ethernet Port (RJ45), also called the LOM port. You can use this port to remotely monitor and manage the appliance independently of the NetScaler software.
  • Two 10/100/1000Base-T copper Ethernet Management Ports (RJ45), numbered 0/1 and 0/2 from left to right. These ports are used to connect directly to the appliance for system administration functions.
  • Network Ports
    • SDX 24100/24150 (12x1G SFP + 24x10G SFP+). Twelve copper or fiber 1G SFP ports and twenty-four 10G SFP+ ports.

The following components are visible on the back panel of the SDX 24100/24150 appliance:

  • Non-maskable interrupt (NMI) Button, used at the request of Technical Support to initiate a core dump. To press this red button, which is recessed to prevent unintentional activation, use a pen, pencil, or other pointed object. The NMI Button is also available remotely over the network in the LOM GUI, in the Remote Control menu.
  • System status LED, which indicates the status of the appliance, as described in LCD Display and LED Status Indicators.

    Note: On an SDX 24100/24150 appliance running LOM firmware version 3.22, the system status LED indicates an error (continuously glows RED) even though the appliance is functioning properly.
  • Four power supplies, each rated at 750 watts, 100-240 volts. A minimum of two power supplies are required for proper operation. The extra power supplies act as backup. Each power supply has an LED that indicates the status of the power supply, as described in LCD Display and LED Status Indicators.
  • Power switch, which turns off power to the appliance. Press the switch for less than two seconds to turn off the power.
  • Four 600 GB removable solid-state drives. The first two leftmost solid-state drives store the NetScaler software. The next two solid-state drives store user data. Additionally, you can extend the SSD storage (optional) by another 2 or 4 600 GB SSDs.
