The NetScaler SDX 25100 40G, SDX 25160 40G appliances have 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 0/1and 0/2 from left to right. These ports are used to connect directly to the appliance for system administration functions.
- Network Ports: Four 40G QSFP+ ports and sixteen 10G SFP+ ports (4x40G QSFP+ + 16x10G SFP+). For information about supported transceivers per port, see 25G, 40G, 50G, and 100G ports.
- USB ports (reserved for a future release).
Note:
- 10G ports do not support 1G copper or 1G fiber transceivers.
- 40G ports do not support 10G and 1G transceivers.

The following components are visible on the back panel of the SDX 25100-40G, SDX 25160-40G appliance:
-
Two 300 GB removable solid-state drives (SSDs). The two leftmost solid-state drives store the NetScaler software. The next two solid-state drives, of 300 GB each, store user data. The remaining four solid-state drives are reserved for future use.
Note: Drive densities might increase as components become EOL but its size is never smaller than the original.
- Power switch. Which turns power to the appliance on or off? Press the switch for less than two seconds to shut off the power.
- Two power supplies. Each rated at 1000 watts, 100–240 volts. Each power supply has an LED that indicates the status of the power supply, as described in Common Hardware Components](/en-us/netscaler-hardware-platforms/sdx/common-hardware-components.html).
- Disable alarm button. Which is functional only when the appliance has dual redundant, hot-swappable power supplies. Press this button to silence the power alarm when one of the two power supplies loses input power or when a power supply is malfunctioning.
- 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.
