IO Ports

IPMI dedicated LAN port. The Intelligent Platform Management Interface (IPMI) 2.0 architecture provides a command line interface to the Baseboard Management Controller (BMC) on the 500NX 1U motherboard. IPMI is a standardized protocol used to manage and monitor a system in-band or out-of-band. As a result, IPMI operates independently of the host OS and interfaces directly with the hardware. IPMI allows a system administrator to monitor system health and manage computer events from a remote location. IPMI provides features for monitoring, logging, recovery, and inventory control through hardware and firmware. These functions are provided independent of the main CPU, BIOS, and OS.

VGA port. The GPUs process complex image calculations and then route the data out through the VGA port on the motherboard. A jumper on the motherboard can be set to disable the VGA port.

Front Control Panel Buttons and LEDs

Power. The main power switch applies or removes primary power from the power supply to the server but maintains standby power. Unplug the server to remove all power.

BMC reset and UID. This button has a dual function, depending on the JBMC_BTN jumper. This button is recessed from the front of the server. The UID LED is embedded inside the button. Use a pointed object, such as a pen or a paper clip to push the button. The BMC reset button either: Turns on or off the blue UID light that is used to visually identify a specific server installed in the rack or among several racks/cabinets. Resets the BMC that provides IPMI support.

System Reset Button/Information LED System Reset Button. The reset button is used to reboot the server. This button is recessed from the front of the server. Use a pointed object, such as a pen or a paper clip to push the button. Information LED. Alerts operator to several states, as noted in the table below. The LED is embedded inside the button.

Table 1. CS-Storm 500NX 1U Status LEDs

Information LED Status	Description
Red (solid on)	An overheat condition has occurred. (This may be caused by cable congestion.)
Red (blinking - 1 Hz)	Fan failure, check for an inoperative fan.
Blue (solid on)	Local UID has been activated. Use this function to locate the server in a rackmount environment.
Blue (blinking)	Remote UID is on. Use this function to identify the server from a remote location.

I/O Connector LEDs

LAN LED Indicators. The activity LED indicates network connection when on, and transmit∕receive activity when blinking. The color of the link/speed LED indicates the data transfer speed. The following table provides an overview of the LEDs.

LAN Port Symbols. There are two symbols that provide status information about the LAN ports.

NIC 1. When flashing, indicates network activity on GLAN1.

NIC 2. When flashing, indicates network activity on GLAN2.

Power Supply LEDs

An LED on the rear of the power supply unit displays the status.
