1211 Front Panel Controls and I/O Panel

CS500 model 1211 controls I/O panel LEDs.

The 1211 server includes a control panel that provides push-button system controls and LED indicators for several system features. Depending on the drive configuration, the front control panel may come in either of two formats; however, both provide the same functionality.

Figure: CS500 Model 1211 Front Panel Controls and Indicators

System ID button: Toggles the integrated ID LED and the blue motherboard ID LED on and off. The system ID LED is used to visually identify a specific server installed in the rack or among several racks of servers. The system ID LED can also be toggled on and off remotely using the IPMI chassis identify command which causes the LED to blink for 15 seconds.

NMI button: When the non-maskable interrupt (NMI) button is pressed, it puts the server in a halt state and issues an NMI. This can be useful when performing diagnostics for a given issue where a memory download is necessary to help determine the cause of the problem. To prevent an inadvertent system halt, the actual NMI button is recessed from the front panel where it is accessible only with a small tipped tool like a pin or paper clip.

NIC activity LEDs: An activity LED is included for each onboard network interface controller (NIC). When a network link is detected, the LED turns on solid. The LED blinks consistently while the network is being used.

System cold reset button: Pressing this button reboots the reinitializes the system.

System Status LED: This LED lights green or amber to indicate the current health of the server. This feature is also provided by an LED on the back edge of the motherboard. Both LEDs are tied together and show the same state. The System status LED states are driven by the on-board platform management subsystem. A description of each LED state for the server follows.

Table 1. CS500 Model 1211 System Status LEDs
LED State	Criticality	Description
Off	Not ready	System is powered off (AC and/or DC) System is in Energy-using Product (EuP) Lot6 Off mode/regulation¹ System is in S5 Soft-off state.
Green solid	OK	Indicates the system is running (in S0 state) and its status is Healthy. There are no system errors. AC power is present and the BMC has booted and management is up and running. After a BMC reset with a chassis ID solid on, the BMC is booting Linux. Control has been passed from BMC uboot or BMC Linux. It will be in this states for 10-20 seconds.
Green blinking 1Hz	Degraded - system is operating in a degraded state although still functional, or system is operating in a redundant state but with an impending failure warning	System degraded: Power supply/fan redundancy loss Fan warning or failure Non-critical threshold crossed (temperature, voltage, power) Power supply failure Unable to use all installed memory Correctable memory errors beyond threshold Battery failure Error during BMC operation
Amber solid	Critical, non-recoverable - system is halted	Fatal alarm - system has failed or shutdown
Amber blinking 1Hz	Non-critical - system is operating in a degraded state with an impending failure warning, although still functioning	Non-fatal alarm - system will likely fail Critical threshold crossed (temperature, voltage, power) Hard drive fault Insufficient power from PSUs Insufficient cooling fans
1. The overall power consumption of the system is referred to as System Power States. There are a total of six different power states ranging from S0 (the system is completely powered ON and fully operational) to S5 (the system is completely powered OFF) and the States (S1, S2, S3 and S4) are referred to as sleeping states

Drive activity LED: This LED indicates drive activity from the on-board storage controllers. The motherboard also provides a header to give access to this LED for add-on controllers.

Power/sleep button: This button toggles the system power on and off. Pressing this button sends a signal to the BMC, which either powers the system on or off. This button also functions as a sleep button if enabled by an ACPI compliant operating system. The integrated LED is a single color (Green) and is capable of supporting different indicator states as defined in the following table.

Table 2. CS500 Model 1211 Power Button Status LEDs
State	Power Mode	LED	Description
Power-off	Non-ACPI	Off	System power is off, and the BIOS has not initialized the chipset.
Power-on	Non-ACPI	On	System power is on.
S5	ACPI	Off	Mechanical is off and the operating system has not saved any context to the hard disk.
S0	ACPI	On	System and the operating system are up and running.

I/O Panel Features

Systems configured with eight 3.5in hard drive bays or up to sixteen 2.5in hard drive bays will also include an I/O Panel providing additional system I/O features.

Figure: CS500 Model 1211 Front I/O Panels

Video connector: A monitor can be connected to the video connector on the front I/O panel. When BIOS detects that a monitor is attached to this video connector, it disables video signals routed to the video connector on the back on the chassis. Video resolution from the front connector may be lower than from the rear on-board video connector. A short video cable should be used for best resolution. The front video connector is cabled to a 2x7 header on the server board labeled FP Video.

USB 2.0/3.0 Ports: The front I/O panel includes two USB 2.0/3.0 ports. The USB ports are cabled to a blue 2x5 connector on the server board labeled FP_USB.; Due to signal strength limits associated with USB 3.0 ports cabled to a front panel, some marginally compliant USB 3.0 devices may not be supported from these ports.
