Table 1. Features are available on the front of the systemItem 1 is the left control panel, contains system health and system ID, status LED, and optional iDRAC Quick Sync 2 (wireless) indicators. The status LED enables you to identify any failed hardware components. The Quick Sync 2 enables management of the system by using mobile devices. Item 2 is the optical drive (optional), contains one optional slim SATA DVD-ROM drive or DVD+/-RW drive. Item 3 is the video connector, which enables you to connect a display device to the system. Item 4 is the right control panel, contains the power button and USB port, iDRAC Direct micro port, and the iDRAC Direct status LED. Item 5 is hard drive slots, which enables you to install hard drives that are supported on your system.

Table 2. Features available on the front of the systemThis table describes the features available on the sled
Item	Ports, panels, and slots	Icon	Description
1	DSFF OCP slot 1	N/A	The OCP NIC card supports OCP 3.0. The NIC ports are integrated on the OCP card which is connected to the HPM board
2	DSFF OCP slot 2	N/A	The OCP NIC card supports OCP 3.0. The NIC ports are integrated on the OCP card which is connected to the HPM board
3	ePPS SMA module	N/A	This is a coaxial connector used for timing inputs/outputs.
4	GNSS module (optional)	N/A	Delivers precise location and time synchronization for devices..
5	Information tag	N/A	The Information tag is a slide-out label panel that contains system information such as Service Tag, NIC, MAC address, and so on. If you have opted for the secure default access to iDRAC, the Information tag also contains the iDRAC secure default password.
6	Floating SFP28 module	N/A	4 x SFP28 25 GbE ports on the floating module
7	USB - C port	N/A	Allows you to connect USB C devices to the system and can be used for iDRAC direct management
8	Co-planar SFP28 module	N/A	4 x SFP28 25 GbE ports on the co-planar module
9	System identification button		The System Identification (ID) button is available on the front of the system. Press the button to identify a system in a rack by turning on the system ID button. You can also use the system ID button to reset iDRAC and to access the BIOS using the step-through mode. When pressed, the system ID LED in the front panel blinks until the front button is pressed again. Press the button to toggle between on or off mode. The following are the LED behaviors: No light - System is in the off state (S5, or mechanical (AC power not applied) OFF) Blinking Amber - System fault/error condition. Steady Blue - Normal operating state (S0) Blinking Blue - System ID engaged. (See System ID button description below) Any system error could drive this LED, the implementation is system dependent. This LED remains powered during nonoperational (standby, shutdown) modes, to enable system identification. NOTE:If the server stops responding during POST, press and hold the System ID button for more than five seconds to enter the BIOS progress mode. NOTE:To reset the iDRAC (if not disabled on the iDRAC setup page by pressing F2 during system boot), press and hold the System ID button for more than 15 seconds.
10	Sled handle	N/A	Enables you to remove the sled from the enclosure.
11	Sled power button	N/A	Enables you to power on the sled. Indicates if the system is powered on or off. Press the power button to manually power on or off the system. The Power LED has two states: Power LED is off: System is not operating, regardless of AC present. (Other AUX powered subsystems may be operational with AC power present.) Power LED is on (Green): System is operating. One or more of the non-standby (Vaux) power rails are active. Specific implementation of what signal drives the LED is left to the system designer NOTE:When XR8720t is installed in the XR8000r chassis, the power button LED indicator status may be delayed for up to two minutes while the sled is initializing. The power button LED will start slowly blinking to indicate the system is performing the power on sequence after this time period.
12	Mini-DisplayPort		Enables you to connect a display device to the system.
13	Heater LED		The Heater LED explains the heater status of the chassis. The LEDs have a bi -color property: they can display a green or amber status. NOTE:LED lights Green when system pre‐heating is enabled and will turn off when system pre‐heating is completed. The heater manager will continue to maintain the proper temperature on the system after preheating, but the LED will stay off while the system is on. NOTE:LED flashes Amber with a 1 Hz frequency when any required heater or thermal sensor is absent or has failed.
14	RJ45 Dry Input	N/A	It is an RJ45 Dry Input port. Enhance penetration in the IoT space. These are interruptible inputs to iDRAC. Dry means that no energy is supplied to the contacts.
15	USB A port		Host port lets you connect USB A devices to the system.
16	iDRAC RJ45 dedicated port		Enables you to remotely access iDRAC. For more information, see the Integrated Dell Remote Access Controller User's Guide at PowerEdge Manuals.
