Storage controller features and indicators

Item	Control/Feature	Icon	Description
1	I/O card slot		Fibre Channel I/O card – Ports are numbered 1 to 4 from left to right The LEDs on the 16 Gb Fibre Channel ports have the following meanings: All off – No power All on – Booting up Blinking amber – 4 Gbps activity Blinking green – 8 Gbps activity Blinking yellow – 16 Gbps activity Blinking amber and yellow – Beacon All blinking (simultaneous) – Firmware initialized All blinking (alternating) – Firmware fault The LEDs on the 32 Gb Fibre Channel ports have the following meanings: All off – No power All on – Booting up Blinking amber – 8 Gbps activity Blinking green – 16 Gbps activity Blinking yellow – 32 Gbps activity Blinking amber and yellow – Beacon All blinking (simultaneous) – Firmware initialized All blinking (alternating) – Firmware fault iSCSI I/O card – Ports are numbered 1 to 4 from left to right NOTE: The iSCSI I/O card supports Data Center Bridging (DCB), but the mezzanine card does not support DCB. The LEDs on the iSCSI ports have the following meanings: Off – No power Steady Amber – Link Blinking Green – Activity SAS I/O card – Ports are numbered 1 to 4 from left to right The SAS ports on SAS I/O cards do not have LEDs.
2	Identification LED		Blinking blue continuously – A command was sent to the storage system to make the LED blink so that you can identify the storage system in the rack. The identification LED blinks on the control panel of the chassis, which allows users to find the storage system when looking at the front of the rack. The identification LEDs on the storage controllers also blink, which allows users to find the storage system when looking at the back of the rack.
3	Cache to Flash (C2F)		Off – Running normally Blinking green – Running on battery (shutting down)
4	Health status		Off – Unpowered Blinking amber Slow blinking amber (2s on, 1s off) – Controller hardware fault was detected. Use Storage Manager to view specific details about the hardware fault. Fast blinking amber (4x per second) – Power good and the pre-operating system is booting Blinking green Slow blinking green (2s on, 1s off) – Operating system is booting Blinking green (1s on, 1s off) – System is in safe mode Fast blinking green (4x per second) – Firmware is updating Solid green – Running normal operation
5	Serial port (micro USB)		Used under the supervision of technical support to troubleshoot and support systems.
6	MGMT port	—	Ethernet port used for storage system management and access to Storage Manager. Two LEDs with the port indicate link status (left LED) and activity status (right LED): Link and activity indicators are off – Not connected to the network Link indicator is green – The NIC is connected to a valid network at its maximum port speed. Link indicator is amber – The NIC is connected to a valid network at less than its maximum port speed. Activity indicator is blinking green – Network data is being sent or received.
7	USB port		One USB 2.0 connector that is used for SupportAssist diagnostic files when the storage system is not connected to the Internet.
8	Mini-SAS (ports 1 and 2)		Back-end expansion ports 1 and 2. LEDs with the ports indicate connectivity information between the storage controller and the expansion enclosure: Steady green indicates the SAS connection is working properly. Steady yellow indicates the SAS connection is not working properly.
9	Mezzanine card		The iSCSI ports on the mezzanine card are either 10 GbE SFP+ ports or 1 GbE/10 GbE RJ45 ports. The LEDs on the iSCSI ports have the following meanings: Off – No connectivity Steady green, left LED – Link (full speed) Steady amber, left LED – Link (degraded speed) Blinking green, right LED – Activity NOTE: The mezzanine card does not support DCB.
