Deployment Guide

Item Control/Feature Icon Description
• 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.
