1.6 Backpane
The backside of the QOS hosts all the adapters, Ethernet, Fibre Channel, 10GigE, power,
diagnostic VGA and USB cables. Data ports such as Ethernet and Fibre Channel have
green activity lights that indicate a healthy connection. On the back of the QOS there is a
small power button, which can be used to initialize and shut down the device; when the
activity lights on the front panel go out the unit is fully shut down. Some models have a
0/1 power switch on the back panel sends power to the power supply and should be shut
off before unplugging the unit, and needs to be turned on (‘1’ position) before powering
on.
1.7 Drive Replacement
There are eight hot swappable enterprise grade Seagate 1, 2, or 3TB drives in the QOS 8-‐
Bay system. These drives feed information to the QOS 8 System from the drive firmware
such as factory information, total read/write errors, and temperature. In RAID6 mode
(the QOS can also stripe as RAID0), two drives can fail on the system without losing any
data. The drive that has failed will immediately be marked with a red light on the front
