Avalon6

Basic Information

Hashrate:
    3.5T (+-5%)

Power consumption:
    990W (measure on 12V port of the device)
    1100W (on the wall, with assumption of 90% power conversion ratio)

Power per hash:
    270J/THash (device only)
    295J/THash (on the wall, with assumption of 90% power conversion
ratio)

Overclocking:
    Support automatically optimize frequency, no need to overclock manually.

PSU output pin:
    4x6PIN PCIe power connector. *All must be connected.*

PSU requirements:
    Minimum 1100W output, recommend to use high-quality PSU for server
with more than 1200W output and high quality power cable.
    Input voltage no lower than 11.7V and no higher than 12.2V (numbers
take from the controller)
    Lower voltage leads to lower hashrate and higher voltage leads to
possible device burning down.
    NOTICE: Poor quality cable may result in low voltage.

Fan:
    Specs: 12038
    Current: between 1.6A and 2.8A.
    Minimum RPM: 3800.
    *NOTICE* If the fan is broken or the fan's RPM cannot be measure,
the device will not start.

Controller:
    Raspberry Pi (version B or B+)
    Raspberry Pi 2 will be supported at the middle of December 2015
    Each Rpi can control approximately ~12 devices.

AUC:
    Each AUC can connect up to 6 devices.

Dimensions:
    354x136x150mm

Net weight:
    ~4.8kg

Protection Degree:
    IP20

TYPE meaning:

 WARN-It designates potentially harmful situations, but you can ignore it.
 FATAL-It designates very severe error events that will presumably lead the Avalon6 to crash.

TODO

OpenWrt

1. Support Raspberry Pi 2B
2. Update with the master branch
3. Support Avalon6 in LuCI (Advanced version)
4. Keep more coding on LuCI (Avalon theme)

CGMiner

1. Add auto speed option
2. Merge the Avalon6 code to CK's master

Known Issues

1. MM can be upgrade by mismatch firmware.
2. local hashrate (GHS av) cann't match with the pool's hashrate
3. Use 5 or more modules in one AUC will cause MM idle periodically.
4. Duplicate MM address

FAQ

1. How to deal with the red blinking machine?

2. How to boot the machine or hashboard unit safely?
