CK BOX II authenticated modes
Default: 2.1 TH/s +/-5%, 400 W +/-5%, OEM-rated 190 J/TH. Low: 1.54 TH/s +/-5%, 260 W +/-5%, OEM-rated 169 J/TH. These are discrete manufacturer modes; default mode is the comparison operand.
Correct physical and environmental boundary
Machine dimensions are 150 x 198 x 96 mm and net weight is 2.2 kg. Package dimensions are 300 x 220 x 142 mm and gross weight is 2.7 kg. The manufacturer rates noise at no more than 35 dB, ambient at 0-35 C and relative humidity at no more than 65%. Ethernet and Wi-Fi are supported; fan speed is listed at 4500 rpm.
Electrical boundary
The miner accepts 12 V DC and uses an external PSU. The manufacturer table labels the power cable 10 A; that is not facility AC input or universal equipment current. Facility voltage, plug, branch circuit and protection come from the exact selected PSU. Base CK-BOX accessory information, including a 300 W PSU, must not be imported into this 400 W BOX II generation.
Firmware and internal temperature
The exact official artifact is firmware-Goldshell-CKBoxII-2.2.2.cpb. Base CK-BOX uses a different 2.2.7 artifact and controller family; never cross-flash by name resemblance. Manufacturer internal readings distinguish CK BOX II normal 78 C and protection 86 C from base CK-BOX values; these are internal readings, not ambient limits.
