    Description

    A fully-functional miner setup, as previously used by seller. Includes everything needed, other than an appropriate wall outlet.
    Miners
    -  Eight Antminer S9's. Clean and in good working order. Ran Slush Pool's Braiins OS+ with the same hardware included.
    5 x Dual - Miner PSU
    -  Five power supplies that each run two miners. Require 220V and provide up to 2400W each. 80PLUS Platinum certified for 94% efficiency. Connect to miners with the black-and-white ATX cables and PCIE breakout boards pictured. They are the same units that previously powered the miners. For reference, they are also available on parallelminer.com, as part of a kit with item number KT-2400CUSTOM. Only four PSU's are needed - fifth is new/unused spare.
    PSU - to - Miner Cables
    -  All the ATX cables and breakout boards needed for each PSU.
    30 - Amp PDU
    -  A new/unused J542N server PDU, identical to the one that previously fed all eight miners. Four sockets, for four PSU's, for eight miners. Needs 208 - 240V from a wall outlet and provides up to 30 amps. It can power all eight miners if they are set in software to draw no more than 800W apiece. If the miners are to be run at or near their nominal maximum draw of about 1400W, then this PDU will feed four at most. It has a ten-foot cord with a NEMA L6-20 plug.
    8 x PSU - to - Power Cable
    -  New/unused power cables for connecting PSU's to PDU. Four six-foot and four one-foot. Each PSU needs one. Extras for cable management. 'C19' plug at the PSU end and 'C20' at the other.
    1 x 24 - Port Network Switch
    -  TRENDnet TEG-S24g network switch. 10/100/1000 Mbps ethernet, 48 Gbps total switching capacity. Can accommodate more than twenty miners.
    30 x CAT6 Ethernet Cables
    -  10 x 3' , 10 x 5' , 5 x 7' , 5 x 10' . Each miner requires only one - extras are for cable management. Throughput and shielding specifications of the CAT6 standard greatly exceed the requirements of Bitcoin mining. Frequencies up to 250 MHz and lengths up to 180 ft. are supported.
    3 x Ethernet Couplings
    -  Connect one ethernet cable to another, effectively creating one long cable.
    SD Card and Reader
    -  512MB micro SD card (S9's do not reliably recognize SD cards with capacity greater than 2GB), an SD adapter, and a simple USB card reader. SD card can be used to load an OS onto any number of miners. An OS can also be loaded via the network connection, but the SD-card method may be more-reliable under some circumstances.
    C19 Repair Cable
    -  An additional C19 power cable with bare copper wires at the free end. For testing alternative plugs and hardwired arrangements.
    ---  SHIPPING  ---
    From mid-Missouri, to the continental US, by FedEx Ground. Buyer will receive the same packages pictured. Please examine all packages before opening, as returns for these items will be nearly-impossible to accept after the packages are opened. A signature from an adult (21+) will be required for each package at delivery - providing a signature asserts that the package is in acceptable condition. Do not sign for a package if it appears damaged in any substantial way. A package not signed-for will be returned to the seller at no expense to the buyer, after which the buyer may choose between another shipment or a refund.
    ---  HELP  ---
    Any help asked-for will be given before and after purchase, including use advice and item and shipment details. Please ask any and all questions, especially before purchasing.
    ---  CLAIMS AND RECEIVING ---
    Please photograph each package from various angles at delivery, regardless of condition. Please also photograph all contents, and especially any package or object which arrives damaged, whether accepting it or not. It is not necessary to send these pictures to us, or to FedEx, except in the case of damage, possible damage, or a functional problem; but addressing any problem that occurs as a result of shipping will only be possible if comprehensive photos can be provided.
    ---  RETURNS  ---
    Conducting a return for miners that have been
    opened
    will be almost impossible - because of the real expense, because of the excruciating inconvenience, and because an attempt by a buyer to pack the miners for safe return shipment would incur enough additional risk to invalidate the effort that we put into same; but mostly because of the tampering with ASIC miners which becomes possible when shipping them to buyers who are permitted to open, handle, and then return them. A "Developer Fee," or "Dev Fee," for example, is code that can be added to a miner's firmware, which causes the miner to perform a fraction of its hashing time for the writer of the code, rather than the owner of the unit. We would not be able to fix something like this if it were done to one of our units. It would also be impossible to guarantee that a miner from an opened package had been handled gently-enough to avoid damage. Please understand; and thank you.
