Setting up the Server

Configuring the Server
Setting up the Pool To configure the server:

1. Click Settings marked below. Note:
   • Fan speed percentage can be adjusted, but we recommend to keep the default setting. The server will adjust the fan speed automatically if the fan speed percentage has yet been selected.
   • There are two working modes of K7 server: Normal mode and Sleep mode. The server enters the sleep mode under the condition that the control board is powered while hashboards are not powered.
2. Set the options according to the following table:
   Option| Description
   ---|---
   Mining address| Enter the address of your desired pool.

The K7 servers can be set up with three mining pools, with decreasing priority from the first pool (pool 1) to the third pool (pool 3). The pools with low priority will only be used if all higher-priority pools are offline.

Name| Your worker ID on the selected pool.
Password (optional)| The password for your selected worker.
3. Click Save after the configuration.

Monitoring Your Server
To check the operating status of your server:

1. Click the dashboard marked below to check the server status (taking K7-63.5T as an example).
2. Monitor your server according to the descriptions in the following table:
   Note: The K7-63.5T server is with a fixed frequency of 665 MHz. Firmware will stop running when the Temp (Outlet) reaches to 95℃，there will be an error message “high temp exceed limit (Overtemperature duration/s), max_chip_temp = (chip-real-temperature), max_pcb_temp = (board-real-temperature)!” shown on the bottom of kernel log page. Meanwhile, the server temperature on the dashboard interface turns abnormal and shows “Temp is too high”.
