Instructions for replacing the P13 power cord for Antminer S21 S19jXP

Designed specifically for Antminer S21 / S19j XP miners, this P13 4-pin plug cable, with a length of 150 cm, it is used with Antminer APW17 power supply. It perfectly fits the PSU interface of the miner and supports multiple plugs (C20 / US / UK / EU / P33 / AU). The high-quality P13 power cord provides stable power transmission for Antminer S21 and S19j XP, ensuring their stable operation under high loads and reducing shutdowns and restarts caused by power issues.

A faulty P13 power cable can cause power transmission interruptions or instability for Antminer S21 and S19j XP, leading to frequent restarts or direct shutdowns. Long-term power instability may damage the internal hardware of the miner, shortening its lifespan and affecting its normal operation.

How to replace the power cord?

1. Ensure that the miner and power supply unit are completely powered off to prevent electric shock and equipment damage.

2. Carefully unplug the faulty P13 power cable and check the interface for any damage or dirt. Additionally, inspect the internal components of the miner for abnormalities to ensure the power cord won't be damaged again. Replace any worn-out parts if necessary.

3. Confirm that the new P13 power cord is not damaged, broken, exposed wires, etc., and the connector is clean.

4. Plug one end of the new P13 power cord into the PSU interface, and the other end (C20 / US / UK / EU / P33 / AU) into the PDU. Ensure the connections are secure and free from looseness or poor contact.

5. Turn on the PDU power first, then start the miner and check for normal operation.

6. Observe the miner's operating status and hash rate to ensure there are no abnormalities or performance degradation.

Note: Please check and protect the power cable during daily use. Common causes of damage include shorts or poor contact due to excessive voltage, excessive current, and circuit aging. Long-term excessive pulling, bending, or frequent plugging and unplugging can also damage the power cord. Keep the plug clean to avoid poor contact.

Replacing the P13 power cord for Antminer S21 and S19j XP restores stable power to the miner, helping improve equipment stability and hash rate, extend its lifespan, reduce maintenance costs and downtime, and ensure continuous mining profitability.
