Attention

This type of power supply is hot-swap only when two power supplies are installed for redundancy. If only one power supply is installed, you must power off the server first before removing the power supply.

The following tips describe the information that you must consider when you remove a power supply with dc input.

CAUTION

240 V dc input (input range: 180-300 V dc) is supported in Chinese Mainland ONLY. Power supply with 240 V dc input cannot support hot plugging power cord function. Before removing the power supply with dc input, please turn off server or disconnect dc power sources at the breaker panel or by turning off the power source. Then, remove the power cord.

在直流输入状态下，若电源供应器插座不支持热插拔功能，请务必不要对设备电源线进行热插拔。此操作可能导致设备损坏及数据丢失。因错误执行热插拔导致的设备故障或损坏，不属于保修范围。

NEVER CONNECT AND DISCONNECT THE POWER SUPPLY CABLE AND EQUIPMENT WHILE YOUR EQUIPMENT IS POWERED ON WITH DC SUPPLY (hot-plugging). Otherwise you may damage the equipment and result in data loss, the damages and losses result from incorrect operation of the equipment will not be covered by the manufacturers’ warranty.

To remove a hot-swap power supply, complete the following steps:

Watch the procedure

A video of this procedure is available at YouTube.

1. If the server is in a rack, adjust the cable management arm (CMA) to gain access to the power supply.
   If you have installed the 1U CMA Upgrade Kit for Toolless Slide Rail or Toolless Slide Rail Kit with 1U CMA, do the following:

   Figure 2. CMA adjustment
   

   

   
   
   1. Press down the stop bracket 1 and rotate it to the open position.
   2. Rotate the CMA out of the way to gain access to the power supply.
2. Disconnect the power cord from the hot-swap power supply.
   Note

   If you are replacing two power supplies, do the power supply replacement one by one to ensure that the power supply to the server is not interrupted. Do not disconnect the power cord from the secondly replaced power supply until the power output LED for the firstly replaced power supply is lit. For the location of the power output LED, refer to Rear view LEDs.
3. Press the release tab toward the handle and carefully pull the handle at the same time to slide the hot-swap power supply out of the chassis.
   Note: Slightly pull the power supply upwards when sliding the power supply out of the chassis, if you have installed one of the following CMA kits:

   • 1U CMA Upgrade Kit for Toolless Slide Rail

   • Toolless Slide Rail Kit with 1U CMA
