卸下电源设备单元

卸下交流和直流 PSU 的步骤是相同的。

前提条件

警告:系统正常运行时需要一个电源设备 (PSU)。在电源冗余系统中，每次只在电源开启的系统中卸下并更换一个 PSU。
  1. 按照“安全说明”中所列的安全原则进行操作。
  2. 断开电源缆线与要卸下的电源和 PSU 的连接，然后从 PSU 手柄上的紧固带上拔出缆线。
  3. 如果可选的缆线固定臂妨碍您卸下 PSU，则打开闩锁并将其提起。

    有关电缆固定臂的信息，请参阅系统机架文档，网址：www.dell.com/poweredgemanuals。

步骤

按压桔色释放闩锁并使用 PSU 手柄将 PSU 滑出系统。
