Troubleshooting Power Supply/Cooling Fan Module

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

CAUTION: It is recommended that you turn off the host server before turning off the array to prevent loss of data.

1Locate the faulty power supply and determine the status of the LEDs.

•If the AC power LED is not lit, check the power cord and power source into which the power supply is plugged.

•Connect another device to the power source to verify if it is working.

•Connect the cable to a different power source.

•Replace the power cable.

If the problem is not resolved, see "Getting Help" on page 259.

•If the DC power LED is not lit, verify that the power switch is turned on. If the power switch is turned on, see step 2.

•If the power supply’s fault indicator is lit, see "Getting Help" on page 259.

CAUTION: Power supply/cooling fan modules are hot-swappable. The array can operate on a single power supply; however both modules must be installed to ensure proper cooling. A single power supply/cooling fan module can be removed from a powered-on array for a maximum period of five minutes. Beyond that time, the array may automatically shut down to prevent damage.

2Reseat the power supply by removing and reinstalling it. See "Power Supply and Cooling Fan Features" on page 29.

NOTE: After installing a power supply, allow several seconds for the array to recognize the power supply and to determine if it is working properly.

If the problem is not resolved, see "Getting Help" on page 259.

MD3200i, MD3220i specifications

The Dell MD3220i and MD3200i are part of Dell's extensive line of modular storage solutions, designed to support organizations in optimizing their data management and scalability requirements. These models offer reliable performance and flexible features, making them suitable for various workloads including virtualization, cloud storage, and disaster recovery.

One of the standout features of the MD3220i and MD3200i is their support for iSCSI storage networking. By utilizing the Internet Small Computer Systems Interface (iSCSI) protocol, these systems provide organizations with a cost-effective way to connect their storage over existing network infrastructure, enabling efficient data transfers and management.

Both models are equipped with dual controllers that ensure high availability and failover capabilities, which are crucial for meeting uptime requirements in mission-critical environments. The dual controllers also facilitate load balancing and increase overall system performance, as they allow multiple paths to the storage, enhancing I/O performance.

Scalability is another key characteristic of the MD3220i and MD3200i. These storage arrays can be expanded to meet growing storage demands, supporting up to 240TB of raw capacity with up to 16 additional expansion enclosures. This flexibility allows organizations to start with a smaller configuration and grow their storage capabilities without a complete overhaul of the existing infrastructure.

The units also support multiple disk types, including traditional spinning disks, solid-state drives (SSDs), and a combination of both. This versatility enables users to tailor storage configurations to their specific performance and budgetary needs. Furthermore, the systems feature advanced data management technologies such as snapshots and remote replication, providing essential tools for data protection.

With their ease of management, the MD3220i and MD3200i are designed for straightforward configuration and operation. The intuitive management interfaces allow IT professionals to monitor performance, configure storage, and manage data effectively, ensuring businesses can maintain optimal system availability.

In summary, the Dell MD3220i and MD3200i are robust, scalable, and versatile storage solutions that cater to diverse organizational needs. Their integrated technologies, such as iSCSI support, dual controller architecture, and advanced data management features, make them an ideal choice for modern data centers looking to enhance storage capabilities while ensuring reliability and performance.
