Action

CAUTION: Only trained service technicians are authorized to remove the enclosure cover and access any of the components inside the enclosure. Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the enclosure and protecting against electrostatic discharge.

NOTICE: It is recommended to power down the server before powering down the enclosure to prevent loss of communication.

1Check that at least two drives are present in the enclosure. A minimum of two drives must be installed. If they are not, install the minimum number of drives. If the problem persists, go to step 2.

2Locate the faulty power supply and determine the status of the LEDs.

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

Use a known good power source (outlet).

Use a known good power cord.

If the DC power LED is not lit, verify that the power switch is turned on. If the power switch is turned on, continue to step 3.

If the power supply's fault indicator is lit, continue to step 3.

NOTICE: Power supply/cooling fan modules are hot-pluggable. The enclosure can operate on a single functioning power supply; however, both modules must be installed to ensure proper cooling. A single power supply/cooling fan module can be removed from the enclosure for up to 5 minutes, provided the other module is functioning properly. After 5 minutes, the enclosure will overheat and may cause an automatic thermal shutdown.

3Ensure that the power supply is properly installed by removing and re-installing it. See "Removing and Installing the Power Supply/Cooling Fan Module."

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

4If the problem persists, see "Getting Help."

MD1000 specifications

The Dell MD1000 is a storage enclosure designed to provide a scalable and reliable solution for enterprises seeking efficient data storage management. Recognized for its robust performance and versatility, the MD1000 supports a variety of applications, making it a popular choice among organizations that demand high-capacity storage solutions.

One of the standout features of the MD1000 is its modular design, allowing it to integrate seamlessly with various Dell server systems. It provides efficient data storage through its 3.5-inch drive bays, accommodating up to 15 hard drives or solid-state drives. This configuration not only facilitates higher storage density but also supports SATA and SAS drives, offering the flexibility to choose different types of storage media based on organizational needs.

The MD1000 features advanced RAID (Redundant Array of Independent Disks) technology, which enhances data protection and system performance. It supports multiple RAID levels, including RAID 0, 1, 5, 6, and 10, providing users with different options for balancing performance and redundancy. By leveraging RAID, the MD1000 ensures that data remains safe and accessible even in the event of hardware failure, significantly reducing downtime and risk.

Connectivity is another strength of the MD1000. It typically interfaces with a server through a variety of host interface options including iSCSI and Fibre Channel, making it adaptable to different network configurations. This connectivity flexibility supports various environments, ensuring organizations can scale their storage without significant infrastructure overhauls.

Cooling and power efficiency are also critical characteristics of the MD1000. It includes dual-redundant power supplies and cooling fans that not only enhance reliability but also lower operational costs. These components can function independently, ensuring that power loss in one does not affect overall system performance.

Management and monitoring capabilities of the MD1000 are empowered by the Dell OpenManage software, which provides a user-friendly interface to manage the storage subsystem. Users can easily monitor drive health, configure RAID settings, and receive alerts on potential issues, simplifying the administration of large storage networks.

Overall, the Dell MD1000 is built to accommodate growing storage needs while ensuring reliability, performance, and ease of use. With its modular design, support for various drive types, robust RAID capabilities, versatile connectivity options, and efficient power management, it represents an excellent choice for businesses looking to enhance their data storage infrastructure.
