Installation and configuration

WARNING: Before completing the following tasks, review the safety instructions that came with the system.

NOTE: The system is intended for restricted access location.

Installation safety precautions

When mounting an enclosure in a rack, you must follow the safety requirements listed here.

• The rack construction must be capable of supporting the total weight of the installed enclosure(s) and the design must incorporate stabilizing features suitable to prevent the rack tipping, or being pushed over during installation or in normal use.

• When loading a rack with enclosures, load the enclosures into the rack from bottom and remove the enclosures from the top.

• To avoid danger of a rack toppling over, do not slide more than one enclosure out of the rack at a time.

• The system must be operated with low pressure rear exhaust installation [back pressure created by rack doors and obstacles not to exceed 5 Pascals (0.5 mm water gauge)].

• The rack design must consider the maximum operating ambient temperature for the unit, which is

35°C.

• The rack must have a safe electrical distribution system. It must provide over-current protection for the unit and must not be overloaded by the total number of units installed in the rack. When resolving these issues, consider the electrical power consumption rating displayed on the name plate.

• The electrical distribution system must provide a reliable ground for each unit in the rack.

NOTE:

Heavy weight warning.

A fully configured MD1280 enclosure weighs up to 103.7 kg (287.5 lbs). An unpopulated enclosure weighs 64 kg (141 lb). Use appropriate lifting methods.

High temperature warning.

The operating temperature inside the enclosure can reach up to 60° C (140 °F). Be careful when opening drive drawers and removing carriers.

Electrical disconnection warning.

Indicates that all electrical supply connections to the enclosure should be disconnected before proceeding.

Unpacking the system

NOTE: Unpacking, installing, and deploying your Dell Storage must be carried out only by a certified service technician.

Before you begin, make sure the site where you intend to set up and use the Dell Storage has the following:

• 208 V power from an independent source or a rack power distribution unit with a UPS (110 V power will not work.).

• A 5U space in the lower 20U of the rack. If planning to install above the 20U mark, a customerprovided mechanical lift must be made available.

Installation overview

The installation process includes the following general tasks.

CAUTION: If installed in a closed-or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer. For more information, see the Technical Specifications section in this document.

1.

Assemble the rails following the safety instructions and the rack installation instructions provided with your system.

2. Unpack the enclosure.

WARNING: Two people using lift straps are required to avoid injury.

3. Install the enclosures into the rack.

• Always load the rack from the bottom for weight stability.

• If you have fewer than the maximum number of enclosures, you can allow room for expansion.

WARNING: If installing above the lower 20U of a rack, a customer-provided mechanical lift must be used to avoid injury.

4. Insert each disk drive in carrier (DDIC) into the enclosure one at a time.

• Protect the hard drive from static discharge.

• Handle DDICs by the edges of the frame.

CAUTION: If the enclosure system operates for too long (depending on altitude) with drive drawers open, the enclosure can overheat, causing power failure and data loss. Such use may invalidate the warranty.

5. Close the drive drawers after adding all DDICs.

Drawer release (2) — One on each side of drawer. Releases the open-drawer locks. a.

Pull and hold both drive drawers releases, and then slightly push the drawers inside.

b.

Release and push the drive drawers in until it clicks into place.

WARNING: After releasing the open-drawer locks, move hands away from the slides before pushing the drawer in to avoid injury.

Connecting the power cables

Figure 2. Connecting the power cables

Ensure that the power switch is OFF before connecting the power cables.

CAUTION: Be careful when closing the rear rack door to ensure that power cords have adequate space as some racks might not be sufficiently deep.

Securing the power cables

Figure 3. Securing the power cables

1.

Secure the power cables firmly to the bracket using the clip provided.

2. Plug the other end of the power cables into a grounded electrical outlet or a separate power source such as an uninterrupted power supply (UPS) or a power distribution unit (PDU).
