Safety and environmental notices xxv

Acclimation

Server and storage equipment (racks and frames) must be gradually acclimated to the surrounding environment to prevent condensation.

When server and storage equipment (racks and frames) is shipped in a climate where the outside temperature is below the dew point of the destination (indoor location), there’s a possibility that water condensation can form on the cooler inside and outside surfaces of the equipment when the equipment is brought indoors.

Sufficient time must be allowed for the shipped equipment to gradually reach thermal equilibrium with the indoor environment before you remove the shipping bag and energize the equipment. Follow these guidelines to properly acclimate your equipment:

•Leave the system in the shipping bag. If the installation or staging environment allows it, leave the product in the full package to minimize condensation on or within the equipment.

•Allow the packaged product to acclimate for 24 hours.1 if there are visible signs of condensation (either external or internal to the product) after 24 hours, acclimate the system without the shipping bag for an extra 12 - 24 hours or until no visible condensation remains.

•Acclimate the product away from perforated tiles or other direct sources of forced air convection to minimize excessive condensation on or within the equipment.

1 Unless otherwise stated by product-specific installation instructions.

Note: Condensation is a normal occurrence, especially when you ship equipment in cold-weather climates. All Dell products are tested and verified to withstand condensation that is produced under these circumstances. When sufficient time is provided to allow the hardware to gradually acclimate to the indoor environment, there should be no issues with long-term reliability of the product.

•An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock. (R001 part 1 of 2)

Caution

•Do not install a unit in a rack where the internal rack ambient temperatures might exceed the manufacturer's recommended ambient temperature for all your rack-mounted devices.

•Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not blocked or reduced on any side, front, or back of a unit that is used for air flow through the unit.

•Consideration must be given to the connection of the equipment to the supply circuit so that overloading of the circuits does not compromise the supply wiring or overcurrent protection. To provide the correct power connection to a rack, refer to the rating labels on the equipment in the rack to determine the total power requirement of the supply circuit.

•(For sliding drawers) Do not pull out or install any drawer or feature if the rack stabilizer brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time.

Safety and environmental notices xxvii

•(For fixed drawers) This drawer is a fixed drawer and must not be moved for servicing unless specified by the manufacturer. Attempting to move the drawer partially or out of the rack might cause the rack to become unstable or cause the drawer to fall out of the rack. (R001 part 2 of 2)

Caution

Removing components from the upper positions in the rack cabinet improves rack stability during relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a room or building:

•Reduce the weight of the rack cabinet by removing equipment, starting at the top of the rack cabinet. When possible, restore the rack cabinet to the configuration of the rack cabinet as you received it. If this configuration is not known, you must do the following:

–Remove all devices in the 32U position (compliance ID RACK-001) or 22U (compliance ID RR001) and above.

–Ensure that the heaviest devices are installed in the bottom of the rack cabinet.

–Ensure that there are little-to-no empty U-levels between devices installed in the rack-cabinet below the 32U (compliance ID RACK-001) or 22U (compliance ID RR001) level, unless the received configuration specifically allowed it.

•If the rack cabinet you are relocating is part of a suite of rack cabinets, detach the rack cabinet from the suite.

•If the rack cabinet you are relocating was supplied with removable outriggers, they must be reinstalled before the cabinet is relocated.

•Inspect the route that you plan to take to eliminate potential hazards.

•Verify that the route that you choose can support the weight of the loaded rack cabinet. Refer to the documentation that comes with your rack cabinet for the weight of a loaded rack cabinet.

•Verify that all door openings are at least 760 x 2032 mm (30 x 80 in.).
