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.
Sufcient 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.

Unless otherwise stated by product-specic installation instructions.
Note: Condensation is a normal occurrence, especially when you ship equipment in cold-weather
climates. All Dell products are tested and veried to withstand condensation that is produced under these
circumstances. When sufcient 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.
Performing the safety inspection procedure
Before you service the unit, complete the following safety inspection procedure.
1. Stop all activities between the host and the library’s tape drives.
2. Turn off the power to the library by pushing in the Power button on the front of the tape library for 4
seconds.
3. Unplug the library’s power cord from the electrical outlet and the library’s power supply unit.
4. Check the library’s power cords for damage, such as a pinched, cut, or frayed cord.
5. If drives are FC/SAS attached, check the tape drive's FC/SAS cable for damage.
6. Check the top and bottom covers of the library for sharp edges, damage, or alterations that expose its
internal parts.
7. Check the top and bottom covers of the library for proper t. They must be in place and secure.
8. Check the product label at the rear of the library to make sure that it matches the voltage at your
outlet.
