Dust and Pollution Control

NonStop servers do not have air filters. Any computer equipment can be adversely

affected by dust and microscopic particles in the site environment. Airborne dust can

blanket electronic components on printed circuit boards inhibiting cooling airflow and

causing premature failure from excess heat, humidity, or both. Metallically conductive

particles can short circuit electronic components. Tape drives and some other

mechanical devices can experience failures resulting from airborne abrasive particles.

For recommendations to keep the site as dust and pollution free as possible, consult

with your heating, ventilation, and air conditioning (HVAC) engineer or your HP site

preparation specialist.

Zinc Particulates

Over time, fine whiskers of pure metal can form on electroplated zinc, cadmium, or tin

surfaces such as aged raised flooring panels and supports. If these whiskers are

disturbed, they can break off and become airborne, possibly causing computer failures

or operational interruptions. This metallic particulate contamination is a relatively rare

but possible threat. Kits are available to test for metallic particulate contamination, or

you can request that your site preparation specialist or HVAC engineer test the site for

contamination before installing any electronic equipment.

Receiving and Unpacking Space

Identify areas that are large enough to receive and to unpack the system from its

shipping cartons and pallets. Be sure to allow adequate space to remove the system

equipment from the shipping pallets using supplied ramps. Also be sure adequate

personnel are present to remove each cabinet from its shipping pallet and to safely

move it to the installation site.

Ensure sufficient pathways and clearances for moving the server equipment safely

from the receiving and unpacking areas to the installation site. Verify that door and

hallway width and height as well as floor and elevator loading will accommodate not

only the server equipment but also all required personnel and lifting or moving devices.

If necessary, enlarge or remove any obstructing doorway or wall.

All modular cabinets have small castors to facilitate moving them on hard flooring from

the unpacking area to the site. Because of these small castors, rolling modular

cabinets along carpeted pathways might be difficult. If necessary, plan for a temporary

hard floor covering in affected pathways for easier movement of the equipment.

WARNING. A fully populated cabinets is unstable when moving down the unloading ramp from

its shipping pallet. Arrange for enough personnel to stabilize each cabinet during removal from

the pallet and to prevent the cabinet from falling. A falling cabinet can cause serious or fatal

personal injury.
