Air Filter; Blade Safety Precautions - VBrick 9000 Series Getting Started Manual

Figure 10. Fan Tray Controls and Indicators

Air Filter

The air intake unit at the bottom of the enclosure has a replaceable filter element. Inspect
and replace the filter element every 90 days—more often in challenging environments. For
best results, use replacement filters from VBrick. You need not power off the shelf to replace
the filter element.
To remove/replace the filter element:

1. Loosen the screws on each side and remove the entire unit.
2. Replace the filter with a VBrick-supplied replacement element.

Blade Safety Precautions

Use common sense when installing the blade server. Do not expose the unit to direct
sunlight, high humidity or wet conditions. Do not block the air vents or impede the airflow in
any way. Before you rack mount the blade server, please take a moment to read the following
important safety precautions.
Restricted Location. Because of hazardous energy circuits on the backplane that are
exposed when the fan tray or the blades are removed, this equipment must be installed
in a restricted location with limited access for authorized users who are familiar with
the electrical hazards and required safety precautions. It should not be used in a home,
school, or other area accessible to the public. To be installed only in restricted access
areas (dedicated equipment rooms, equipment closets, or the like) in accordance with
Articles 110-26, 110-27 or the National Electric Code ANSI/NFPA70, or per the
applicable code in the country of installation.
Operating Temperature. If installed in a closed or multi-unit rack, the operating
ambient temperature may be greater than the room ambient. Install the equipment in an
environment compatible with the maximum ambient temperature (Tma) specified by
the manufacturer.
Reduced Air Flow. Do not restrict air flow in any way. Rack mount the equipment so
that the amount of air flow required for safe operation is not compromised.
Mechanical Loading. Avoid uneven mechanical loading. When rack-mounting the
equipment, be sure that the devices are evenly balanced.
Circuit Overloading. Do not overload the supply circuits. Be aware of the effect that
overloading the circuits can have on overcurrent protection and supply wiring. Refer to
the equipment nameplate ratings for details.
Reliable Earthing. The rack-mounted equipment must be reliably earthed. This
particularly applies to power strips and other indirect connections to the branch circuit
