Telecommunication Regulatory Statement; Electronic Emission Notices - IBM 5594-1AX Installation And User Manual

Risks that are posed by the presence of excessive particulate levels or
concentrations of harmful gases include damage that might cause the device to
malfunction or cease functioning altogether. This specification sets forth limits for
particulates and gases that are intended to avoid such damage. The limits must not
be viewed or used as definitive limits, because numerous other factors, such as
temperature or moisture content of the air, can influence the impact of particulates
or environmental corrosives and gaseous contaminant transfer. In the absence of
specific limits that are set forth in this document, you must implement practices
that maintain particulate and gas levels that are consistent with the protection of
human health and safety. If IBM determines that the levels of particulates or gases
in your environment have caused damage to the device, IBM may condition
provision of repair or replacement of devices or parts on implementation of
appropriate remedial measures to mitigate such environmental contamination.
Implementation of such remedial measures is a customer responsibility.

When you attach a monitor to the equipment, you must use the designated
monitor cable and any interference suppression devices that are supplied with the
monitor.
Table 6. Limits for particulates and gases
Contaminant Limits
Particulate
v The room air must be continuously filtered with 40% atmospheric dust
spot efficiency (MERV 9) according to ASHRAE Standard 52.2
v Air that enters a data center must be filtered to 99.97% efficiency or
greater, using high-efficiency particulate air (HEPA) filters that meet
MIL-STD-282.
v The deliquescent relative humidity of the particulate contamination
must be more than 60%
v The room must be free of conductive contamination such as zinc
whiskers.
Gaseous
v Copper: Class G1 as per ANSI/ISA 71.04-1985
v Silver: Corrosion rate of less than 300 Å in 30 days

The deliquescent relative humidity of particulate contamination is the relative
humidity at which the dust absorbs enough water to become wet and promote ionic
conduction.
