NEBS Certification
The IBM 8265 Nways ATM Switch has successfully completed testing and evaluation by Bell
Communications Research, Inc, (Bellcore) and has met all requirements for NEBS certification. The
Bellcore analysis determines a device's environmental compatibility and acceptability for applications in
telco central office environments. The telecommunications industry considers NEBS certification a major
prerequisite for the selection of vendor products to be used in central offices. NEBS certification is also
viewed by procurers of private network equipment as an indicator of a product's industrial strength and
robustness.
Bellcore's NEBS evaluation addresses two key areas of environmental compatibility:
1. Electromagnetic compatibility criteria in the areas of:
electrostatic discharge
electromagnetic interference
lightning and AC power faults
electrical safety, bonding, and grounding.
2. Physical compatibility criteria in the areas of:
thermal and fire resistance
earthquake and office vibration
transportation and handling
acoustic noise.
Criteria are defined at three levels: desirable features and functions, conditional requirements, and
mandatory requirements being the most stringent. The 8265 has satisfied the highest level of criteria for all
attempted tests. These tests represent the exhaustive list of NEBS tests for level 3 certification with the
exception of "airborne contaminants". IBM will consider attempting the airborne contaminants test in the
future if required for specific application.
NEBS certification now gives both telco and private network customers the assurance that the 8265 can
meet the requirements of the most demanding segment of networking industry.
In addition to the 8265 chassis itself, the following components have, at the time of publication, received
NEBS certification:
CPSW2 module (Feature Code 6502)
Controller module (Feature Code 8000)
415 W AC power supply (Feature Code 8027)
295 W DC power supply (Feature Code 8028)
WAN 2.5 module (Feature Code 6561)
MSS Server 2.5 module (Feature Code 5401)
155 Mbps multimode fiber daughter card (Feature Code 6580)
155 Mbps singlemode fiber daughter card (Feature Code 6581)
E1/T1/J1 daughter card (Feature Code 6570)
E1/T1/J1 IMA daughter cards (Feature Codes 6670 and 6671)
DS3 daughter card (Feature Code 8502)
