Exceptions to GLM and Fibre Channel Specifications
IBM42M10SNYAA20 and IBM42M10LNYAA10 comply with the Fibre Channel (100-M5-SL-I, 100-M6-SL-I
100-SM-LL-I) and GLM specifications except for the following:
The GLM specification [1] requires that the Fault line be reset by toggling the EWrap signal.
IBM42M10SNYAA20 and IBM42M10LNYAA10 do not operate this way. The Fault line is reset only when
it has been determined that the laser is operating correctly.
The optical receptacles on the end of the IBM42M10LNYAA10 (long wavelength) do not contain the Fibre
Channel specified “single mode keying” features. Either singlemode or multimode Fibre Channel compli-
ant SC duplex connectors can be inserted into the ports of this GLM.
Laser Safety Compliance Requirements
The IBM42M10SNYAA20 and IBM42M10LNYAA10 are designed and certified as Class 1 laser products.
They are to be used only with another IBM-produced IBM42M10SNYAA20, IBM42M10LNYAA10, or a certi-
fied equivalent in a point-to-point configuration. This is a requirement for proper operation of
IBM42M10SNYAA20 and IBM42M10LNYAA10.
If the power supply voltage runs over 6.0 volts this GLM may no longer remain a Class 1 product. The system
using the GLM must provide power supply protection that guarantees no voltage in excess of 6.0 volts under
all fault conditions.
Connection of a GLM to a non-approved optical source, operating the power supply above 6.0 V, or otherwise
operating the GLM in a manner inconsistent with its design and function may result in hazardous radiation
exposure, and may be considered an act of modifying or new manufacturing of a laser product under US reg-
ulations contained in 21 CFR(J) or CENELEC regulations contained in EN 60825.
The person(s) performing such an act is required by law to recertify and reidentify the product in accordance
with the provisions of 21 CFR(J) for distribution within the USA., and in accordance with provisions of CEN-
ELEC EN 60825 (or successive regulations) for distribution within the CENELEC countries or countries using
the IEC 825 standard.
