| DANGER
| To prevent a possible shock during an electrical storm, do not
| connect or disconnect cables or station protectors for
| communications lines, display stations, printers, or telephones.
| DANGER
| To prevent a possible shock from touching two surfaces with different
| electrical grounds, use one hand, when possible, to connect or
| disconnect signal cables.
| The following CAUTION notices appear in this installation manual:
| CAUTION:
| The coupling facility, ESCON

, FICON

, and OSA channel laser ports are
| designed and certified for use only with optical fiber and connectors having
| characteristics specified by IBM. The use of any other connectors or fiber
| may result in emission of laser power levels capable of producing injury to
| the eye if directly viewed. Use of non-specified connectors or fiber could
| violate the class 1 certification.
| CAUTION:
| All IBM laser modules are designed so that there is never any human access
| to laser radiation above a class 1 level during normal operation, user
| maintenance, or prescribed service conditions. Data processing
| environments can contain equipment transmitting on system links with laser
| modules that operate at greater than class 1 power levels. For this reason,
| never look into the end of an optical fiber cable or open receptable. Only
| trained service personnel should perform the inspection or repair of optical
| fiber cable assemblies and receptacles.
| CAUTION:
| The doors and covers to the product are to be closed at all times except for
| service by trained service personnel. All covers must be replaced and doors
| locked at the conclusion of the service operation.
| CAUTION:
| Ensure the customer has turned off building power circuit breakers BEFORE
| you connect the frame power cord(s) to the building power.
