Installing the System
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.
This computer can use I/O cards such as PCI adapters, ESCON, FICON, OSA,
InterSystem Coupling-3 (ISC-3), or other I/O features which are fiber optic-based
and utilize lasers or LEDs.
