Safety Notes
Warning:
The primary hazards of exposure to invisible laser radiation from an optical fiber
communications system are:
ï
Damage to the eye by viewing an unterminated optical fiber or fiber optic connector.
ï
Damage to the eye from invisible laser radiation from viewing a cut fiber or a broken fiber.
Never attempt to view optical connectors that may be emitting laser energy and always avoid possible exposure to
invisible optical laser radiation. Using optical fiber scopes or magnifying lenses may increase the possibility for an
eye hazard. It is recommended that you use an optical power meter to determine if there is optical laser radiation
present or use a remote video display inspection tool to inspect connectors.
WARNING
To avoid possible eye injury, use an optical power meter to ensure there is no
optical power in a cable connected to any HPE fabric module. Even if a fabric
module is powered off, passive optics in an HPE fabric may transmit eye-
damaging optical signals from neighboring fabric modules.
i
No user serviceable parts are inside the chassis other than the power supplies and
fan assemblies. Contact HPE for all repairs
.
i
Only qualified personnel should service or replace HPE fabric modules.
~
The HPE fabric module contains multiple separate power sources. Always make
certain that
all
power sources are disconnected before servicing the unit.
Electrostatic Discharge Precautions
Use Electrostatic Discharge (ESD) precautions when handling an HPE fabric module outside a data
center rack. Once the fabric module is installed in a rack, the mounting hardware provides grounding
through the rack.
ESD Guidelines
Observe the following guidelines to avoid electrostatic discharge (ESD) damage when installing or
servicing the HPE fabric module.
•
Minimize handling of assemblies and components.
•
Assemble or remove equipment only in a static-free work area.
•
Use conductive work surfaces (such as an antistatic mat) to dissipate static charge and wear a
conductive wrist strap to dissipate the accumulation of static charge accumulation.
•
Keep replacement parts in their original static-free packaging.
•
Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.
•
Whenever possible, use tools that do not create electrostatic discharge.
