Revision A
Safety / Fiber Optic / ESD Precautions
The following precautions must be followed during all phases of equipment installation,
operation, and servicing. Equipment users are responsible for following warnings and
cautions, and for taking other appropriate steps to assure safe equipment operation. Sun
assumes no liability for failure to comply with these requirements.
■ Safety Precautions
To prevent hazardous conditions and personal injury, follow these safety precautions:
Verify Proper Equipment Grounding
Ensure cabinet frames are properly connected to an electrical earth ground. AC power
supplies require a three-conductor power cable. Source power cables must be plugged in-
to approved three-contact electrical outlets. Power cable jacks and mating plugs must
meet electrical code requirements for the intended area of use and also comply with Inter-
national Electrotechnical Commission (IEC) safety standards.
Avoid Electric Shocks
Only qualified personnel may remove equipment covers for servicing. Before starting a
service procedure, remove conductive metal objects from your person including rings,
watches, necklaces, and badge chains. Use a conductive wrist strap and work mat
grounded to a jack or unpainted metal surface on a cabinet frame. Never touch exposed
connector pins or sockets, or leave ‘live’ cable ends exposed.
Use Only Approved Tools and Test Equipment
Use only approved tools and test equipment supplied in the standard CSE tool kit. Always
ground test equipment to a grounding jack on the cabinet frame. Repair or replace any
damaged tools or test equipment prior to use.
Be Aware of Your Operating Environment
Never operate electrical or electronic equipment in the presence of flammable gases or
fumes, as these can create an explosion hazard.
Never Service or Adjust Equipment Alone
Never service or adjustment equipment unless another person capable of rendering first
aid and resuscitation is present.
Do Not Substitute Parts or Modify Equipment
To assure equipment safety features are maintained, and to avoid introducing additional
hazards, never install substitute parts or modify Sun equipment without explicit permission
from Sun technical support personnel. Never remove, cut, or relocate raised-floor tiles
without first receiving customer permission.
Provide Adequate Equipment Clearances
Make sure there is sufficient clearance around equipment to facilitate airflow and heat dis-
sipation, and to maintain ambient system temperatures within recommended operating
ranges. Provide clearances that allow cabinet doors to open at least 90 degrees, and to
be easily removed for servicing equipment or in emergency situations.
