Power supplies
The S6100–ON supports AC or DC power supplies with two air-ow directions, normal and reverse. Normal airow is from the I/O to the
PSU and reverse airow is from the PSU to the I/O.
Two PSUs are required for full redundancy, but the system can operate with a single PSU. To protect against high-voltage shock, install a
power supply blank in all unused power supply slots.
The PSU is eld replaceable. When running with full redundancy—two power supplies installed and running, you can remove and replace
one PSU without disrupting trac.
CAUTION: To prevent electrical shock, ensure that the S6100-ON is grounded properly. If you do not ground your equipment
correctly, excessive emissions may result. Use a qualied electrician to ensure that the power cables meet your local electrical
requirements.
NOTE: Connect the power supply to the appropriate branch circuit protection as dened by your local electrical codes. Verify
that the remote power source complies with the system input power specications.
NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when
handling the S6100–ON and its components.
