Table of Contents

The S6100–ON supports AC or DC power supplies with two air-flow directions, normal and reverse. Normal airflow is from the I/O to the

PSU and reverse airflow 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 field replaceable. When running with full redundancy—two power supplies installed and running, you can remove and replace

one PSU without disrupting traffic.

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 qualified electrician to ensure that the power cables meet your local electrical

requirements.

NOTE:

Connect the power supply to the appropriate branch circuit protection as defined by your local electrical codes. Verify

that the remote power source complies with the system input power specifications.

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.
