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.

The following power supply options are available for the S6100–ON:
● AC or DC power supply with integrated fan
● AC or DC power supply with integrated reverse flow fan
Both PSUs are on the right side of the switch. Power supply 1, PSU1, is on the top of the chassis; power supply 2, PSU2, is on
the bottom of the chassis.

The PSUs have an integrated fan, which you cannot replace individually; if the fan integrated in a PSU fails, you must replace
the entire PSU. You can replace the fan trays individually. For fan tray replacement procedures, see Fans.
WARNING:
Prevent exposure and contact with hazardous voltages. Do not attempt to operate this system with
the safety cover removed.
