Power Supplies

The Z9100–ON ships with two AC or DC power supplies.
The Z9100–ON supports AC or DC power supplies with two air-flow directions (from the I/O to the PSU
and from the PSU to the I/O). Two PSUs are required for full redundancy, but the system can operate with
a single PSU.
The PSUs are 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 Z9100-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: If you use a single PSU, install a blank plate in the other PSU slot. Dell Networking
recommends using power supply 2 (PSU2) as the blank plate slot. Use a #1 Philips screw driver to
install the blank plate.
NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist
or heel ground strap when handling the Z9100–ON and its components.
