Installing A Fan Tray - Dell Networking S3100 Series Getting Started Manual

WARNING: The PSU side includes two slots, PSU1 and PSU2. Although
the switch can run on one PSU, Dell Networking highly recommends
using two PSUs for full redundancy and additional cooling. To avoid
overheating when the switch is running with only a single PSU, Dell
Networking recommends using PSU1 (on the left when facing the PSU
side) and covering the second PSU slot opening (PSU2) with a blank
plate.
CAUTION: To prevent electrical shock, ensure that the system is
grounded properly. If you do not ground your equipment correctly,
excessive emissions may result. To ensure that the power cables meet
your local electrical requirements, use a qualified electrician.
CAUTION: Remove the power cable from the PSU prior to removing
the PSU itself. Do not connect power prior to inserting the PSU in the
switch.
NOTE: Ensure that the PSU is correctly installed. When you correctly
install the PSU, the power connector is on the right side of the PSU.
NOTE: Dell Networking recommends supplying power from the switch
PSU to the external power source only after the chassis is mounted in a
rack or cabinet.
