Installing Ac Power Supplies - Dell Networking S3048 Guía De Inicio

WARNING: 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) and
covering the second PSU slot opening (PSU2) with a blank plate.
WARNING: ESD damage can occur if components are mishandled.
Always wear an ESD-preventive wrist or heel ground strap when
handling the S3048–ON and its components.
WARNING: To prevent electrical shock, ensure that the S3048–ON is
grounded properly. If you ground your equipment incorrectly,
excessive emissions may result. To ensure that the power cables meet
your local electrical requirements, use a qualified electrician.
NOTE: The Utility panel consists of two slots, PSU1 and PSU2. Insert
PSUs in either slot.

Installing AC Power Supplies

1. Remove the PSU from the electro-static bag.
2. Remove the PSU slot cover from the S3048-ON.
3. Use the grab handle to slide the PSU into the switch PSU slot. The PSU
slot is keyed such that the PSU can only be fully inserted in one
orientation.
