Important Points To Remember - Dell Networking S3048 Guía De Inicio

NOTE: Coat the one-hole lug with an anti-oxidant compound prior to
crimping. Bring any unplated mating surfaces to a shiny finish, and coat
with an anti-oxidant prior to mating. Plated mating surfaces must be
clean and free from contamination.
1. Cut the ground cable to the desired length. The cable length must
facilitate the proper operation of fault interrupt circuits. Dell Networking
recommends using the shortest cable route allowable.
2. Attach the one-hole lug to the chassis using an M4x0.7 screw with a
captive internal tooth lock washer, as shown. Torque the screw to 20 in-
lbs.

Important Points to Remember

The S3048–ON is designed to support two hot-swappable power supplies
with integrated fans that provide cooling for the chassis.
• The S3048–ON ships with one power supply. Dell recommends
purchasing a second power supply.
• The PSU slides into the slot smoothly. Do not force the PSU into a slot as
this action may damage the PSU or the S3048-ON chassis.
• The S3048–ON supports AC power supplies with two air-flow directions
(I/O to Utility and Utility to I/O). The S3048–ON does not support mixing
PSU types. The fan airflow direction for the PSUs must be the same.
CAUTION: DO NOT mix airflow directions. Both power supplies must
use the same airflow direction (I/O to Utility or Utility to I/O).
