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.

3 Attach the other end of the ground cable to a suitable ground point.
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).
