NOTE:

Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear an ESD-preventive

wrist or heel ground strap when handling the S5000 and its components.

CAUTION:

DO NOT mix airflow directions. The airflow directions are color coded. A red label indicates that hot air is

expelled from the PSU and a blue label indicates that hot air is expelled from the I/O. Both fans must use the same

airflow direction (I/O to Utility or Utility to I/O). The power supplies and fans must have the same color strap. If you

mismatch the airflows, the following error message appears and the system shuts down:

00:02:19: %S5000:0 %CHMGR-2-PSU_TYPE_AIRFLOW_MISMATCH: Mismatching PSU airflow detected.

Unit 0 shall get shutdown in next 60 seconds if mismatch not rectified. 00:02:19:

%STKUNIT0-M:CP %CHMGR-1-PSU_AIRFLOW_COMBO_MISMATCH: Major alarm: Mismatching PSU airflow

detected in unit 0

Assembling and Connecting the Safety Ground

Wire for DC Power Supply

NOTE:

For equipment using –(48–60) V DC power supplies, a qualified electrician must perform all connections to DC

power and to safety grounds. Do not attempt connecting to DC power or installing grounds yourself. All electrical wiring

must comply with applicable local or national codes and practices. Damage due to servicing that Dell EMC did not

authorize is not covered by your warranty.

1. Strip the insulation from the end of the green/yellow wire, exposing approximately 4.5 mm (0.175 inch) of copper wire.

2. Using a hand-crimping tool (Tyco Electronics, 58433-3 or equivalent), crimp the ring-tongue terminal (Jeeson Terminals Inc., R5-4SA

or equivalent) to the green/yellow wire (safety ground wire).

3. Connect the safety ground wire to the grounding post on the back of the system using a #6–32 nut equipped with a locking washer.
