Install Guide

WARNING: 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 airow directions. The airow 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
airow 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 airows, 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
WARNING: For equipment using –(48–60) V DC power supplies, a qualied 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 Networking
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.
