Installing A Fan Module - Dell PowerSwitch S5000 Guía De Introducción

at 26°C ambient temperature. This feature results in lower noise and higher
average fan life. The switch increases the fan speed to maximum if the facility air
condition fails or if a fan fails.
• The fan speed increases and decreases automatically based on the internal
temperature. The switch never intentionally turns off the fans.
• For proper ventilation, position the S5000 in an equipment rack (or cabinet) with a
minimum of 5 inches (12.7 cm) of clearance around the exhaust vents. When you
install two S5000 systems near each other, position the two chassis at least 5
inches (12.7 cm) apart to permit proper airflow. The acceptable ambient
temperature ranges are listed in
• To view the log messages, use the show logging command. For more
information, refer to the System Logs chapters of the
Reference Guide for the S5000 Switch and FTOS Configuration Guide for the
S5000 Switch .
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:
00:00:53: %S5000:3 %CHMGR-2-PSU_TYPE_AIRFLOW_MISMATCH:
Mismatching PSU and FAN airflow detected. Unit 0 shall
get shutdown in next 60 seconds if mismatch not
rectified.
00:00:53: %STKUNIT3-M:CP %CHMGR-1-
PSU_AIRFLOW_COMBO_MISMATCH: Major alarm: Mismatching
PSU and FAN airflow detected in unit 0
The fan modules are field replaceable. Module slot 1 is on the left side of the chassis;
module slot 2 is on the right side of the chassis.
