NOTE:

If a PSU fails, you must completely replace it. There are no field serviceable components in the PSU.

1. Disconnect the power cable from the PSU.

2. Use the grab handle to slide the PSU out of the switch PSU slot.

3. Use the grab handle on the replacement PSU to slide it into the switch PSU slot.

4. Attach the power cord to the replacement PSU.

Important Points to Remember for Installing a Fan

Module

•

The Utility panel consists of four slots numbered from 0 to 3. Insert the fan modules in slots 1 and 2.

•

If a fan module fails, the system continues to operate without a significant degradation in cooling capacity for a six-hour duration.

•

The cooling system is designed such that, during normal operation, the fans typically run at somewhere between 50 and 75 percent of

their maximum speed 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 Dell

Networking OS Command Line Reference Guide for the S5000 Switch and Dell Networking OS 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.

1. Take the fan module out of the shipping box.

2. Use the grab handle to slide the fan module into the switch fan slot, as shown below.
